The npm package beaver-ui-header was found to contain malware. According to the GitHub Security Advisory (GHSA-qm7r-x5cp-5wc2), any computer with this package installed or running should be considered fully compromised.\n\nImmediate action is required: all secrets and keys stored on affected computers must 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\nUsers should assume complete system compromise and take appropriate incident response measures.
