The npm package path-internal-util was identified as containing malware. According to the GitHub Security Advisory (GHSA-c267-q765-387r), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends that all secrets and keys stored on affected computers be rotated immediately 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 initial compromise, given the potential for full system access by the attacker.\n\nUsers should treat any system that has had this package installed as potentially fully compromised and take appropriate incident response measures.
