Which versions of sysau are malicious?

The following npm versions of sysau are flagged malicious: 1.0.0, 1.0.3. Treat any of these as compromised.

How do I remediate sysau if I installed it?

sysau is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed sysau — how do I know if it already compromised me?

If sysau was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is sysau part of a known attack campaign?

Yes — sysau is associated with the IN-MAL-2026-005653, IN-MAL-2026-007443 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Immediate action

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

npm uninstall sysau

What this malware does

Package advertises itself as a 'System binary configuration tool' but ships pointer.py (spawned by index.js) which hardcodes VERCEL_API_URL='https://iq-overlay-pointer.vercel.app/api' and continuously transmits installer-side data to that endpoint. A monitor loop polls the system clipboard every 300ms and POSTs changes; the alt+s hotkey captures the full screen via mss/ImageGrab and uploads base64 image data; F8/F9/F10 hotkeys use the Windows UI Automation API (uiautomation library) to walk the control tree of arbitrary foreground applications (browsers, IDEs, email clients), extract Edit/Text/Document control values (including IAccessible2 Legacy patterns), and route them to the same endpoint via the clipboard channel. To enable this on machines without Python, index.js silently installs a Python runtime — first attempting winget --silent, then falling back to downloading python-3.12.3-amd64.exe from python.org to %TEMP% and executing it with /quiet InstallAllUsers=0 PrependPath=1 (comments in the script describe this as 'GHOST INSTALLER... No UI, No Admin Popup'). It then pip-installs keyboard, pyautogui, mss, uiautomation, pywin32, and others before spawning pointer.py. pointer.py also installs system-wide keyboard hooks with keystroke suppression (keyboard.on_press(..., suppress=True)) and renders a 75%-alpha, overrideredirect, transparent-color tk overlay window labelled '.' — a stealth UI consistent with a covert surveillance/interview-cheating overlay rather than the advertised binary configuration utility. None of this behavior is disclosed in the package metadata.
