Ledger Customer Data Exposed After Global-e Payment Processor Cloud Incident

 

A fresh leak of customer details emerged, linked not to Ledger’s systems but to Global-e - an outside firm handling payments for Ledger.com. News broke when affected users received an alert email from Global-e. That message later appeared online, posted by ZachXBT, a known blockchain tracker using a fake name, via the platform X. 

Unexpectedly, a breach exposed some customer records belonging to Ledger, hosted within Global-e’s online storage system. Personal details, including names and email addresses made up the compromised data, one report confirmed. What remains unclear is the number of people impacted by this event. At no point has Global-e shared specifics about when the intrusion took place.  

Unexpected behavior triggered alerts at Global-e, prompting immediate steps to secure systems while probes began. Investigation followed swiftly after safeguards were applied, verifying unauthorized entry had occurred. Outside experts joined later to examine how the breach unfolded and assess potential data exposure. Findings showed certain personal details - names among them - were viewed without permission. Contact records also appeared in the set of compromised material. What emerged from analysis pointed clearly to limited but sensitive information being reached. 

Following an event involving customer data, Ledger confirmed details in a statement provided to CoinDesk. The issue originated not in Ledger's infrastructure but inside Global-e’s operational environment. Because Global-e functions as the Merchant of Record for certain transactions, it holds responsibility for managing related personal data. That role explains why Global-e sent alerts directly to impacted individuals. Information exposed includes records tied to purchases made on Ledger.com when buyers used Global-e’s payment handling system. 

While limited to specific order-related fields, access was unauthorized and stemmed from weaknesses at Global-e. Though separate entities, their integration during checkout links them in how transactional information flows. Customers involved completed orders between defined dates under these service conditions. Security updates followed after discovery, coordinated across both organizations. Notification timing depended on forensic review completion by third-party experts. Each step aimed at clarity without premature disclosure before full analysis. 

Still, the firm pointed out its own infrastructure - platform, hardware, software - was untouched by the incident. Security around those systems remains intact, according to their statement. What's more, since users keep control of their wallets directly, third parties like Global-e cannot reach seed phrases or asset details. Access to such private keys never existed for external entities. Payment records, meanwhile, stayed outside the scope of what appeared in the leak. 

Few details emerged at first, yet Ledger confirmed working alongside Global-e to deliver clear information to those involved. That setup used by several retailers turned out to be vulnerable, pointing beyond a single company. Updates began flowing after detection, though the impact spread wider than expected across shared infrastructure. 

Coming to light now, this revelation follows earlier security problems connected to Ledger. Back in 2020, a flaw at Shopify - the online store platform they used - led to a leak affecting 270,000 customers’ details. Then, in 2023, another event hit, causing financial damage close to half a million dollars and touching multiple DeFi platforms. Though different in both scale and source, the newest issue highlights how reliance on outside vendors can still pose serious threats when handling purchases and private user information.  

Still, Ledger’s online platforms showed no signs of a live breach on their end, yet warnings about vigilance persist. Though nothing points to internal failures, alerts remind customers to stay alert regardless. Even now, with silence across official posts, guidance leans toward caution just the same.

California Privacy Regulator Fines Datamasters for Selling Sensitive Consumer Data Without Registration

 

The California Privacy Protection Agency (CalPrivacy) has taken enforcement action against Datamasters, a marketing firm operated by Rickenbacher Data LLC, for unlawfully selling sensitive personal and health-related data without registering as a data broker. The Texas-based company was found to have bought and resold information belonging to millions of individuals, including Californians, in violation of the California Delete Act. 

Under the Delete Act, companies engaged in buying or selling consumer data are required to register annually as data brokers by January 31. Beginning in 2026, the law will also enable consumers to use a centralized online tool known as the Delete Request and Opt-out Platform (DROP), which allows individuals to request the deletion of their personal information from all registered data brokers at once. 

CalPrivacy imposed a $45,000 fine on Datamasters for failing to register within the required timeframe. Due to the seriousness and continued nature of the violations, the agency also prohibited the company from selling personal information related to Californians. According to the regulator’s final order, Datamasters continued operating as an unregistered data broker despite repeated efforts by the agency to bring it into compliance. 

