McKesson Probes Data Theft After ShinyHunters Claims Access to Patient Records




McKesson Corporation is investigating a cybersecurity incident involving unauthorized access to third-party applications and data exfiltration, while the ShinyHunters extortion group claims it stole approximately 284 million patient-related records from the healthcare and pharmaceutical distribution company.

McKesson said it discovered the incident on August 25 and immediately activated its incident-response procedures. The company has brought in external cybersecurity specialists to assist with the investigation, which it said remains in its early stages.

In a filing with the U.S. Securities and Exchange Commission, McKesson said it has not determined that the incident is material or that it has had, or is reasonably likely to have, a material impact on its financial condition or operations.

The company confirmed in a separate customer notice that the incident involved unauthorized access to third-party applications and the exfiltration of data. McKesson has not identified the affected applications, disclosed how the attackers obtained access, or confirmed what information was taken.

Customers could also experience intermittent service degradation believed to be related to the incident. McKesson said it was not proactively disconnecting systems within its environment.


ShinyHunters claims employee accounts were compromised

ShinyHunters claims it obtained initial access through voice-phishing, or vishing, attacks targeting multiple McKesson employees.

According to the group, the attacks resulted in the compromise of several employee Okta single sign-on accounts. Those accounts were allegedly used to access McKesson's Salesforce and Snowflake environments.

The group claims it obtained extensive access to Salesforce, including support cases, and extracted a larger volume of patient-related information from Snowflake.

ShinyHunters alleges that approximately 1 TB of data was removed over four days, from August 21 through August 25.

The group has claimed that the Snowflake data contained roughly 284 million patient-related records. However, it later clarified that this figure represents individual database records or lines, rather than 284 million unique patients.

ShinyHunters also said it has not completed its analysis of the stolen material and therefore cannot determine how many individuals are represented in the dataset.

The alleged information includes names, addresses, dates of birth, Social Security numbers, patient IDs, phone numbers, email addresses, Medicaid numbers and medical record numbers. The group also claims the data contains medication and allergy information, illnesses, disabilities, appointments, physician details, prescriptions and medication shipments.

Other allegedly stolen material includes information relating to deceased and terminally ill patients, invoices, employee data, Salesforce records, internal communications, and information about healthcare providers and clinics using McKesson's services.

McKesson has not confirmed any of these specific data categories, and the claims about the stolen information have not been independently verified.


McKesson domain follows ShinyHunters pattern

The alleged campaign also involved the "mckesson[.]claims" domain.

The domain follows a pattern previously associated with ShinyHunters activity. ReliaQuest has documented campaigns in which domains using a targeted company's name or abbreviation alongside the ".claims" top-level domain were used to impersonate help-desk or IT personnel.

The technique is particularly relevant to the alleged McKesson attack because social engineering is increasingly being used to obtain legitimate employee credentials rather than deploying malware directly against an organization's infrastructure.

ReliaQuest recently documented an attempted attack against its own employees in which an attacker used a lookalike domain, impersonated a security employee and attempted to persuade staff to authenticate through a fraudulent SSO page. Additional security controls prevented the attacker from reaching business applications or customer information.

Health-ISAC has also warned healthcare organizations about an increase in ShinyHunters activity involving social engineering, identity compromise and subsequent access to cloud and SaaS platforms.

Its analysis describes an attack chain in which threat actors use vishing or help-desk manipulation to compromise identity-provider accounts before moving into connected services. Such access can allow attackers to retrieve large volumes of information through legitimate cloud applications.

Research from the Retail & Hospitality ISAC has further linked ShinyHunters to the abuse of OAuth relationships and SaaS applications. By operating through legitimate identities or application permissions, attackers can make unauthorized activity more difficult to distinguish from ordinary cloud usage.

The alleged McKesson intrusion has not been independently confirmed to have followed this entire sequence, but the claimed compromise of employee SSO accounts followed by access to Salesforce and Snowflake is consistent with the identity-focused tactics researchers have been tracking.


$55 million ransom demand claimed

ShinyHunters claims it contacted McKesson after completing the alleged data theft on August 25 and demanded $55,236,150 in ransom, giving the company 72 hours to respond.

The group claims McKesson did not negotiate over the demand.

McKesson has not publicly confirmed the ransom demand or its alleged communications with the extortion group.

The incident comes as ShinyHunters-linked attacks continue to target healthcare and health-technology organizations. Recent organizations reportedly targeted by the group include Medtronic, DentaQuest, iRhythm, One Medical and AdaptHealth.

For McKesson, the immediate question remains the actual scope of the incident. The company has confirmed unauthorized access to third-party applications and data exfiltration, but has not established which systems were affected, what information was taken or how many individuals may ultimately be impacted.

Until McKesson completes its investigation, the 284 million-record figure and the specific claims surrounding the alleged Snowflake and Salesforce compromise remain unverified.

Social Engineering Attack
Credential Phishing Cybersecurity Data Breach Data Exposure RingCentral Data Breach ShinyHunters Social Engineering Attack

RingCentral Breach Exposes Personal Data of 1.6 Million Accounts


 

An attack on RingCentral, which was targeted at social engineering, has led to a data breach that could have exposed personal information of around 1.6 million individuals. In July, RingCentral detected the unauthorized activity during a campaign. The company said it immediately responded to the incident and launched an investigation with the assistance of an external forensic firm in order to contain the unauthorized activity. 

In light of the remediation measures implemented, RingCentral has not detected any further unauthorized activity. In addition, RingCentral clarified that only a limited number of its customers were affected by the incident and that those who were potentially affected were contacted directly. Furthermore, the company clarified that its services remain operational, and that its core platform was unharmed. 

Despite the lack of identification of the threat actor by the company, the ShinyHunters extortion group reportedly listed RingCentral on its Tor-based leak site in late July. As a result of the group's claim that they obtained over 623GB of data, there is further concern about the size of the attack. After investigating the leaked data, Have I Been Pwned confirmed that the dataset contains information associated with approximately 1.6 million accounts, including names, email addresses, telephone numbers, and physical addresses. 

The disclosure supports ShinyHunters' claims, even though RingCentral has not publicly attributed the incident to the group or provided details concerning how the attackers gained access to their system. A broader pattern of data theft attacks has been claimed by ShinyHunters against customers of major cloud and SaaS providers, including Salesforce and Snowflake, as well as the incident described above. This group has targeted third-party platforms and integrations increasingly, using stolen corporate data to extort companies. 

A recent lawsuit against Oracle PeopleSoft underscores the extent and persistence of the data theft operations of the organization. It has been possible for independent researchers to assess the scope of the exposure after publishing the 280GB archive. Has I Been Pwned reported approximately 1.6 million unique email addresses in the leaked data, along with names, telephone numbers, and physical addresses. 

A RingCentral representative has not independently verified the attacker's claims or disclosed the number of people affected. The incident also illustrates the effectiveness of voice-based social engineering, a strategy increasingly associated with ShinyHunters. Threat actors conduct these attacks by impersonating IT personnel and leading employees to a convincing login page with the intent of capturing passwords and authentication codes. It is possible that conventional one-time-password MFA will not be sufficient to prevent account compromise due to the attack's reliance on manipulating the employee rather than breaking the underlying security technology. 

