The npm package @bcryptln/bcryptjs has been identified as containing malware. According to the GitHub Advisory (GHSA-qw92-vxcv-397r), 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 package installation, as the attacker may have gained full control of the system.\n\nThis is a critical supply chain attack affecting the npm ecosystem through a compromised package.
