A critical malware incident was identified in the npm package cache-manager. According to the GitHub Security Advisory (GHSA-p7m5-96hg-gppj), any computer with this package installed or running should be considered fully compromised.
The advisory recommends immediate action: all secrets and keys stored on affected computers should be rotated from a different, uncompromised system. While the malicious 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 compromise, given that the attacker may have gained full control of the system.
Affected users should treat this as a critical security incident requiring comprehensive system remediation and credential rotation.