As a result, security experts are increasingly recommending phishing-resistant methods, such as FIDO2 passkeys. These passkeys bind authentication to a legitimate website, preventing credentials from being regenerated through a fraudulent website. 

The details of the authentication method used by the compromised account have not been disclosed, nor have any controls been implemented to prevent phishing attacks. It is imperative to note that exposing names, phone numbers and physical addresses poses a risk beyond the initial compromise. These disclosures can provide attackers with sufficient context to carry out further impersonations and phishing attempts in a convincing manner. 

ShinyHunters has continued to focus on data theft and extortion rather than traditional ransomware, as demonstrated by the RingCentral incident, which illustrates how a single successful social engineering attack can lead to a much larger privacy and security issue as it progresses. 

The RingCentral incident has raised several questions, primarily regarding the extent of the exposure and the means by which the accounts were compromised. Have I Been Pwned has identified approximately 1.6 million email addresses in the leaked dataset, whereas RingCentral has described the customer base as limited. 

To determine the full impact of this incident, it is critical to reconcile those figures, along with more information about the compromised accounts, in order to determine the full extent. In organizations using RingCentral or similar cloud communication platforms, it is critical to establish strong defenses against social engineering at the earliest opportunity. During security awareness training, attention should be paid to suspicious calls, credential-harvesting websites, and requests for authentication codes. 

Organizations handling sensitive or regulated information should assess notification and compliance requirements for phishing attacks, multiple factor authentication, credential resets for potentially compromised accounts, and monitoring for follow-up phishing attacks and business email compromises. A wider question is raised by the incident about security at the intersection of technology and individuals. 

Even organizations with well-established security controls can be exposed if an attacker convinces an employee to bypass these controls. The breach thus serves as a reminder to RingCentral customers that safeguarding communication systems requires not only strong technical controls, but also preparation for social engineering tactics that are becoming increasingly convincing in order to target employees.

ShinyHunters Data Leaks Fuel $2,000 Sextortion Email Scam

 

Cybercriminals are exploiting email addresses exposed in previous ShinyHunters data leaks to conduct a new sextortion campaign demanding $2,000 in Bitcoin. The fraudulent messages falsely claim that ShinyHunters compromised victims’ phones and computers, accessed their cameras and microphones, and recorded them visiting adult websites. However, the campaign appears to involve unrelated scammers who downloaded previously leaked information and are using it to make their threats appear credible. 

The emails reportedly use random sender addresses and names such as “ShinyHunters” or “You’ve Been HACKED.” Their subject line commonly reads “Information about your online security.” In the messages, attackers mention companies whose databases were previously exposed, including Amtrak, Hallmark, Substack, Betterment, CarGurus, ADT, Panera Bread, and McGraw Hill. By identifying a company connected to the recipient’s email address, scammers attempt to create the impression that they specifically targeted the victim. 

The scam messages claim that attackers installed malware capable of accessing a victim’s microphone, camera, keyboard, photographs, browsing history, conversations, and contact list. They then threaten to send allegedly recorded intimate videos to the recipient’s family, friends, colleagues, and business contacts unless payment is made within 48 hours. The emails also instruct recipients not to contact law enforcement, reply, or reset their devices, claiming that stolen data is stored on remote servers. These warnings are intimidation tactics rather than evidence of a genuine device compromise. 

According to the report, the campaign may have begun in April, with victims and organizations sharing similar warnings online. Betterment acknowledged that some customers received threatening emails and described them as a common extortion scam. The company emphasized that knowing someone’s email address does not give criminals the ability to install malware or access that person’s device. It advised recipients not to reply, pay, click links, or open attachments, while asking anyone who interacted with the message to contact its fraud team. 

People receiving these emails should remain calm and avoid paying the Bitcoin demand, because payment does not guarantee that scammers will stop contacting them. Recipients should preserve the message as evidence, report it to their email provider and relevant cybercrime authorities, then delete it after checking for suspicious account activity. They should also use unique passwords, enable multifactor authentication, update devices, and monitor accounts associated with the exposed email address. The campaign demonstrates how data stolen in one breach can later be reused by unrelated criminals to support convincing but false threats.

Third-Party Breach
cybersecurity news Data Breach Ernst & Young ShinyHunters Supply Chain Attack Tax Data Exposure Third-Party Breach

ShinyHunters Claims Responsibility for EY Data Breach as Investigation Continues


 

The cyberattack involving Ernst & Young (EY) has entered a new phase after the ShinyHunters extortion group claimed responsibility for the intrusion, alleging that it stole data from the third-party support ticket platform used by the global professional services firm. While EY has acknowledged the underlying breach, the company has not confirmed the group's claims, and no leaked data has been independently verified at the time of writing.

The development comes weeks after EY disclosed that an unauthorized party had accessed a third-party support ticket platform used by its IT teams between March 28 and April 12, 2026, potentially exposing documents associated with client tax preparation. The firm had previously informed affected customers that files stored within the support environment could contain personal and financial information submitted through IT support requests, along with documents related to tax services.

According to breach notifications filed with several U.S. state regulators, the exposed records may include sensitive information such as client names, addresses, Social Security numbers, financial account details, payment card information, and other tax-related records. However, EY has not disclosed how many individuals were affected, whether customers outside the United States were impacted, or the identity of the third-party support platform involved in the incident.

The latest development centers on ShinyHunters' public assertion that it carried out the attack and obtained data from the compromised environment. The group has reportedly threatened to publish the allegedly stolen information if its demands are not met. Despite these claims, EY has neither attributed the incident to ShinyHunters nor confirmed that the attackers possess company or client data. Security researchers also note that threat actors have, on occasion, exaggerated or misrepresented claims to increase pressure on victims, making independent verification essential before drawing conclusions.

EY has stated that it immediately activated its incident response procedures after detecting suspicious activity and engaged an independent cybersecurity firm to assist with forensic analysis and remediation. The company says it has contained the unauthorized access, secured the affected environment, and notified relevant federal law enforcement authorities. It also maintains that its investigation has found no evidence that the compromised information has been misused or that individual clients were specifically targeted.

As part of its response, EY continues to provide eligible affected customers with 24 months of complimentary Experian identity restoration, identity monitoring, and credit monitoring services, with enrollment available through October 31, 2026.

Although the breach itself has already been disclosed, the emergence of an alleged threat actor highlights how cyber incidents often evolve long after the initial discovery. Public claims made by ransomware or extortion groups can influence regulatory scrutiny, customer communication, and incident response strategies, even before their assertions are independently verified.

The incident also reinforces the importance of third-party risk management. Organizations that rely on external platforms to process or store sensitive customer information should continuously assess vendor security controls, restrict unnecessary access to confidential data, and maintain comprehensive monitoring and incident response capabilities to reduce the impact of supply chain compromises.

