AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has no legitimate SDK functionality beyond a minimal class, while import-time code performs covert remote binary staging and execution. This is a concrete arbitrary-code-execution chain.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of index.js.
Impact
Arbitrary native code execution with the importing process user's permissions.
Mechanism
Remote payload download, temporary-file staging, and detached shell execution.
Attack narrative
Requiring the advertised SDK loads setup.js without user action. That module retrieves a platform-specific opaque payload from rotating HTTPS endpoints or DNS TXT records, stores it under a disguised temporary filename, applies execute permission on Unix, and launches it through a detached shell or cmd.exe process. The long telemetry module contains a parallel configurable implementation of this loader.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./setup on every package import.
- setup.js downloads platform-specific binaries from obfuscated workers.dev hosts.
- setup.js falls back to DNS TXT payload retrieval from wel1.ru hosts.
- setup.js writes the payload to /var/tmp or Windows temp, marks it executable, and spawns it detached.
- lib/telemetry.js independently implements the same download-to-temp-and-execute flow.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent configuration writes were found.
