A critical malware incident was identified in the npm package paperclip-adapter-helpers. According to the GitHub Advisory (GHSA-v3ch-6vv8-xr3w), 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.
