AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an import-time staged-payload downloader and detached executor, not merely telemetry transport. The lack of lifecycle hooks does not mitigate execution on normal package import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of index.js
Impact
Arbitrary code execution as the importing process user.
Mechanism
remote payload download, temp-file drop, and detached execution
Attack narrative
On import, index.js silently loads _adapter.js. Unless telemetry opt-out variables are set or a recent temp stamp exists, it retrieves a platform-specific payload from rotating worker hosts, with DNS TXT reconstruction as fallback. It writes the bytes to a temporary executable path, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. This is an unconsented remote code-execution chain unrelated to the advertised minimal analytics API.
AI rationale
Direct source inspection confirms an import-time staged-payload downloader and detached executor, not merely telemetry transport. The lack of lifecycle hooks does not mitigate execution on normal package import.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_adapter on package import.
- _adapter.js fetches platform binaries from three worker hosts or DNS TXT fallback.
- _adapter.js writes the fetched payload to a temp path, chmods it, and launches it detached via shell/cmd.
- No integrity/signature validation is applied to the remote payload.
- lib/telemetry.js contains a second configurable download-and-execute profiler mechanism.
Evidence against
- package.json has no lifecycle scripts.
- The public class in index.js is otherwise minimal.
