AI Ransomware Autonomous AI Agent Cloud Security CVE-2025-3248 Cyber Threats JadePuffer Ransomware Langflow Vulnerability LLM security Ransomware Attack

JadePuffer Uses AI to Streamline End to End Ransomware Operations


 

Researchers have discovered the first ransomware intrusion conducted almost entirely by an autonomous large language model (LLM) agent, further demonstrating how generative AI and cybercrime are convergent. 

Sysdig researchers were able to detect the campaign by analyzing an attack linked to the JadePuffer threat actor that exploited a critical vulnerability in Langflow to gain initial access. Following reconnaissance, credential harvesting, privilege escalation, lateral movement, persistence, and encryption of data, an AI agent was able to conduct these activities independently. 

Instead of operating as a scripted automation tool, the agent demonstrated an ability to assess its environment, recover from failed actions, and dynamically adjust its approach throughout the intrusion, which highlights a significant shift toward AI-assisted offensive operations with minimal direct human intervention.

During the intrusion, CVE-2025-3248 was exploited, which was a critical unauthenticated remote code execution vulnerability in Langflow that enabled arbitrary Python code execution when the deployment was exposed to the internet. Although patched in April and later added to CISA's Known Exploited Vulnerabilities catalog following active exploitation, internet-exposed Langflow instances remained attractive targets because they commonly stored cloud credentials, API tokens, and application secrets. 

The AI-driven operation then systematically extracted Langflow's PostgreSQL database and profiled the compromised host before expanding its reconnaissance to connected MinIO object storage, enumerating environment variables and sensitive configuration files, and harvesting available credentials. When an API returned XML instead of the expected JSON, the agent automatically adjusted its parsing logic and continued enumeration without manual intervention. 

The operation also established persistence through a cron job configured to contact attacker-controlled infrastructure every 30 minutes. Once persistence and reconnaissance were established, the AI agent moved to the destructive phase of the attack by dynamically refining its execution in response to its environment of target. 

A Sysdig analysis found that the ransomware model modified payloads to satisfy authentication checks, verified that User Defined Functions (UDFs) were present, and signaled that work had been completed before initiating ransomware activity. By using MySQL's AES_ENCRYPT() function, all 1,342 Nacos service configuration records were encrypted, the original configuration_info and history tables were removed, and a README_RANSOM table was created containing the extortion message, Bitcoin payment address, and Proton Mail contact information for negotiations. 

Although the ransom note claimed AES-256 encryption, Sysdig assessed the implementation more closely resembled AES-128 in ECB mode. In addition, the encryption key was generated locally, but was neither retained nor transmitted to attackers' infrastructure.

The researchers also noted the Bitcoin wallet embedded in the ransom instructions matched a public documentation address, suggesting that the LLM reproduced this address from its training data rather than generating an operational payment destination for the ransom. Each captured payload included an explanation in natural language explaining how the actions were carried out, demonstrating the agent's ability to interpret system feedback, diagnose errors, and revise its logic, rather than relying on repetitive scripted retries, throughout the intrusion.

Aside from rapid troubleshooting execution failures, Sysdig also documented the agent's ability to interpret error responses and alter its approach in real time. The model was observed to correct an unsuccessful authentication attempt within 31 seconds by identifying the root cause of the failure rather than repeating the same steps over and over again. There were over 600 distinct payloads recorded throughout the intrusion, which each reflected deliberate progression through sequential attack stages rather than static automation. 

A Bitcoin wallet incorporated into the ransom note was an unresolved anomaly, which precisely matched an address published in Bitcoin developer documentation, an address which is well known for its use. 

Investigators were unable to determine whether the address was reproduced from the training data or if it was deliberately selected by the operator since both references are readily available in technical resources. It is also indicative of a larger evolution in cyber operations assisted by artificial intelligence during the past year. Earlier claims of AI-powered ransomware, including PromptLock, were ultimately linked to controlled research rather than active criminal operations. 

The use of generative artificial intelligence in operational situations has become increasingly evident in recent incidents. Anthropic previously disclosed the use of its Claude Code assistant in extortion against at least 17 organizations under human supervision in an extortion campaign, followed by a largely autonomous state-linked espionage operation using artificial intelligence to develop exploits and facilitate data theft. 

