A critical malware incident was identified in the npm package picasso.js. According to the GitHub Advisory (GHSA-6jmc-6w7f-v47v), 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 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, as the attacker may have gained full control of the system.\n\nThis represents a severe supply chain attack with potential for widespread impact across any development or production environment using this package.
