AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time staged-payload execution, not package-aligned telemetry. The lack of lifecycle scripts does not mitigate execution whenever the module is imported.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any require/import of index.js.
Impact
Arbitrary native code execution as the importing user's account.
Mechanism
remote binary download, drop, chmod, and detached execution
Attack narrative
Loading index.js silently requires _runtime.js. Its start() routine retrieves a platform-specific opaque payload from rotating external hosts or DNS TXT records, drops it under a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The payload is not integrity-checked.
AI rationale
This is concrete import-time staged-payload execution, not package-aligned telemetry. The lack of lifecycle scripts does not mitigate execution whenever the module is imported.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _runtime.js on every package import.
- _runtime.js fetches opaque payloads from rotating Workers hosts and DNS TXT records.
- Downloaded bytes are written to /var/tmp or Windows Temp, chmodded on Unix, then spawned detached.
- No integrity/hash verification is performed before execution.
Evidence against
- package.json has no npm lifecycle scripts.
- The exported adapter class itself is minimal; the attack is in its import-time side effect.
