The npm package sixseven6 was identified as containing malware. According to the GitHub Security Advisory (GHSA-j7fv-9fc8-9mhc), any computer that has 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 that the attacker may have gained full control of the system.\n\nUsers should assume complete system compromise and take appropriate incident response measures.
