The 'nottuff2' package in the npm ecosystem is identified as containing malicious code that results in a full compromise of the host system. According to the source advisory, any system with this package installed or running should be considered fully compromised, necessitating immediate secret and key rotation from a separate, secure environment. The advisory warns that simply removing the package may not eradicate all malicious components introduced, indicating potential persistence mechanisms or additional payloads installed by the package.

Full system compromise on any computer with the 'nottuff2' package installed or running. This includes potential unauthorized access to all stored secrets and keys, which must be considered compromised and rotated. The presence of the package may lead to persistent malicious software beyond the package itself.

Remove the 'nottuff2' package immediately. Rotate all secrets and keys from a different, trusted computer. Because the system is considered fully compromised, further forensic analysis and remediation may be necessary to ensure complete removal of malicious software. No official patch or fix is available; remediation relies on removal and secret rotation.
