TransUnion Data Breach Exposes Over 4 Million Customer Records

The FBI has issued an alert about two cybercriminal groups, UNC6040 and UNC6395, targeting Salesforce platforms for data theft and extortion. UNC6395 exploited compromised OAuth tokens for the Salesloft Drift application, while UNC6040 used vishing campaigns and modified Salesforce tools to breach Salesforce instances. Both groups have been active since at least October 2024, impacting multiple organizations. UNC6040 has been linked to extortion activities, with Google attributing these to a separate cluster, UNC6240, which has claimed to be the ShinyHunters group. The ShinyHunters group, along with Scattered Spider and LAPSUS$, recently announced they are going dark, but experts warn that the threat persists. UNC6040 impersonated corporate IT support personnel to gain access to Salesforce environments and used modified versions of Salesforce's Data Loader to exfiltrate data. Salesforce re-enabled integrations with Salesloft technologies, except for the Drift app, which remains disabled.

Plex has suffered a data breach, exposing customer authentication data. The breach included email addresses, usernames, and securely hashed passwords. Plex has advised users to reset their passwords, enable two-factor authentication (2FA), and sign out of all devices as a precaution. The breach did not include payment card information. Plex has addressed the vulnerability used in the breach but has not disclosed technical details. The company has also launched internal reviews to improve security and has advised users to be wary of potential phishing attacks. This is the second such incident affecting Plex users.

A supply chain attack compromised multiple npm packages with over 2.6 billion weekly downloads. Attackers injected malicious code into these packages after hijacking a maintainer's account via phishing. The malware targets web-based cryptocurrency transactions, redirecting them to attacker-controlled wallets. The attack was detected and mitigated by the NPM team, who removed the malicious versions within two hours. The phishing campaign targeted multiple maintainers, using a fake domain to trick them into updating their 2FA credentials. The malicious code operates by hooking into JavaScript functions and wallet APIs, intercepting and altering cryptocurrency transactions. The attack impacts users who installed the compromised packages during a specific time window and have vulnerable dependencies. The attack targeted Josh Junon, also known as Qix, who received a phishing email mimicking npm. The phishing email prompted the maintainer to enter their username, password, and 2FA token, which were stolen via an adversary-in-the-middle (AitM) attack. The attack affected 20 packages, including ansi-regex, chalk, debug, and others, with over 2 billion weekly downloads. The malware intercepts cryptocurrency transaction requests by computing the Levenshtein distance to swap the destination wallet address. The payload hooks into window.fetch, XMLHttpRequest, and window.ethereum.request, along with other wallet provider APIs. The attack also compromised another maintainer, duckdb_admin, to distribute the same wallet-drainer malware. The affected packages from the second maintainer include @coveops/abi, @duckdb/duckdb-wasm, and prebid, among others. The attack impacted roughly 10% of all cloud environments. The attackers diverted five cents worth of ETH and $20 worth of a virtually unknown memecoin. The attacker’s wallet addresses holding significant amounts have been flagged, limiting their ability to convert or use the funds.

Salesloft has taken Drift offline due to a security incident involving the theft of OAuth tokens and unauthorized access to Salesforce data. The breach began with the compromise of Salesloft's GitHub account, affecting multiple major tech companies, including Cloudflare, Google Workspace, PagerDuty, Palo Alto Networks, Proofpoint, SpyCloud, Tanium, Tenable, Zscaler, Tenable, Qualys, Rubrik, Spycloud, BeyondTrust, CyberArk, Elastic, Dynatrace, Cato Networks, and BugCrowd. The incident was attributed to a threat cluster tracked as UNC6395 and GRUB1. The breach occurred on September 5, 2025, affecting the marketing software-as-a-service product Drift. The attackers exploited vulnerabilities to steal authentication tokens, leading to unauthorized access to sensitive data. Salesloft has temporarily disabled Drift to conduct a comprehensive review and enhance security measures. The ShinyHunters extortion gang and threat actors claiming to be Scattered Spider were involved in the Salesloft Drift attacks, in addition to the previous Salesforce data theft attacks. The threat actors primarily focused on stealing support cases from Salesforce instances, which were then used to harvest credentials, authentication tokens, and other secrets shared in the support tickets. The threat actors' primary objective was to steal credentials, specifically focusing on sensitive information like AWS access keys, passwords, and Snowflake-related access tokens. The number of impacted companies has been updated to 29. Cloudflare disclosed that some customer support cases stored in Salesforce included configuration settings and 104 Cloudflare API tokens. Salesforce restored integration with the Salesloft platform, except for the Drift app, which remains disabled until further notice. The breach also affected Qantas, where executives had their short-term compensation reduced by 15% due to a data breach that impacted approximately 5.7 million passengers.

Bridgestone Americas, the North American division of Bridgestone Corporation, is investigating a cyberattack that has disrupted operations at all manufacturing facilities in North America. The attack, detected on September 2, 2025, affected facilities in Aiken County, South Carolina, and Joliette, Quebec. Bridgestone's rapid response reportedly contained the incident early, preventing customer data theft or extensive network infiltration. The company is working to mitigate the impact on its supply chain and ensure business continuity. The exact nature and scope of the cyber incident remain unknown.