Abbott Cyber Incident Abbott Laboratories Cancer Diagnostics Security Cyber Attacks Data Breach Healthcare cybersecurity LabCentral Breach Microsoft Entra ShinyHunters

Abbott Investigates Two Cyber Incidents Following Extortion Claims


 

Two separate cybersecurity incidents are being investigated by Abbott Laboratories after threat actors reportedly gained access to the company's systems and accessed sensitive information. While one incident has been linked to the ShinyHunters extortion group, the other involves claims of unauthorized access to Abbott's LabCentral customer portal. The company said both incidents are being investigated, and operations have not been disrupted. 

Both incidents have not adversely affected Abbott's business operations, manufacturing, laboratory services, product availability, or customer support. According to the company, the unauthorized access was restricted to systems that operate independently of Abbott's core infrastructure within its Cancer Diagnostics business, with no impact reported across other business units or sites due to the unauthorized access discovered. 

Several legacy Exact Sciences systems were discovered to have been accessed unauthorizedly by Abbott's Cancer Diagnostics business. As a consequence of the ShinyHunters extortion group listing the company on its data leak site, Abbott confirmed the breach, and threatened to publish allegedly stolen information if negotiations were not held. Exact Sciences is part of Abbott's Cancer Diagnostics division, which the company acquired earlier this year for $21 billion. 

Aside from Abbott's core systems, Exact Sciences' legacy infrastructure operates separately, which limits the scope of the incident. According to Abbott, the incident is isolated to the Cancer Diagnostics division and has not affected manufacturing, laboratory operations, product availability, patient services, or any other Abbott business systems.

A notification was sent to law enforcement, the company activated its incident response procedures, and external cybersecurity experts were engaged. In addition, Abbott stated that the incident will not negatively affect its financial performance. In response to the incident, Abbott has not provided information regarding the type of information that was accessed, noting that its investigation is ongoing. 

The company claims to have gained initial access to a Microsoft Entra single sign-on (SSO) account by launching a voice phishing (vishing) attack targeting Abbott employees in mid-June. A number of enterprise platforms, including Microsoft Entra, ServiceNow, SharePoint, Databricks, and Coupa, were accessed by the group, which alleges that internal documents, contracts, customer information, and millions of medical records containing personally identifiable information (PII) have been exfiltrated. 

These claims have not been independently verified, however. Separately, a threat actor claiming the name ShadowByt3$ has been associated with the breach of Abbott's Core Laboratory Diagnostics business by exploiting compromised customer credentials by accessing the LabCentral customer portal hosted by a third party. It has been claimed that the attacker has obtained technical documentation, manufacturing certificates, regulatory files, and other product-related information. 

LabCentral was investigated by Abbott, but the attacker's claims were disputed, as the portal only contains publicly available technical reference materials such as operating manuals, troubleshooting guides, and product specifications. The company indicated that confidential business information and sensitive customer information are not included in the environment. 

In the LabCentral portal, Abbott explained that it is hosted by a third party provider and serves as a repository of publicly available technical reference documents, including operating instructions, troubleshooting guides, and product specifications. In accordance with the company, sensitive customer information or proprietary business data is not known to have been compromised as a result of the reported incident. 

There has been a growing trend of cyberattacks targeting healthcare and medical technology over the past few years. In recent months, a number of companies, including Clover Health, Stryker, Medtronic, Novo Nordisk, and West Pharmaceutical Services, have reported cybersecurity incidents, illustrating the increasing risks associated with handling patient and healthcare-sensitive data. Several cyber-incidents have occurred in the medical technology sector in recent months, causing significant damage to the industry. 

A number of companies, including Stryker, Medtronic, Intuitive Surgical, iRhythm, and AdaptHealth, have reported cybersecurity incidents as well, underscoring the growing threat landscape for healthcare and medtech organizations. As of yet, neither ShinyHunters nor ShadowByt3$ has disclosed the data that they claim to have stolen. In addition to engaging external cybersecurity experts and notifying law enforcement, Abbott has also continued to investigate the possibility of access to any potentially sensitive information.

In addition, Abbott stated that it does not anticipate either incident to negatively impact its business or financial results. Abbott's ongoing investigations highlight the increasing cybersecurity challenges in the healthcare and medical technologies industries. 

However, despite the company's assurances that operations remain unaffected and that no sensitive customer information has been exposed, the incidents demonstrate how important it is to take quick action, to use robust security measures, and to continuously monitor against cyber threats as they evolve.

Zero-Day Exploit
Council of Europe CVE-2026-35273 Cyber Extortion Data Breach Data Leak Employee Data Exposure Identity Theft Oracle PeopleSoft Vulnerability ShinyHunters Zero-Day Exploit

Council of Europe Data Breach Exposes Records of 10000 Employees After ShinyHunters Leak


 

Council of Europe is investigating a major data breach following the public release of approximately 297 GB of sensitive employee data by cybercriminal group ShinyHunters following the expiration of a ransom deadline. 

An archive has been leaked that contains information regarding more than 10,000 current and former employees, contractors, and job applicants dating from 15 years ago. As one of Europe's leading human rights organizations since 1949, the Council of Europe has been an official observer at the United Nations since 1949. It represents 46 member states and is a central force in promoting democracy, human rights, and the rule of law throughout Europe. 

Since the information it holds is sensitive, the breach of confidentiality is particularly significant. As reported by ShinyHunters, more than 429,000 files, including personnel data, were obtained from multiple Council departments, including human resources and administrative units. This was one of the largest breaches of personal data involving an intergovernmental organization in Europe. 

Information available indicates that payroll records, bank account information, medical information, tax information, social security information, salary histories, personnel files, and thousands of CVs were exposed. Due to the large size of the dataset, identity theft, financial fraud, and highly targeted phishing are significantly more likely to occur. It has been reported that the breach is related to CVE-2026-35273, a critical 9.8-severity zero-day vulnerability affecting Oracle PeopleSoft's Environment Management Hub (PSEMHUB). 

According to security researchers, the vulnerability allowed attackers to execute arbitrary code remotely without authentication. According to Google's Mandiant team, more than 100 organizations had actively exploited the vulnerability prior to Oracle's release of security guidance. Using the zero-day vulnerability in combination with older vulnerabilities, ShinyHunters obtained persistent access, migrated laterally through compromised environments, and exfiltrated data while posing as legitimate users. 

The exploit was conducted between May 27 and June 9, before mitigations were available. ShinyHunters has also altered its extortion strategy significantly following the Council of Europe declining to meet the ransom demand. In response to the Council's refusal to pay the ransom, ShinyHunters announced it would permanently distribute stolen datasets through multiple mirror sites and torrent networks, thereby reducing the likelihood of future takedown efforts.

In addition, the incident adds to the growing number of campaigns involving ShinyHunterS Researchers have recently linked the group to attacks targeting multiple organizations, while Google's threat intelligence team has linked the group's latest activity to widespread exploitation of the Oracle PeopleSoft zero-day vulnerability before mitigations were available. 

According to a brief statement issued by the Council of Europe, the organization was "investigating the matter and assessing the situation." Further comment was not provided. The organization has not yet announced a formal notification process or measures to protect individuals' identities. Zero-day exploitation and data extortion campaigns are becoming increasingly prevalent, with public disclosure increasingly taking precedence over traditional ransomware encryption. 

