Massive Shai-Hulud Supply Chain Campaign Compromises npm Ecosystem, Including keyv and cacheable
The "Shai-Hulud" campaign (specifically the "ChainDrop" wave) is a sophisticated supply chain attack targeting the npm ecosystem via hijacked maintainer accounts for widely used packages like keyv and cacheable. Utilizing malicious npm preinstall scripts, the threat actor deploys a self-propagating "Mini Shai-Hulud" worm and an infostealer. The attack leverages OIDC provenance to bypass integrity checks and employs obfuscated JavaScript files, such as math_init.js and Math_Symbol.js, to exfiltrate AWS credentials, GitHub tokens, Kubernetes secrets, and CI/CD environment variables. With over 440 compromised packages and 2 billion monthly downloads at risk, the campaign facilitates deep transitive infection across developer workstations and cloud infrastructure.
Multi-Vector Supply Chain Campaign: Mastra AI, GitHub Actions, and Arch Linux AUR Compromise
A sophisticated supply chain campaign, attributed to the suspected threat actor TeamPCP, has simultaneously targeted the Mastra AI framework via npm, GitHub Actions CI/CD workflows, and the Arch Linux User Repository (AUR). The attack utilized dormant contributor account takeovers to poison the @mastra npm scope using the easy-day-js dependency and hijacked GitHub Action version tags to exfiltrate CI/CD credentials. Additionally, over 1,500 AUR packages were compromised with eBPF-based rootkit malware. This coordinated infrastructure, linked by the "Mini Shai-Hulud" worm, facilitates widespread code execution, credential theft, and persistent rootkit deployment across development, DevOps, and end-user Linux environments.