Operator involvement was limited. Similar fabricated credentials were also observed in the JadePuffer campaign, reinforcing the possibility that the unusual Bitcoin addresses observed may have been the result of model hallucinations rather than deliberate malicious intent. Collectively, these incidents demonstrate the ways in which artificial intelligence is automating discrete phases of sophisticated intrusion, reducing the expertise and effort normally required to conduct large-scale offensive operations. 

From a defensive perspective, Sysdig recommends maintaining established security practices. Langflow deployments should be fully patched against CVE-2025-3248 and code execution interfaces should not be exposed directly to the internet. Secrets should be stored in dedicated secrets managers rather than accessible runtime environments. Additionally, the company recommends replacing default signing keys, restricting public exposure, preventing database connections from root accounts, as well as enforcing outbound network controls so that compromised hosts are not able to communicate with command and control systems.

According to Sysdig, autonomous agents are able to detect and exploit new vulnerabilities within hours of their disclosure, which makes runtime detection and behavioral monitoring equally critical as timely patch management.

It was reported by the researchers that indicators of compromise associated with the campaign were released in support of incident response efforts, including the use of CVE-2025-3248 as the initial entry vector, command-and-control infrastructure located at 45.131.66[.]106 with an ongoing beacon program, and a staging server located at 64.20.53[.]230. There are three ransom artifacts associated with the ransom attack, namely the table README_RANSOM, the wallet 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy, and the email address e78393397[@]proton[.]me. 

JadePuffer is not regarded by Sysdig as introducing fundamentally new attack techniques, but the researchers consider it to be an important indicator of where offensive capabilities are heading. Creating an environment where autonomous AI agents can individually combine familiar exploitation methods into complete intrusion chains, making every exposed application server, configuration repository, and administrative interface available to the internet a far more attractive target than before. 

The evolution of ransomware has reached an important turning point with the launch of JadePuffer, as autonomous artificial intelligence agents are now capable of executing complex attacks without human assistance. 

AI infrastructure should be secured, credentials exposed to the internet must be rigorously managed, and runtime detection capabilities should be strengthened to identify adaptive behavior before it progresses into a full-scale compromise. With artificial intelligence-assisted attacks on the rise, proactive resilience is as important as rapid patching.

Ransomware Attack
Cybersecurity Incident Dark Web Leak Data Extortion Data Leak financial data exposure Information Security MyPillow Data Breach Play Ransomware Ransomware Attack

MyPillow Hit by Ransomware Attack as Cyber Threats Intensify


 

MyPillow, a Minnesota-based bedding manufacturer founded by Mike Lindell, has been targeted by a ransomware group. This adds the company to a growing list of organizations that are currently under cyber extortion threats. As a result of the unauthorized access to a broad range of sensitive corporate and personal records, identified as Play, the threat actor claims that payroll data, financial information, tax information, identification information, and internal business files have been exfiltrated. 

The claims have attracted attention due to the sensitive nature of the alleged exposed data, even though Lindell has denied the allegations and described them as politically motivated. As a result of this incident, the risks associated with modern ransomware campaigns are evolving, resulting from increased data theft and public exposure, which often accompany or replace traditional file encryption methods. 

MyPillow has become increasingly aware that its network has been compromised and its company data has been stolen as further details emerge from the alleged intrusion. It was reported that CEO Mike Lindell dismissed the claims when they first emerged in May 2025, however, the threat actors later released approximately 9.8 gigabytes of data via a dark-web leak portal, a tactic commonly used to pressure organizations unwilling to negotiate ransom. 

There are 11,456 files reported in the dataset dating from 2011 through 2026, indicating that historical records of the company have been preserved alongside more recent information about the company. This exposure indicates that the attackers obtained sensitive operational data, including payroll records and financial transactions, indicating the potential depth of the compromise, as well as raising further concerns about how long unauthorised access will remain within the company's network. 

Play's dark-web leak portal revealed the allegations of MyPillow, listing the company among its claimed victims and setting a deadline for public release of purportedly stolen information if ransom negotiations failed. The allegations gained further visibility when MyPillow appeared there. Ransomware operations are evolving in a broader sense, with attackers increasingly stealing data and threatening to publish it, as opposed to relying solely on file encryption to threaten victims.