The threat of persistent leak strategies is increasing, which is why organizations are being urged to strengthen vulnerability management, accelerate patch deployment, and improve incident response to minimize both institutions and individuals' long-term risks.

Cyberattack Data Breach Healthcare cybersecurity Medtronic patient data exposure personal information breach ShinyHunters

Medtronic Alerts Customers After Data Breach Exposes Personal Information

 

Healthcare technology company Medtronic has started informing affected customers about a cybersecurity incident that resulted in unauthorized access to their personal information.

The company had earlier disclosed that its corporate IT infrastructure had been compromised by hackers. The cyber extortion group ShinyHunters later claimed responsibility for the attack, alleging it had obtained around 9 million records containing personally identifiable information (PII) and internal corporate data.

According to the notification shared by the company, “On April 15, 2026, Medtronic became aware of unusual activity on certain corporate IT systems.”

The notice further states, “Medtronic launched an investigation with the assistance of leading third-party cybersecurity experts to determine the impact and scope of the incident.”

Following the investigation, the company concluded that “The investigation determined that from April 13 to April 19, 2026, an unauthorized actor accessed certain Medtronic corporate IT systems.”

The information that may have been exposed includes:

  • Full name

  • Contact information

  • Date of birth

  • Social Security number

  • Health-related information

ShinyHunters is known for publishing stolen information when ransom demands are not met. The group reportedly added Medtronic to its dark web leak site on April 18, claiming it possessed more than 9 million records and warning that the data would be released if a ransom was not paid by April 21.

However, the listing disappeared from the group's portal later that month. In its customer notification, Medtronic clarified that the compromised data has not been made publicly available online.

Medtronic operates in over 150 countries and employs approximately 95,000 people, generating annual revenue of around $33.5 billion.

Despite the breach involving customer information, the company has reassured users that its medical devices continue to operate safely and were not impacted by the cybersecurity incident.

Customers receiving breach notifications are being encouraged to enroll in the company's complimentary 24-month credit monitoring and identity theft protection program to reduce potential risks.

The company has also advised affected individuals to stay alert for suspicious emails, messages, or calls that could exploit the exposed information for phishing, social engineering, or other fraudulent activities. Customers are also encouraged to regularly review their account activity for any signs of unauthorized access.

CVE-2026-35273 Data Breach Nissan data breach Oracle PeopleSoft vulnerability Oracle zero-day ShinyHunters

Nissan Americas Confirms Employee Data Breach After Oracle PeopleSoft Zero-Day Exploited by ShinyHunters

 

iNissan Americas has confirmed a cyberattack that resulted in a data breach affecting current and former employees across the United States, Canada, Mexico, and Brazil. The company said the breach occurred after cybercriminals exploited a critical zero-day flaw in Oracle PeopleSoft software. Security researchers have linked the campaign to the financially motivated hacking group ShinyHunters, also known as UNC6240 or Bling Libra.

The attack leveraged CVE-2026-35273, a critical vulnerability with a CVSS score of 9.8. The flaw exists in the Updates Environment Management (PSEMHUB) component of Oracle PeopleSoft PeopleTools versions 8.61 and 8.62. It allows attackers to move from an unauthenticated Server-Side Request Forgery (SSRF) attack to full Remote Code Execution (RCE) without requiring user interaction or authentication. Because the vulnerability can be exploited over standard HTTP, any exposed and unpatched server is at significant risk.

Oracle released an emergency security update on June 10, 2026, to address the flaw. Two days later, the vulnerability was added to the U.S. Cybersecurity and Infrastructure Security Agency’s (CISA) Known Exploited Vulnerabilities (KEV) catalog after evidence of active exploitation.

According to security researchers at Mandiant and Google’s Threat Intelligence Group (GTIG), the ShinyHunters group began exploiting the vulnerability as early as May 27, 2026—more than two weeks before Oracle publicly disclosed the issue. During that period, attackers reportedly compromised more than 300 Oracle PeopleSoft instances across over 100 organizations using automated attack tools.

Breach notifications submitted to the California Attorney General’s Office revealed that Nissan Americas was among the organizations impacted during the wider campaign. The company's investigation found that the intrusion occurred between May 27 and June 9, 2026.

The compromised information may include employee contact details, banking information, Social Security Numbers (SSN), Social Insurance Numbers (SIN), National Identification Numbers, financial and tax records, as well as dependent and beneficiary information. The incident affects both current and former employees in the U.S., Canada, Mexico, and Brazil.

Following the discovery of the breach, Nissan activated its incident response procedures, brought in external cybersecurity experts, and coordinated with law enforcement agencies. As part of its containment measures, the company limited payroll system access, allowing employees to view pay slips and modify direct deposit details only through corporate network computers or secure VPN connections. Additional identity verification measures have also been introduced for payroll-related requests. Nissan said it is providing complimentary credit monitoring and dark web monitoring services to eligible affected individuals.

Mandiant's investigation found that attackers installed MeshCentral remote management agents on compromised systems while disguising them as legitimate Microsoft Azure services, including meshagent64-azure-ops.exe. Command-and-control communications were routed through wss://azurenetfiles[.]net:443/agent.ashx.

The attackers also carried out post-compromise activities such as reviewing PeopleSoft configurations, moving laterally across networks, and compressing stolen data using zstd before exfiltration. Infected servers were left with a ransom note named README-IF-YOU-SEE-THIS-YOUVE-BEEN-HACKED.TXT.

Cybersecurity firms Rapid7 and Mandiant have urged organizations running Oracle PeopleTools 8.61 or 8.62 to immediately apply Oracle’s security updates. They also recommend disabling or restricting access to the PSEMHUB service, blocking external access to /PSEMHUB/* and /PSIGW/HttpListeningConnector, monitoring outbound SMB traffic for potential NetNTLM hash capture attempts, investigating systems for signs of compromise even after patching, and rotating credentials that may have been exposed.

The incident represents the second major Oracle ERP zero-day vulnerability with a CVSS score of 9.8 to be actively exploited in less than eight months. It follows the exploitation of CVE-2025-61882 in Oracle E-Business Suite by the Cl0p ransomware group in 2025, highlighting the growing focus of organized cybercriminal groups on enterprise resource planning (ERP) platforms.

Third-Party Risk
Cloud Security Data Breach EdTech Cybersecurity FulcrumSec Learning Management System ShinyHunters Student Information System Supply Chain Attack Third-Party Risk

EdTech Software Suppliers Become the New Target for Cyber Attackers


Education is witnessing a notable shift in the cyber threat landscape in which attackers are bypassing individual schools in favor of software providers that support modern digital learning. Education technology (EdTech) vendors have emerged over the last several years as valuable supply chain targets, including learning management systems (LMS), student information platforms, and cloud-based academic services. 


Through a single compromise, threat actors can gain access to thousands or hundreds of educational institutions across a wide range of industries. The recent attacks on the Canvas platform of Instructure, which disrupted online examinations, as well as the large-scale security breach of PowerSchool, which exposed sensitive student data, underscore how cybercriminals are evolving their tactics so that they can maximize operational disruption, data theft, and financial leverage by striking the technology ecosystem instead of the end users. 

