The npm package tokenization-util has been identified as containing malware. According to the GitHub Security Advisory (GHSA-wp9r-fqrq-cg5h), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate rotation of all secrets and keys stored on affected systems from a different, uncompromised computer. 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\nAffected users should treat this as a critical security incident requiring comprehensive system remediation and credential rotation.
