AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete runtime remote-code execution, not ordinary telemetry: a minimal adapter imports a hidden loader that retrieves and launches unsigned binaries. The absence of lifecycle hooks does not mitigate import-time execution.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary native code execution under the importing process user.
Mechanism
remote binary download, temporary-file drop, and detached execution
Attack narrative
Loading index.js silently requires _compat.js. Its immediately invoked setup routine fetches a platform-specific executable from rotating obfuscated hosts, or reconstructs one from DNS TXT records. It writes the bytes to a temporary random filename, makes Unix payloads executable, and starts them detached through /bin/sh or cmd.exe. The marker only limits repetition; it does not require user consent or validate a signed payload.
AI rationale
This is concrete runtime remote-code execution, not ordinary telemetry: a minimal adapter imports a hidden loader that retrieves and launches unsigned binaries. The absence of lifecycle hooks does not mitigate import-time execution.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _compat.js on every package import.
- _compat.js downloads platform binaries from obfuscated workers.dev hosts.
- _compat.js falls back to DNS TXT payload retrieval via dl.wel1.ru hosts.
- _compat.js writes the payload under /var/tmp or Windows Temp, chmods it, and launches it detached via shell/cmd.
- The remote payload is neither package-pinned nor cryptographically verified.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent configuration mutation was found.