With an increased reliance on cloud-native educational infrastructure, financial motivated threat actors have also become increasingly exposed to attacks. Recent activity attributed to groups such as ShinyHunters and FulcrumSec indicates this shift toward more targeted and technically sophisticated attacks against the EdTech sector. 

The ShinyHunters hacking collective has been reported to have compromised learning platforms serving educational institutions around the world, allegedly stealing millions of records containing names, email addresses, physical addresses, and other personally identifiable information (PII) from them. 

Several security assessments have linked these compromises to vulnerabilities such as insufficiently protected API endpoints and exposed cloud databases, vulnerabilities that frequently appear when rapidly expanding EdTech providers prioritize scalability over mature security controls. Data exposed on dark web marketplaces has increased the risks of phishing, credential abuse, identity theft, and follow-on attacks, reinforcing concerns that the adoption of student information systems, learning management systems, and other cloud-based academic platforms outpaces the establishment of robust cybersecurity governance within the education technology supply chain. 

In March of 2026, ShinyHunters allegedly compromised the widely used Infinite Campus Student Information System (SIS) and exfiltrated personally identifiable information from more than 137,000 school staff accounts through a Salesforce-related data theft incident. The campaign has continued to expand in scope throughout 2026.

Considering Infinite Campus' extensive footprint in the U.S. education sector, the breach has broader implications for the organization. Infinite Campus supports approximately 3,200 school districts and manages records for approximately 11 million students from 46 different states. As of June 16, 2026, ShinyHunters also identified Glendale Community College, Moody Bible Institute, Illinois Central College, and Houston City College as its latest victims. 

In contrast to conducting isolated attacks against individual campuses, the increasing victim list illustrates a deliberate strategy to target centralized education platforms that can affect multiple institutions at once rather than focusing on isolated attacks.

There has been a parallel escalation in the ransomware ecosystem where FulcrumSec has claimed responsibility for a large-scale breach involving a Singapore-based international educational network, the Global Schools Foundation. Several critical systems across multiple countries were disrupted as a result of the attack, resulting in a substantial amount of sensitive information being stolen. Students and staff had limited access to essential academic and administrative services as a result of the attack. 

In an unsuccessful ransom negotiation, the group threatened to publish the stolen information. There are 33,088 passport records in the stolen dataset, covering 66 nationalities, 221 million attendance records, 9.4 million internal messages, 143,494 employee salaries, over 616,000 emails attaching medical and identification documents, 112 source code repositories, 168 entries in AWS Secrets Manager, and evidence of a previous ransomware attack dating back to 2022. 

FulcrumSec has previously been connected to cloud-focused intrusions involving platforms hosted on Amazon Web Services, MongoDB, and Google Cloud Platform (GCP), reflecting an attack that extends beyond personal data into operational infrastructure, application code, and cloud secrets. In addition to breaches affecting LexisNexis and Australian fintech company youX, which underscores a consistent focus on cloud-resident data and double extortion activities, these breaches demonstrate an increased focus on cloud-resident data. 

Although large-scale ransomware campaigns continue to make headlines, not every breach in education stems from sophisticated intrusion techniques. By misconfiguring third-party cloud applications, sensitive information may be exposed just as effectively, without the attacker having to overcome security controls in any case. 

One such incident was brought to the attention of the school by parents who discovered that a feature within a third-party absence management platform provided families with the opportunity to view free-text comments submitted by other parents regarding requests for student absences. While the vendor confirmed that the attached attachments were inaccessible, the exposed comment fields may contain sensitive information voluntarily provided by guardians, including medical appointments, illness details, and other private information about students. 

In this instance, it demonstrated how seemingly minor application logic errors can adversely affect data confidentiality when privacy controls are not appropriately implemented. Upon discovery, both the educational institution and its software provider coordinated an incident response. After informing the vendor of the vulnerability, they were able to develop and deploy a software update that remedied the vulnerability prior to ensuring their own environment was updated. 

Besides applying the fix, administrators were required to conduct a comprehensive forensic investigation to determine the duration of the exposure, determine which records were visible, identify users who accessed the vulnerable feature by analyzing system logs, and determine what categories of personal information may have been compromised as a result. 

According to those findings, the incident met the requirements for mandatory regulatory reporting and formal notification was required for affected students, parents, and guardians. At the same time, the institution was required to maintain communication with the families who initially reported the issue while documenting the incident for compliance purposes. 

Due to the vulnerability affecting a shared cloud platform, the vendor was required to notify each school which used the feature, distribute an updated version, and ensure these schools applied the update. This incident illustrates how vulnerabilities within centralized education platforms may rapidly evolve into ecosystem-wide risks. It is equally up to software providers to provide timely patches and transparent communication as it is up to educational institutions to protect student data. 

Together, these incidents demonstrate that effective cybersecurity does not limit to the protection against external attackers in the education sector. The breach response process requires significant operational effort, which involves technical teams, compliance personnel, vendors, and institutional leadership, regardless of whether the root cause is ransomware, cloud misconfigurations, insecure APIs, or human error. Additionally, these incidents illustrate the importance of good vendor governance, secure software development, continuous risk assessments, and an incident response plan that has been extensively tested.

With instructional institutions increasingly relying on cloud-based platforms, organizations that invest in proactive security controls and supplier oversight will be better prepared to minimize operational disruptions, protect sensitive data, and comply with regulatory requirements. 

As schools increasingly rely on interconnected cloud platforms to deliver educational services, the sector has experienced a fundamental shift in its cyber risk profile, making software providers and technology partners just as important as schools themselves to the protection of institutional information. Operational resilience has been demonstrated in recent incidents to depend on continuous vendor oversight, secure software development, timely vulnerability remediation, and coordinated incident response throughout the education technology ecosystem as a whole. 

A continued pursuit of high-impact supply chain opportunities by threat actors will require strengthening third-party risk management and incorporating security into all phases of software development in order to protect educational continuity, safeguard sensitive data, and maintain trust across digital learning environments.

Threat Campaign Targets School Login Systems After Alleged Instructure Hack


 

The initial appearance of a routine service disruption within one of the most widely used academic learning platforms in the world quickly evolved into a significant cybersecurity issue as threat actors associated with the ShinyHunters group allegedly compromised Instructure's Canvas system. 

A large number of educational institutions experienced widespread operational instability as a result of the incident, which exposed sensitive academic and identity-related records, disrupted coursework timelines, and resulted in the defacement of several school authentication portals. 

A growing concern over the potential release of a data set reportedly affecting thousands of institutions as well as hundreds of millions of students and employees led Instructure to reveal that it had reached an agreement with the unauthorised actor responsible for the intrusion language that cybersecurity analysts interpreted as an indication of ransom negotiations. ShinyHunters collective claims to have successfully compromised Instructure's infrastructure for the second time in just a few weeks, further escalating the issue. 

