Supply Chain Attack on npm Packages with Billions of Weekly Downloads

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 Disables Drift Following OAuth Token Theft

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.