The investigation found that Datamasters purchased and resold data linked to people with specific medical conditions, including Alzheimer’s disease, drug addiction, and bladder incontinence, primarily for targeted advertising purposes. In addition to health data, the company traded consumer lists categorized by age and perceived race, marketing products such as “Senior Lists” and “Hispanic Lists.” The datasets also included information tied to political views, grocery shopping behavior, banking activity, and health-related purchases.  

The scope of the data involved was extensive, reportedly consisting of hundreds of millions of records containing names, email addresses, physical addresses, and phone numbers. CalPrivacy identified the nature and scale of the data processing as a significant risk to consumer privacy, particularly given the sensitive characteristics associated with many of the records. 

An aggravating factor in the case was Datamasters’ response to regulatory scrutiny. The company initially claimed it did not conduct business in California or handle data belonging to Californians. When confronted with evidence to the contrary, it later acknowledged processing such data and asserted that it manually screened datasets, a claim regulators found unconvincing. The agency noted that Datamasters resisted compliance efforts while continuing its data brokerage activities. 

As part of the enforcement order, signed on December 12, Datamasters was instructed to delete all previously acquired personal information related to Californians by the end of December. The company must also delete any California-related data it may receive in the future within 24 hours. Additionally, Datamasters is required to maintain compliance safeguards for five years and submit a report detailing its privacy practices after one year. 

In a separate action, CalPrivacy fined S&P Global Inc. $62,600 for failing to register as a data broker for 2024 by the January 31, 2025 deadline. The agency noted that the lapse, which lasted 313 days, was due to an administrative error and that the company acted promptly to correct the issue once identified.

DoorDash Data Breach Exposes Customer Information in October 2025 Incident

 

DoorDash has informed its customers that the company experienced a security incident in late October, marking yet another breach for the food delivery platform. According to details first reported by BleepingComputer, DoorDash has begun emailing users to disclose that on October 25, 2025, an unauthorized individual infiltrated parts of its internal systems and accessed selected customer contact information. The type of data exposed varied from person to person but involved key personal details. In its notification email, the company confirmed that names, physical addresses, phone numbers, and email addresses were among the information viewed by the intruder. While financial data does not appear to have been compromised, the collection of exposed fields still carries significant risk because such details can easily be reused in phishing, impersonation, and other forms of social engineering attacks. 

DoorDash stated that the root cause of the breach was a social engineering scam targeting an employee, which ultimately allowed the attacker to obtain credentials and slip past internal safeguards. As soon as the company recognized unusual activity, its security team revoked the unauthorized access, launched a broader investigation, and contacted law enforcement to support further review. However, the company did not specify how many individuals may have been affected. What is clear is that the impacted group includes customers, delivery drivers (known as Dashers), and merchants. Considering DoorDash reported roughly 7 million contractors in 2023, nearly 600,000 partner merchants in 2024, and more than 42 million active users, the number of people touched by the incident could be extensive. 

This latest breach adds to a concerning pattern for the company, which was previously affected by two significant incidents in 2019 and 2022. The 2019 attack exposed information belonging to approximately 5 million customers, Dashers, and merchants, while the 2022 event stemmed from the same campaign that targeted communications provider Twilio. These recurring issues highlight how attractive large consumer platforms remain to cybercriminals. 

For users, the most important step after any data exposure is to immediately update account passwords and ensure they are strong, unique, and not reused across services. A password manager can simplify this process and reduce risk over time. Enabling multi-factor authentication on DoorDash and other critical accounts adds an extra security barrier that often stops attackers even if credentials are stolen. Because personal details were accessed, users should stay alert for phishing messages that may imitate DoorDash or reference suspicious orders. These tactics are common after breaches and can easily lure people into clicking harmful links or providing additional sensitive information. 

Customers may also benefit from using reputable identity theft protection services that monitor financial activity and personal data for signs of misuse. While no single step can eliminate the consequences of a breach, proactive monitoring and cautious digital habits can significantly reduce the likelihood of further harm.

Asahi Group Confirms Ransomware Attack Disrupting Operations and Leaking Data

 

Japanese food and beverage conglomerate Asahi Group Holdings has confirmed that a ransomware attack severely disrupted its operations and potentially exposed sensitive data, including employee and financial information. The cyberattack, which occurred on September 29, 2025, forced the company to delay releasing its January–September financial results, originally scheduled for November 12. 

