Malicious code in @antv/gi-assets-janusgraph (npm)

The npm account `atool` was compromised and used to publish 631 malicious versions across 314 npm packages, including @antv/gi-assets-janusgraph, in an automated 22-minute burst. Each malicious version injects a preinstall hook executing an obfuscated Bun script that exfiltrates credentials and establishes persistence via CI/CD workflow injection and system daemons.

  • @antv/gi-assets-janusgraphMalicious preinstall hook injected; part of Mini Shai-Hulud campaign

A threat actor compromised the npm account atool and published 631 malicious versions across 314 npm packages as part of the "Mini Shai-Hulud" supply chain attack campaign. The attack occurred in an automated 22-minute burst, with @antv/gi-assets-janusgraph among the affected packages.

Each malicious version injects a preinstall hook that executes a 498KB obfuscated Bun script. The script uses the GitHub API as a covert exfiltration channel to steal credentials including AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes service account tokens, SSH keys, Docker auth configs, database connection strings, Stripe keys, and Slack tokens. Stolen credentials are committed to attacker-controlled repositories following Dune-themed naming patterns (e.g., harkonnen-melange-742).

Beyond credential theft, the malicious payload establishes persistence through multiple mechanisms: CI/CD workflow injection (a GitHub Actions workflow named Run Copilot that dumps all secrets via toJSON(secrets)), AI agent session hooks, and a system daemon named kitty-monitor. The compromise was confirmed by both Amazon Inspector and Google Open Source Security sources.

Indicators of compromise

Packages
  • @antv/gi-assets-janusgraph

Remediation

  • Immediately audit and rotate all credentials (AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes tokens, SSH keys, Docker configs, database credentials, Stripe keys, Slack tokens) that may have been exposed
  • Remove all malicious versions of affected packages from npm; update to patched versions if available
  • Scan CI/CD systems for injected GitHub Actions workflows named 'Run Copilot' or similar and remove them
  • Search systems for the 'kitty-monitor' daemon and remove it
  • Review git commit history in attacker-controlled repositories with Dune-themed names for exfiltrated data
  • Implement package signature verification and integrity checks for npm dependencies
  • Monitor for suspicious preinstall hooks in package.json files across the supply chain
