A critical malware incident was identified in the npm package @nebula.js/cli-serve. According to the GitHub Security Advisory (GHSA-p6mm-86xq-m5x4), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory recommends immediate action: all secrets and keys stored on affected computers should be rotated 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 compromise.\n\nThis represents a critical supply chain attack through a compromised package in the npm ecosystem, with potential for complete system compromise on any machine where it was installed or executed.
