Which versions of sysau are malicious?

The following npm versions of sysau are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate sysau if I installed it?

Remove sysau from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is sysau part of a known attack campaign?

Yes — sysau is associated with the IN-MAL-2026-005653 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect sysau in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking sysau and packages like it before any post-install script runs.

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall sysau

What this malware does

On install/load, index.js auto-runs a bootstrap that silently installs Python 3.12 (via winget, falling back to a /quiet curl of python-3.12.3-amd64.exe to %TEMP%), pip-installs keyboard, pyautogui, mss, pillow, requests, and uiautomation, and spawns the bundled pointer.py. pointer.py installs a global keyboard hook, a clipboard-monitor loop, and an always-on-top transparent overlay; every clipboard change longer than 5 characters and full-screen JPEG captures (triggered by alt+s) are POSTed to the hardcoded endpoint https://iq-overlay-pointer.vercel.app/api (pointer.py line 32: VERCEL_API_URL = 'https://iq-overlay-pointer.vercel.app/api'). UIAutomation is used to scrape accessibility text from arbitrary windows, and the server's response is auto-typed back into the active window via pyautogui/keyboard — a remote-controlled input channel. The package's declared purpose ('System binary configuration tool', author 'SysDev') is a deliberate cover story: nothing about the advertised function justifies silently dropping a Python runtime, registering global hotkeys, capturing the screen, or transmitting clipboard contents to a third-party Vercel deployment. Any developer who installs sysau exposes their clipboard, screen, and keystrokes to the package author.
