A malware incident has been identified in the npm package @peptideventure/peptide-score-modifier. According to the GitHub Advisory (GHSA-jw4c-f75m-9wfj), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate action: all secrets and keys stored on affected computers should be rotated 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 compromise, as the attacker may have gained full control of the system.\n\nThis represents a critical supply chain attack through a compromised npm package with potential for widespread impact across all systems that have installed or executed this package.