The attack paralyzed Asahi’s domestic order and shipment systems, halting automated operations across Japan. Despite the disruption, the company implemented manual order processing and resumed partial shipments to ensure a continued supply of its popular beverages and food products. 

The Qilin ransomware group has claimed responsibility for the breach, asserting that it stole over 9,300 files containing personal and financial data. On October 8, Asahi confirmed that some of the stolen data was found online, prompting a detailed investigation into the scope and type of compromised information. In a public statement, the company said it is working to identify affected individuals and will issue notifications once the investigation confirms unauthorized data transfer.  

Although the incident primarily impacted systems within Japan, Asahi stated there is no evidence of compromise affecting its global operations. 

Recovery efforts are steadily progressing. Asahi Breweries resumed production at all six of its factories by October 2, restoring shipments of Asahi Super Dry, with other product lines following soon after. Asahi Soft Drinks restarted production at six of its seven plants by October 8, while Asahi Group Foods has also resumed partial operations at all seven domestic facilities.  

However, Asahi’s systems have not yet been fully restored, and the company has not provided a definite recovery timeline. The ongoing disruption has delayed access to critical accounting systems, forcing a postponement of quarterly financial reporting. 

In its official statement, Asahi explained that the financial disclosure delay is necessary to ensure accuracy and compliance amid system recovery. The company issued an apology to shareholders and stakeholders for the inconvenience caused and promised transparent updates as investigations and remediation progress. 

The Asahi Group cyberattack serves as another reminder of the rising frequency and impact of ransomware incidents targeting major corporations worldwide.

Zimbra Zero-Day Exploit Used in ICS File Attacks to Steal Sensitive Data

 

Security researchers have discovered that hackers exploited a zero-day vulnerability in Zimbra Collaboration Suite (ZCS) earlier this year using malicious calendar attachments to steal sensitive data. The attackers embedded harmful JavaScript code inside .ICS files—typically used to schedule and share calendar events—to target vulnerable Zimbra systems and execute commands within user sessions. 

The flaw, identified as CVE-2025-27915, affected ZCS versions 9.0, 10.0, and 10.1. It stemmed from inadequate sanitization of HTML content in calendar files, allowing cybercriminals to inject arbitrary JavaScript code. Once executed, the code could redirect emails, steal credentials, and access confidential user information. Zimbra patched the issue on January 27 through updates (ZCS 9.0.0 P44, 10.0.13, and 10.1.5), but at that time, the company did not confirm any active attacks. 

StrikeReady, a cybersecurity firm specializing in AI-based threat management, detected the campaign while monitoring unusually large .ICS files containing embedded JavaScript. Their investigation revealed that the attacks began in early January, predating the official patch release. In one notable instance, the attackers impersonated the Libyan Navy’s Office of Protocol and sent a malicious email targeting a Brazilian military organization. The attached .ICS file included Base64-obfuscated JavaScript designed to compromise Zimbra Webmail and extract sensitive data. 

Analysis of the payload showed that it was programmed to operate stealthily and execute in asynchronous mode. It created hidden fields to capture usernames and passwords, tracked user actions, and automatically logged out inactive users to trigger data theft. The script exploited Zimbra’s SOAP API to search through emails and retrieve messages, which were then sent to the attacker every four hours. It also added a mail filter named “Correo” to forward communications to a ProtonMail address, gathered contacts and distribution lists, and even hid user interface elements to avoid detection. The malware delayed its execution by 60 seconds and only reactivated every three days to reduce suspicion. 

StrikeReady could not conclusively link the attack to any known hacking group but noted that similar tactics have been associated with a small number of advanced threat actors, including those linked to Russia and the Belarusian state-sponsored group UNC1151. The firm shared technical indicators and a deobfuscated version of the malicious code to aid other security teams in detection efforts. 

Zimbra later confirmed that while the exploit had been used, the scope of the attacks appeared limited. The company urged all users to apply the latest patches, review existing mail filters for unauthorized changes, inspect message stores for Base64-encoded .ICS entries, and monitor network activity for irregular connections. The incident highlights the growing sophistication of targeted attacks and the importance of timely patching and vigilant monitoring to prevent zero-day exploitation.

