Vulnerability from ossf_malicious_packages
forge-jsx is a malicious npm package that impersonates an Autodesk Forge SDK. It was published as a fully-formed RAT from its first version on April 7, 2026. Installing the package on any non-CI machine deploys a persistent background agent that captures all keystrokes, monitors clipboard content, recursively scans the filesystem for .env files, reads shell history, and opens a WebSocket-based remote filesystem backdoor. All stolen data flows to 204.10.194.247. Persistence survives reboots via systemd (Linux), LaunchAgent (macOS), and Task Scheduler (Windows).

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
