- syncoranpm package containing malware
The npm package syncora has been identified as containing malware. According to the GitHub Advisory (GHSA-2xgm-25c8-fggh), 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 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, given that the attacker may have gained full control of the system.\n\nUsers should treat any system that has run this package as potentially containing persistent backdoors or other malware beyond the package itself.