Telstra Denies Scattered Spider Data Breach Claims Amid Ransom Threats

 

Telstra, one of Australia’s leading telecommunications companies, has denied claims made by the hacker group Scattered Spider that it suffered a massive data breach compromising nearly 19 million personal records. The company issued a statement clarifying that its internal systems remain secure and that the data in question was scraped from publicly available sources rather than stolen. In a post on X (formerly Twitter), Telstra emphasized that no passwords, banking details, or sensitive identification data such as driver’s licenses or Medicare numbers were included in the dataset. 

The claims originated from a dark web post published on October 3 by a group calling itself Scattered Lapsus$ Hunters, an offshoot of Scattered Spider. The group alleged it had stolen more than 100GB of personally identifiable information, including names and physical addresses, and warned that company executives should negotiate to avoid further data exposure. The attackers claimed the alleged breach took place in July 2023 and threatened to release the data publicly if a ransom was not paid by October 13, 2025. They also asserted possession of over 16 million records contained in a file named telstra.sql, which they said was part of a larger collection of 19 million records. 

In a surprising twist, the ransom note also mentioned Salesforce, the global cloud computing company, demanding negotiations begin with its executives. Salesforce swiftly rejected the demand, issuing a statement on October 8 declaring that it “will not engage, negotiate with, or pay any extortion demand,” aligning with global cybersecurity guidelines that discourage ransom payments. 

Scattered Lapsus$ Hunters has made similar claims about breaches involving several major corporations, including Qantas, IKEA, and Google AdSense. Cybersecurity intelligence platforms like Cyble Vision have documented multiple previous instances of alleged Telstra data breaches, some dating back to 2022. In one notable case, a threat actor called UnicornLover67 claimed to possess a dataset containing over 47,000 Telstra employee records, including email addresses and hashed passwords. Telstra has previously confirmed smaller breaches linked to third-party service providers, most recently in 2022, affecting around 132,000 customers. 

However, cybersecurity analysts remain uncertain whether the current claims represent a fresh breach or a recycling of old data. Experts suggest that previously leaked or publicly available datasets may have been repurposed to appear as new evidence of compromise. This possibility aligns with Telstra’s statement that no recent intrusion has occurred. 

The investigation into the alleged breach remains ongoing as the ransom deadline approaches. While Telstra continues to assert that its systems are uncompromised, the persistence of repeated breach claims underscores the growing challenge of misinformation and data reuse in the cybercrime landscape. The Cyber Express has reached out to Telstra for further updates and will continue to monitor the situation as new details emerge.

Insight Partners Ransomware Attack Exposes Data of Thousands of Individuals

 

Insight Partners, a New York-based venture capital and private equity firm, is notifying thousands of individuals that their personal information was compromised in a ransomware attack. The firm initially disclosed the incident in February, confirming that the intrusion stemmed from a sophisticated social engineering scheme that gave attackers access to its systems. Subsequent investigations revealed that sensitive data had also been stolen, including banking details, tax records, personal information of current and former employees, as well as information connected to limited partners, funds, management companies, and portfolio firms. 

The company stated that formal notification letters are being sent to all affected parties, with complimentary credit monitoring and identity protection services offered as part of its response. It clarified that individuals who do not receive a notification letter by the end of September 2025 can assume their data was not impacted. According to filings with California’s attorney general, which were first reported by TechCrunch, the intrusion occurred in October 2024. Attackers exfiltrated data before encrypting servers on January 16, 2025, in what appears to be the culmination of a carefully planned ransomware campaign. Insight Partners explained that the attacker gained access to its environment on or around October 25, 2024, using advanced social engineering tactics. 

Once inside, the threat actor began stealing data from affected servers. Months later, at around 10:00 a.m. EST on January 16, the same servers were encrypted, effectively disrupting operations. While the firm has confirmed the theft and encryption, no ransomware group has claimed responsibility for the incident so far. A separate filing with the Maine attorney general disclosed that the breach impacted 12,657 individuals. The compromised information poses risks ranging from financial fraud to identity theft, underscoring the seriousness of the incident. 

