A critical malware incident was identified in the npm package @flex-ng/error-component. According to the GitHub Advisory (GHSA-pw64-8rr7-9h66), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory indicates that all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised system. While the package should be removed, there is no guarantee that removal will eliminate all malicious software that may have been installed as a result of the package installation, as the attacker may have gained full control of the system.\n\nThis represents a severe supply chain attack through a compromised npm package with potential for widespread impact across all systems that have installed or executed it.

Indicators of compromise

Packages

Remediation

  • Immediately isolate any system with @flex-ng/error-component installed from the network
  • Rotate all secrets, API keys, credentials, and signing keys from a clean, uncompromised system
  • Remove the @flex-ng/error-component package from all systems
  • Conduct a full forensic analysis of affected systems to identify any additional malicious software or persistence mechanisms
  • Review system logs and network traffic for indicators of compromise or data exfiltration
  • Consider full system reimaging if the system handles sensitive data or credentials
  • Audit all systems that may have been accessed or compromised through affected machines
