A critical malware incident was identified in the gitlens npm package. According to the GitHub Security Advisory (GHSA-mgwg-48mg-h7pg), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers be rotated immediately from a different, uncompromised system. While the package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning removal of the package alone may not eliminate all malicious software that resulted from the installation.\n\nThis represents a critical supply chain compromise affecting the npm ecosystem.

Indicators of compromise

Remediation

  • Conduct a full security audit of any system that had gitlens installed
  • Consider the affected system(s) as potentially fully compromised and plan for complete rebuild if critical systems are involved
  • Check for any unauthorized access or lateral movement from affected systems
  • Monitor for any signs of persistent malware that may remain after package removal
