Tensorlake npm SDK Compromised to Deliver Shai-Hulud Credential-Stealing Worm
Version 0.5.144 of the "tensorlake" npm SDK — used for Tensorlake AI agent sandboxes and cloud services — was compromised in a ChainDrop/Shai-Hulud supply chain attack. Socket found an obfuscated preinstall worm that harvests npm, GitHub, AWS, Kubernetes, Vault and SSH credentials, plus MCP and AI coding tool config files for Claude, Cursor, Kiro, Windsurf and Zed. It establishes persistence, executes remotely supplied code, and republishes itself via the victim's publishing identity.
Stolen API tokens and MCP configuration files turn one poisoned dependency into broad API and agent-infrastructure access. Teams need visibility into which APIs and agent credentials are reachable after such compromises.
