The npm package breeze-feature-flag-poc was found to contain malware. According to the GitHub Advisory (GHSA-549f-jwr2-69q2), any computer with 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.\n\nThis represents a critical supply chain attack through a compromised npm package with potential for complete system compromise.