In the ransomware ecosystem, data-centric extortion tactics are becoming increasingly popular. Modern threat groups increasingly prioritize stealing sensitive information over system encryption as a means of disrupting business operations. By leveraging the threat of public disclosure, they are exerting pressure on victims by leveraging the theft of sensitive information. By adopting this approach, organisations become more vulnerable to reputational damage, regulatory scrutiny, legal liabilities, and heightened concerns about employee and customer privacy as a result of an incident. 

The lack of verification can lead to unverified claims of data compromise quickly escalating to a broader business risk, prompting questions about the security posture of the organization and the integrity of data that has been entrusted to it from stakeholders, partners, insurers, and regulators. In addition to the nature of the alleged cyber intrusion, the incident has gained heightened public attention as a result of the company's and its leadership's high profile. 

During Mike Lindell's tenure, MyPillow has grown beyond its flagship bedding products to include mattresses, linens, bath products, nutritional supplements, coffee, and snacks. Since Lindell is a political activist and continues to promote disputed claims regarding the 2020 U.S. presidential election, MyPillow's public profile extends beyond retail. These claims have resulted in multiple legal challenges, making any major development involving the company likely to be of interest to individuals outside the cybersecurity community as well. 

The consequences of such an unverified claim of data compromise are that it quickly escalates into a broader business risk, causing stakeholders, partners, insurers, and regulators to inquire about the organization's security posture and the integrity of data entrusted to it. Due to the nature of the alleged cyber intrusion as well as the profile of the company and its management, the incident has heightened public attention. 

Since Mike Lindell has become President of MyPillow, it has expanded its product line beyond its bedding offerings to encompass mattresses, linens, bath products, nutritional supplements, coffee, and snack items. Due to Lindell's political activism and ongoing promotion of disputed claims surrounding the 2020 United States presidential election, MyPillow's public profile has extended beyond retail. 

A number of legal challenges have been brought against the company for these claims, making any major development involving the company likely to draw attention from outside the cybersecurity community as well. 

According to Lindell, political controversy has negatively impacted MyPillow's business, indicating that independent assessments have estimated an estimated $400 million in losses to the company and brand. Additionally, Lindell indicated that he plans to seek compensation through President Donald Trump's recently instituted $1.8 billion Anti-Weaponization Fund, an initiative that has become the subject of political debate and controversy. 

Since several years, MyPillow has had financial difficulties, particularly after major retailers, including Walmart, Kohl's, J.C. Penney, Wayfair, and Bed Bath & Beyond, removed its products from their shelves as a result of the events surrounding January 6. While Lindell has maintained that these decisions were politically motivated, several retailers have indicated that declining consumer demand played a significant role in these decisions. Due to this, the ransomware claims are coming at a time when the company is already confronting legal disputes, reputational pressure, and broader political controversy. 

The ten candidates who seek the Republican nomination to run for Minnesota’s gubernatorial office include Lindell, who will face Senator Amy Klobuchar as the Democratic frontrunner after Governor Tim Walz has decided not to seek another term. 

Based on the information reportedly exposed through the leak, it appears as though access has been gained to some of the company's most important financial and personnel records. It is believed that the breach resulted in the theft of Social Security numbers, tax documentation including W-9 and 1099 forms, payroll records containing employee contact information, bank statements, wire transfer documentation, American Express account statements, vendor billing records, advertising expenditure reports, internal audit documents, budgeting materials from the corporation, and even aviation-related expense logs associated with private aircraft operations. 

From a data security and compliance perspective, the breadth of the dataset indicates that the attackers may have accessed systems that contained both administrative and operational information, thus increasing the severity of the incident. 

From a data security and compliance perspective, MyPillow has not disclosed how many people were potentially affected, whether external incident-resolution specialists were consulted, or whether identity theft protection services were offered to the affected. It remains unclear, therefore, how the breach was disclosed, how notifications were carried out, and how the company is conducting remediation efforts.

In addition to the immediate allegations, this incident illustrates an important aspect of cybercrime: access to sensitive information has become just as valuable to threat actors as access to systems. In this case, it is likely that the outcome will be determined not only by what was accessed, but also by what was disclosed.

Canvas LMS Data Breach Instructure Breach Login Page Defacement Ransomware Attack School Cyberattack ShinyHunters

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.

Academic Network Security Canvas cyberattack Data Breach Education Sector Security Phishing Threats Ransomware Attack ShinyHunters

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.
