  • @tenforce/toolbox-fontmap

A critical malware incident was identified in the npm package @tenforce/toolbox-fontmap. According to the GitHub Security Advisory (GHSA-4pgr-qgvj-c2wh), any computer that has this package installed or running should be considered fully compromised.\n\nThe advisory indicates that all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised system. While the package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning there is no guarantee that removing the package alone will eliminate all malicious software resulting from the installation.\n\nThis represents a supply chain attack through a compromised npm package with severe impact on system integrity and security posture.