The breach resulted in school authentication portals were made public and were affected in addition to backend systems. The incidents took place during final examination periods across several institutions using Canvas, causing even more disruption for administrators, educators, and students experiencing intermittent outages as a result of the earlier intrusion disclosed on April 30.

The Instructure platform had acknowledged that "criminal threat actors" were responsible for unauthorized access to parts of its environment, but subsequent activity indicates the attackers were still able to manipulate externally accessible services. 

When threat actors were reportedly injected malicious HTML components into Canvas login pages, unauthorized message prompts were found attributed to ShinyHunters, effectively defacing the authentication screens utilized for coursework management, assignment submissions, and academic communication, multiple Canvas login pages were later found displaying unauthorized messages attributed to ShinyHunters.

According to the message posted by the group, the allegedly stolen data will be made public on May 12 unless the company enters into a "settlement" negotiations. Parts of Instructure's online infrastructure appeared unstable during the escalation process, with some services intermittently returning "too many requests" errors while Canvas displayed maintenance notices indicating ongoing remediation and containment efforts throughout the company's network infrastructure. 

According to further disclosures, the breach affected a wide spectrum of academic stakeholders, including students, faculty, and institutional staff, with portions of information reportedly relating to minors. Despite Instructure's claims that passwords and highly sensitive authentication credentials were not compromised, the attackers are said to have obtained substantial amounts of information regarding personal identification and platform usage, such as usernames, e-mail addresses, student identification numbers, and private communications exchanged within the learning management system. 

According to the company, the initial compromise was terminated, remediation measures were implemented across the affected systems, and Canvas services were restored after containment procedures were initiated to prevent additional intrusions. However, ShinyHunters later stated it had successfully breached the platform again, this time targeting institution-specific authentication portals, thereby putting the company under pressure to enter into a settlement negotiation related to the earlier data theft, despite these efforts. 

As part of the extortion attempt, the group used stolen data as a means of coercion following network intrusions, which is a well-established operational pattern, however, the apparent recurrence of unauthorized access raised concerns regarding residual vulnerability issues within Instructure's network infrastructure. Canvas was brought offline once again following the second disruption, prompted the company to remove the component identified as being at the root of the incident  the Free-for-Teacher environment. 

Instructure acknowledged in an updated incident disclosure that investigators had identified a vulnerability associated with support ticket functionality within the Free-for-Teacher system, which threat actors allegedly exploited to facilitate the latest security breach. By putting the incident on its leak portal, ShinyHunters had earlier accepted public responsibility for the initial intrusion. 

The tactic is commonly used by ransomware and extortion-focused groups to increase pressure on targets by threatening data release under controlled circumstances. In the wake of the recent compromise, the attackers have attempted to reach out directly to media outlets regarding the defaced Canvas login pages, suggesting they are attempting to escalate the attack not only against Instructure but also against the thousands of educational institutions that rely on the platform for their operations. During ongoing negotiations regarding the previously stolen data, cybersecurity analysts viewed the public defacement as an attempt to amplify reputational and operational pressures. 

In spite of the fact that there is no clear indication of how the school-specific authentication pages were compromised, ShinyHunters officials have indicated the breach has been a separate one from the original attack, but declined to provide any further technical information regarding the method used to gain access to the system. 

The group claims to have stolen data from nearly 9,000 educational institutions around the world; these records are believed to belong to approximately 231 million people. Following the earlier compromise, the group claimed to have exfiltrated information related to nearly 9,000 educational institutions. 

A key component of the campaign was a mirroring of the threat group's established operating model, which is typically composed of a combination of network intrusion, public exposure of victims through leak sites, and sustained extortion efforts to maximize financial leverage following the theft of large amounts of data. There has been an increased focus on security architecture of cloud-based education platforms in the wake of the incident, which has become a critical infrastructure for academic operations worldwide.

In addition to disrupting coursework and institutional systems for the immediate period, the exposure of student communications and identity-linked records, particularly involving minors, demonstrates the long-term risks associated with large-scale compromises of digitally centralized learning environments. 

During the remediation and forensic investigation efforts, Instructure is likely to establish the breach as a landmark in the field of ransomware and extortion, which increasingly target educational technology ecosystems where operational urgency and reputational pressure can lead to high-stakes cybersecurity incidents.

Ransomware Attack Disrupts Grading Platform Used by LBUSD Cal State and LBCC


 

A cyberattack linked to the ShinyHunters extortion group temporarily disrupted educational operations across a number of educational institutions in the United States, causing concern over the potential exposure of sensitive student and faculty data. These institutions continued to restore access to Canvas this week. Although several universities and school districts have been able to resume normal access following recovery efforts coordinated by Canvas parent company Instructure, the incident continues to affect portions of the education sector. 

Administrators have assessed the broader impacts of the breach and reviewed claims regarding the compromise of data belonging to hundreds of millions of platform users around the world. After the incident was triggered on Thursday, teachers and students at Long Beach Unified School District, California State University Long Beach and Long Beach City College were suddenly unable to access Canvas, the cloud-based platform widely used for coursework, grades, assignments and internal communication, the operational impact of the incident became more apparent. 

According to district officials, they were informed earlier this week that Instructure, the company which provides Canvas, had discovered that certain user-identifying information related to customer environments had been accessed without authorization. In spite of the company's initial assertion that the incident had been contained and that core platform operations continued, educators later reported that login attempts redirected users to ransom-style messages allegedly associated with the ShinyHunters cybercriminal group upon attempting to log in.

Apparently, the notice instructed affected institutions to engage a cyber advisory firm and negotiate payment terms before a specified deadline otherwise compromised data could be exposed to the public. Despite the fact that the full extent of the intrusion is still under investigation, notifications sent to campus users indicate that names, email addresses, institutional identification numbers, and confidential communications may have been compromised. 

A response from Instructure was that portions of the platform environment had been disabled, the underlying vulnerability had been rectified, digital forensic specialists were engaged, and federal authorities, including the Federal Bureau of Investigation and the Cybersecurity and Infrastructure Security Agency, were coordinated. 

A significant number of academic institutions are experiencing the disruption at the same time, with final examinations at California State University Long Beach rapidly approaching. Since Canvas serves as the primary repository for instructional content, coursework, and student records, several educators have described the outage as operationally disrupting, even though some teachers have been able to maintain continuity by using externally hosted materials and collaboration tools through Google. 

Cybersecurity experts caution that, while the current incident has mainly disrupted colleges and universities, K-12 institutions have also faced repeated operational and data security challenges related to attacks against the education technology infrastructure. Researchers referred to the Los Angeles Unified School District cyberattack of 2022, when a ransomware-related intrusion disabled critical district systems over Labor Day weekend, disrupting internal communication, attendance tracking, and classroom instruction. 

Approximately 2,000 student assessment records, together with additional sensitive information, including driver’s license numbers and Social Security numbers accumulated over multiple years, were later published on the dark web as a result of the incident. Recovery efforts lasted for weeks during which administrative and technical staff restored systems and coordinated password resets for over 600,000 user accounts.

