AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package is a concealed remote data-collection and input-automation tool unrelated to its stated system-binary configuration purpose. Although no install hook runs it automatically, explicit CLI execution exposes clipboard and screen data without adequate consent.
Static reason
No blocking static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
User invokes sysb1 or npm start; clipboard monitoring begins immediately, while screenshot upload requires its registered hotkey.
Impact
Sensitive clipboard data and screenshots can be disclosed to a third party; remote responses can be typed into the active application.
Mechanism
Stealth clipboard/screen exfiltration with remote-response keyboard automation.
Attack narrative
When a user runs the advertised system utility, index.js launches pointer.py. The program hides its overlay, polls the clipboard every 300 ms, and sends changed text to iq-overlay-pointer.vercel.app without a per-item consent action. Its screen hotkey uploads a base64 image of the primary display. It also accepts remote answers into the clipboard and can automate or suppress keyboard input. A separate included VBS launcher requests elevation and hides execution.
AI rationale
The package is a concealed remote data-collection and input-automation tool unrelated to its stated system-binary configuration purpose. Although no install hook runs it automatically, explicit CLI execution exposes clipboard and screen data without adequate consent.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- pointer.py monitors clipboard every 300ms and posts changed text to a remote API.
- pointer.py captures the full screen, base64-encodes it, and uploads it to the same API.
- pointer.py implements hidden transparent UI, global hotkeys, and keyboard-input suppression/automation.
- start_tool.vbs requests elevation and silently launches pointer.py.
- index.js silently installs Python and privileged automation dependencies when the CLI is run.
Evidence against
- package.json contains no npm lifecycle hook; execution requires invoking the bin/start command.
- The Python installer URL is python.org and is only used when Python is absent.
