A critical malware incident was identified in the npm package ts-toolkit-plus. According to the GitHub Advisory (GHSA-99wx-749q-58xh), any computer with this package installed or running should be considered fully compromised.\n\nThe advisory warns that all secrets and keys stored on affected computers should be rotated immediately from a different, uncompromised system.