According to security researchers, incidents associated with platforms such as Canvas can create long-term phishing and social engineering risks even after services have been restored. A Norton security analyst, Luis Corrons, emphasized that information exposed by the company includes names, institutional email addresses, student identification numbers, and internal academic communications, which could provide threat actors with the necessary context to create highly convincing phishing campaigns impersonating legitimate school notifications regarding grades, coursework, financial aid, and password resets.

In addition to Anton Dahbura's concerns, the executive director of the Johns Hopkins University Information Security Institute advised institutions that residual risk may continue to exist after platform access has been restored, and cautioned against operating under this assumption. According to Dahbura, colleges and universities should encourage students and employees to change their passwords, review authentication tokens, and audit integrations with third-party platforms connected to Canvas environments. 

Likewise, colleges and universities should keep a close eye on follow-on phishing activity targeting them. Further, he emphasized that higher education is increasingly reliant on a single instructional platform, which represents a systemic risk as a whole. He advised academic institutions to develop resilience plans, implement additional security controls, and develop alternative instructional workflows that can support continuity during prolonged service interruptions. 

A centralized cloud-based learning infrastructure in the educational sector has further increased the cybersecurity vulnerability of the sector. As a result of a single third party platform compromise, thousands of academic institutions may be disrupted simultaneously if a single compromise occurs.

A continuing forensic investigation and recovery effort will require security teams on affected campuses to focus on credential protection, phishing monitoring, and access-review procedures, while assessing the degree of integration instructional platforms, such as Canvas, have made with broader institutional networks.

Medtronic Confirms ShinyHunters' Theft of 9 Million Records

 

Medtronic, a leading global medical device manufacturer, recently confirmed a significant cybersecurity breach affecting its corporate IT systems. The incident came to light after the notorious hacking group ShinyHunters claimed responsibility, boasting of stealing over 9 million records containing personally identifiable information (PII) and terabytes of internal corporate data. 

On April 17 and 18, 2026, the group listed Medtronic on its Tor-based data leak site, issuing a ransom ultimatum that expired on April 21 without public confirmation of payment or data release. Medtronic publicly disclosed the breach on April 24, 2026, via its website and a U.S. Securities and Exchange Commission Form 8-K filing, acknowledging unauthorized access but emphasizing that the intrusion was contained with no disruption to operations.

The breach targeted non-critical corporate networks, sparing patient-facing systems, medical devices, manufacturing, and distribution channels. Medtronic stated explicitly that products, patient safety, customer connections, financial reporting, and care delivery remained unaffected, as these operate on segregated infrastructure. ShinyHunters, known for high-profile extortion campaigns against over 40 organizations in 2026—including ADT, Amtrak, and Cisco—alleged the haul included sensitive PII from employees, partners, or affiliates, though Medtronic has not verified the exact volume or contents. The group's listing vanished from the leak site shortly after, fueling speculation of behind-the-scenes negotiations.

This incident underscores escalating threats to healthcare giants, where corporate IT often serves as a softer entry point for attackers. ShinyHunters has exploited misconfigured Salesforce Experience Cloud guest permissions in multiple cases, a customer setup issue rather than a platform flaw, according to Salesforce. Medtronic's response involved activating incident protocols with external cybersecurity experts to assess data exfiltration and potential exposure. An ongoing forensic investigation aims to pinpoint compromised information, with commitments to notify and support affected individuals if personal data is confirmed stolen.

The implications ripple beyond Medtronic, highlighting vulnerabilities in the medical technology sector amid rising ransomware and extortion tactics. Law firms like Schubert Jonckheer & Kolbe LLP launched investigations by early May 2026, probing liabilities for the nearly 9 million potentially impacted records. While no widespread data dumps have surfaced publicly, the breach erodes trust in supply chain security, even when clinical operations stay insulated. Healthcare firms face mounting pressure to fortify perimeter defenses as cybercriminals increasingly target administrative data for profit.

To mitigate risks from such incidents, individuals should monitor credit reports, enable two-factor authentication on personal accounts, and freeze credit if notified of exposure. Organizations are advised to segment networks rigorously, conduct regular penetration testing, patch third-party configurations like Salesforce promptly, and develop robust incident response plans. Medtronic's case reinforces the need for proactive cybersecurity hygiene to safeguard sensitive data in high-stakes industries.

Telus Digital Faces Scrutiny Following Claims of Large-Scale Data Extraction

 



Canadian outsourcing and digital services firm Telus Digital has confirmed that it experienced a cybersecurity incident after threat actors alleged they had extracted an enormous volume of data, estimated at nearly one petabyte, over a prolonged period of unauthorized access.

Telus Digital operates as the outsourcing and digital solutions division of Telus. The company provides services such as customer support, content moderation, artificial intelligence data operations, and other business process outsourcing functions to organizations around the world. Because firms in this sector often manage customer interactions, billing systems, and internal authentication tools on behalf of multiple clients, they are frequently targeted by attackers aiming to gain access to large datasets through a single compromise.

The breach has been linked to a threat group known as ShinyHunters, which claims it obtained a wide range of customer-related data connected to Telus Digital’s outsourcing services, along with call records tied to Telus’ consumer telecommunications operations.

Reports about a possible breach had surfaced earlier this year, and inquiries were made to the company at the time, though no response was received then. Telus has now acknowledged the incident, stating that it is investigating what information may have been accessed and which customers could be affected.

In its official statement, the company said unauthorized access was identified in a limited number of systems. It added that immediate steps were taken to contain the activity and prevent further intrusion. Telus also stated that its operations remain fully functional, with no evidence of disruption to customer connectivity or services. The company confirmed that external cyber forensics specialists have been engaged and that law enforcement authorities are involved. It further noted that additional safeguards have been implemented and that affected customers will be notified where appropriate.

Sources indicated that the attackers attempted to extort the company, but Telus did not engage in communication with them.


Attack Method and Data Exposure Claims

After learning that the company was not negotiating, the attackers were contacted for further details regarding the incident.

According to their claims, the intrusion began with access to Google Cloud Platform credentials that were previously exposed in data linked to the Salesloft Drift breach. In that earlier incident, attackers extracted Salesforce data belonging to approximately 760 organizations, including customer support tickets. These records were then examined to locate credentials, authentication tokens, and other sensitive information, which could be reused to access additional systems.

The threat actors stated that they identified credentials associated with Telus within that dataset. These credentials allegedly enabled them to access multiple internal systems, including a large BigQuery data environment. After extracting initial data, they reportedly used the tool trufflehog to scan for further secrets, allowing them to expand their access into additional parts of the company’s infrastructure.

The group claims that the total amount of data taken is close to one petabyte, though this figure has not been independently verified. They also shared the names of 28 well-known companies that they allege were affected. However, these claims have not been confirmed, and the identities of those organizations remain undisclosed.

The data described by the attackers covers a wide range of business operations. This includes information related to customer support services, call center activities, agent performance metrics, AI-powered support systems, fraud detection mechanisms, and content moderation processes. In addition, they claim to have accessed source code, financial records, Salesforce data, background verification documents, and recordings of customer service calls.

