A new Rust-based supply chain malware, IronWorm, is targeting the Web3 ecosystem through malicious npm packages, according to SlowMist monitoring. The malware poses significant threats, including credential theft, wallet seed and password extraction, GitHub repository tampering, malicious package distribution, CI/CD secret leaks, Tor-based command control, and eBPF rootkit stealth. Security teams are advised to audit repositories for suspicious commits, unexpected build hooks, and automated identity submissions from tools like claude, dependabot, renovate, or github-actions. It is recommended to remove affected package versions, release clean versions, rotate all compromised keys and tokens, review GitHub Actions artifacts, and rebuild potentially compromised development or CI systems from clean images.
