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).