Despite the scale of the attack, Insight Partners has not yet responded to requests for further comment on how it intends to manage recovery efforts or bolster its cybersecurity posture going forward. Insight Partners is one of the largest venture capital firms in the United States, with over $90 billion in regulatory assets under management. Over the past three decades, it has invested in more than 800 software and technology startups globally, making it a key player in the tech investment ecosystem. 

The breach marks a significant cybersecurity challenge for the firm as it balances damage control, regulatory compliance, and the trust of its investors and partners.

GitHub Supply Chain Attack ‘GhostAction’ Exposes Over 3,000 Secrets Across Ecosystems

 

A newly uncovered supply chain attack on GitHub, named GhostAction, has compromised more than 3,300 secrets across multiple ecosystems, including PyPI, npm, DockerHub, GitHub, Cloudflare, and AWS. The campaign was first identified by GitGuardian researchers, who traced initial signs of suspicious activity in the FastUUID project on September 2, 2025. The attack relied on compromised maintainer accounts, which were used to commit malicious workflow files into repositories. These GitHub Actions workflows were configured to trigger automatically on push events or manual dispatch, enabling the attackers to extract sensitive information. 

Once executed, the malicious workflow harvested secrets from GitHub Actions environments and transmitted them to an attacker-controlled server through a curl POST request. In FastUUID’s case, the attackers accessed the project’s PyPI token, although no malicious package versions were published before the compromise was detected and contained. Further investigation revealed that the attack extended well beyond a single project. Researchers found similar workflow injections across at least 817 repositories, all exfiltrating data to the same domain. To maximize impact, the attackers enumerated secret variables from existing legitimate workflows and embedded them into their own files, ensuring multiple types of secrets could be stolen. 

GitGuardian publicly disclosed the findings on September 5, raising issues in 573 affected repositories and notifying security teams at GitHub, npm, and PyPI. By that time, about 100 repositories had already identified the unauthorized commits and reverted them. Soon after the disclosures, the exfiltration endpoint used by the attackers went offline, halting further data transfers. 

The scope of the incident is significant, with researchers estimating that roughly 3,325 secrets were exposed. These included API tokens, access keys, and database credentials spanning several major platforms. At least nine npm packages and 15 PyPI projects remain directly affected, with the risk that compromised tokens could allow the release of malicious or trojanized versions if not revoked. GitGuardian noted that some companies had their entire SDK portfolios compromised, with repositories in Python, Rust, JavaScript, and Go impacted simultaneously. 

While the attack bears some resemblance to the s1ngularity campaign reported in late August, GitGuardian stated that it does not see a direct connection between the two. Instead, GhostAction appears to represent a distinct, large-scale attempt to exploit open-source ecosystems through stolen maintainer credentials and poisoned automation workflows. The findings underscore the growing challenges in securing supply chains that depend heavily on public code repositories and automated build systems.

Dark Web Data Breach data security Data Theft Discord Discord Users leaked sensitive data personal data security Personal Information

Nearly Two Billion Discord Messages Scraped and Sold on Dark Web Forums

 

Security experts have raised alarms after discovering that a massive collection of Discord data is being offered for sale on underground forums. According to researchers at Cybernews, who reviewed the advertisement, the archive reportedly contains close to two billion messages scraped from the platform, alongside additional sensitive information. The dataset allegedly includes 1.8 billion chat messages, records of 35 million users, 207 million voice sessions, and data from 6,000 servers, all available to anyone willing to pay. 

Discord, a platform widely used for gaming, social communities, and professional groups, enables users to connect via text, voice, and video across servers organized around different interests. Many of these servers are open to the public, meaning their content—including usernames, conversations, and community activity—can be accessed by anyone who joins. While much of this information is publicly visible, the large-scale automated scraping of data still violates Discord’s Terms of Service and could potentially breach data protection regulations such as the EU’s General Data Protection Regulation (GDPR) or California’s Consumer Privacy Act (CCPA).

The true sensitivity of the dataset remains unclear, as no full forensic analysis has been conducted. It is possible that a significant portion of the messages and voice records were collected from publicly accessible servers, which would reduce—but not eliminate—the privacy concerns. However, the act of compiling, distributing, and selling this information at scale introduces new risks, such as the misuse of user data for surveillance, targeted phishing, or identity exploitation. 

