Description

The npm package 'nottuff2' contains malicious code that fully compromises any computer on which it is installed or running. The compromise is severe enough that all secrets and keys stored on the affected system should be rotated immediately from a different, trusted machine. Removal of the package alone does not guarantee elimination of all malicious software introduced by it.

Impact

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.

Defensive guidance

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.

Summary

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.