The breach is also said to affect Telus’ telecommunications operations, particularly its consumer fixed-line services. The allegedly exposed data includes detailed call logs, voice recordings, and campaign-related information. Samples of these call records reportedly contain timestamps, call durations, originating and receiving numbers, and technical metadata such as call quality indicators.

Overall, the nature of the exposed data appears to vary significantly depending on the organization, indicating that multiple business functions across different clients may have been impacted.

The attackers stated that they began extortion attempts in February, demanding $65 million in exchange for not releasing the stolen data. The company did not respond to these demands.

Telus has indicated that further updates may be provided as its investigation progresses.


Who Are ShinyHunters

The name ShinyHunters has been associated with various individuals and cyber incidents over time, but the group currently operating under this identity has emerged as one of the more active data extortion actors in recent months. Their operations have largely focused on compromising cloud-based platforms, particularly those connected to enterprise software ecosystems.

The group has been linked to incidents involving major organizations such as Google, Cisco, and Match Group, among others.

More recently, their tactics have expanded to include voice phishing, or vishing, attacks. In these cases, employees are contacted by individuals posing as IT support staff and are persuaded to reveal login credentials or multi-factor authentication codes through fraudulent websites. The group has also been observed using device code phishing techniques to obtain authentication tokens linked to identity platforms such as Microsoft Entra.

Once valid credentials and authentication codes are obtained, attackers can take control of single sign-on accounts and gain access to interconnected enterprise services, including Salesforce, Microsoft 365, Google Workspace, SAP, Slack, Adobe, Atlassian, Zendesk, and Dropbox.


Security Implications

This incident reflects a broader trend in which attackers reuse previously stolen data to launch new intrusions. It also highlights the elevated risk associated with outsourcing providers that centralize sensitive operations for multiple organizations.

Cybersecurity experts increasingly note that modern attacks often occur in stages, where one breach creates opportunities for subsequent compromises. As businesses continue to rely on cloud platforms and third-party service providers, the potential scale and impact of such incidents continue to grow.

The situation is currently under investigation, and additional verified details are expected as more information surfaces.

ShinyHunters Threatens Data Leak After Alleged Salesforce Breach

 

The hacking group ShinyHunters has warned roughly 400 companies that it may publish stolen data online if ransom demands are not met. The group claims it accessed private records through websites built on Salesforce Experience Cloud, a platform companies use to create public portals and customer support sites. 

According to earlier findings by cybersecurity firm Mandiant, the attackers targeted organisations that used Salesforce’s Experience Cloud for external-facing services such as help centres and information portals. 

How the breach allegedly happened? The reported intrusion appears linked to the configuration of public access settings within these websites. 

Salesforce allows websites built on Experience Cloud to include a “guest user” profile so visitors can view limited information without logging in. 

If these settings are configured too broadly, however, the access permissions can expose internal data to the public internet. Investigations suggest the attackers used a modified version of a tool called Aura Inspector to scan websites for such weaknesses. 

Once vulnerabilities were identified, the hackers were able to extract information including names and phone numbers. Security experts say the stolen data may already be fueling vishing attacks. 

In such scams, attackers contact employees by phone and attempt to trick them into revealing additional confidential information. 

Dispute over the root cause There is disagreement over whether the problem stems from a software flaw or from how companies configured their systems. Salesforce has said the platform itself remains secure and that the issue is related to customer settings rather than a vulnerability in the product. 

“Our investigation to date confirms that this activity relates to a customer-configured guest user setting, not a platform security flaw,” the company said in a blog post. 

ShinyHunters disputes that explanation, claiming it discovered a previously unknown flaw that allows it to bypass certain protections even on sites that appear properly configured. 

Independent researchers have not yet verified that claim. Pressure tactics used by hackers ShinyHunters is known for using aggressive extortion strategies to pressure victims into paying ransom demands. The group often releases stolen data in stages to increase pressure on organisations that refuse to negotiate. 

A recent example involved Dutch telecommunications provider Odido and its brand Ben. After the company declined to pay a ransom reportedly worth one million euros, the hackers began publishing large quantities of customer data on the dark web. 

Security guidance for companies Salesforce is urging customers to review their portal configurations and tighten access controls. The company recommends applying a “least privilege” approach, meaning guest users should only have the minimum permissions required to use a site. 

Businesses are also advised to keep data private by default, disable settings that expose internal staff information, and turn off public application programming interfaces where possible. 

These interfaces can allow external systems to exchange data and may create additional entry points if left open. 

The incident highlights the growing risks associated with misconfigured cloud services, which security analysts say have become a common target for cybercriminal groups seeking large volumes of corporate data.

Data Breach Data Leak Harvard Breach Upenn Hack ShinyHunters

ShinyHunters Leak Exposes Harvard and UPenn Personal Data

 

Hacking group ShinyHunters has reportedly published more than a million records stolen from Harvard University and the University of Pennsylvania (UPenn) on its dark web site, putting a vast trove of sensitive personal data within reach of cybercriminals worldwide. The leaked data appears to contain sensitive details about the students, employees, alumni, donors, and family members of the breached organizations. This has expanded the scope of the compromised data to a wide range of people. Initial verification of the leaked data has revealed that at least some of the leaked data is genuine. 

The UPenn breach is believed to have begun in early November 2025, when the hackers gained access to an employee’s single sign-on (SSO) account by claiming to have obtained full access to the UPenn employee’s SSO account. This has essentially turned the SSO account into a master key that has allowed the hackers to access the UPenn VPN system, Salesforce data, the Qlik analytics platform, SAP business intelligence tools, and SharePoint. During the course of the attack, the hackers also used the compromised login credentials to send offensive emails to 700,000 people. Initially, UPenn believed that the emails were fake, but they later turned out to be real.

Harvard confirmed a related compromise roughly three weeks after the UPenn disclosure, tying its own incident to a successful voice phishing (vishing) campaign. In this case, attackers are said to have infiltrated Alumni Affairs and Development systems, exposing data on past and present students, donors, some faculty and staff, and even spouses, partners, and parents of alumni and students. The stolen records reportedly include names, dates of birth, home addresses, phone numbers, estimated net worth, donation history, and sensitive demographic attributes such as race, religion, and sexual orientation.

Unlike traditional ransomware operations that both encrypt systems and steal data, ShinyHunters appears to have focused solely on data theft and extortion, deploying no encryptors in these campaigns. The group allegedly attempted to negotiate payment in cryptocurrency in exchange for promising to delete the stolen files, following the now-common double extortion model. When talks broke down and the universities did not pay, the hackers responded by dumping the data openly on their dark web leak site, amplifying the risk of identity theft, harassment, and targeted scams for victims.

For Harvard and UPenn, the breaches highlight the dangers of over-reliance on SSO accounts and human-centric weaknesses such as vishing, where convincing phone calls trick staff into revealing or approving access. For affected individuals, the publication of highly personal and demographic information raises concerns around fraud, doxxing, discrimination, and reputational harm that could persist for years. The incidents reinforce the need for stronger multifactor authentication, rigorous phishing and vishing awareness training, and tighter controls around high-value institutional accounts holding large volumes of sensitive data.