Discord has faced similar challenges before. In April 2024, a service known as Spy.Pet attempted to sell billions of archived chat logs from the platform. That operation was swiftly shut down by Discord, which banned the associated accounts and confirmed that the activity violated its rules. At the time, the company emphasized that automated scraping and self-botting were not permitted under its Terms of Service and stated it was exploring possible legal action against offenders. 

The recurrence of large-scale scraping attempts highlights the ongoing tension between the open nature of platforms like Discord and the privacy expectations of their users. While public servers are designed for accessibility and community growth, they can also be exploited by malicious actors seeking to harvest data en masse. Even if the information being sold in the latest case is largely public, the potential to cross-reference user activity across communities raises broader concerns about surveillance and abuse. 

As of now, Discord has not issued an official statement on this latest incident, but based on previous responses, it is likely the company will take steps to disrupt the sale and enforce its policies against scraping. The incident serves as another reminder that users on open platforms should remain mindful of the visibility of their activity and that service providers must continue to balance openness with strong protections against data misuse.

141M Files Analyzed: Alarming New Report Reveals True Scale and Impact of Data Breach

 

A comprehensive new study analyzing over 141 million files from 1,297 ransomware and data breach incidents has shed disturbing light on the real risks of modern cyberattacks—particularly the overlooked threat of unstructured data. The research, conducted by cybersecurity firm Lab 1, is being termed the “biggest ever content-level analysis of breached datasets” and offers deep insights into the fallout of these breaches.

While the total number of files may not seem extraordinary when compared to criminal databases boasting 16 billion credentials or the recent exposure of 184 million plaintext passwords, it’s the content of these files that makes this report especially urgent.

According to Robin Brattel, CEO of Lab 1, unlike most analyses that focus on structured data like login credentials, this report examined unstructured files, often housing highly sensitive information. “The analysis focused on the huge risks associated with unstructured files that often hold high-value information, such as cryptographic keys, customer account data, or sensitive commercial contracts,” Brattel noted.

The findings are staggering:

  1. Financial documents were present in 93% of incidents and made up 41% of all files analyzed.
  2. 49% of breaches contained bank statements, and 36% included International Bank Account Numbers (IBANs).
  3. 14% involved wealth statements, and 82% of breaches exposed personal or corporate identifiable information (PII).
  4. 67% of that breached PII came from customer service interactions.
  5. 51% included email leaks that exposed U.S. Social Security numbers.
  6. On average, 54 email addresses were compromised per breach.
  7. Cryptographic keys were discovered in 18% of incidents, with code files accounting for 17%.
  8. System logs appeared in 79%, and images in 81% of cases.

The average breach, according to Lab 1, contains 22,647 files and 13.44 GB of data, with 14 different file types and 22 classifications. Most alarmingly, each breach impacts an average of 482 organizations, demonstrating the far-reaching “blast radius” of cyber incidents.

The report explains that this blast radius has grown 61% over the past three years, significantly increasing systemic risk, regulatory exposure, and reputational damage. Many affected entities are nth-party connections in the supply chain—organizations completely unaware of their data exposure.

In extreme cases, the number of impacted organizations reached 1.73 million in a single breach, while the financial services sector saw an average impact of 4,468 organizations per breach.

As Damian Sutcliffe, former CIO (EMEA) at Goldman Sachs, warns: “We need to stop thinking of breaches as isolated incidents… [the risk] applies to not just that held within our systems, but information held across our entire supply chain.”

Another recent study—the 2025 Ransomware Report by Zscaler ThreatLabz—reinforces these concerns. Deepen Desai, executive VP of cybersecurity at Zscaler, noted a shift in tactics: “Ransomware tactics continue to evolve, with the growing shift toward extortion over encryption as a clear example.” The use of GenAI by attackers has further amplified the threat, enabling more targeted and efficient breaches.

The Zscaler report found:

  • A 146% year-over-year surge in ransomware attacks blocked by its cloud platform.
  • A 92% increase in exfiltrated data volume among the top 10 ransomware groups.
  • Total data stolen rose from 123 TB to 238 TB in just one year.

This escalating trend shows that ransomware is no longer just about locking systems—it’s about weaponizing stolen data.

As cybercriminals increasingly behave like data scientists, capable of mining massive datasets for exploitable intelligence, the need to secure not just networks, but also the unstructured data within them, has never been more critical.
