The npm package test-dev-sync was found to contain malware. According to the GitHub Advisory (GHSA-c2gc-7pfc-7fjf), any system that has installed or executed this package should be treated as fully compromised.\n\nThe advisory recommends that all secrets and cryptographic keys stored on affected computers be rotated immediately 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 initial compromise, as the attacker may have gained full control of the system.\n\nUsers should assume complete system compromise and take appropriate incident response measures.
