AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package's stated API does not require a native executable, yet import-time code silently downloads and executes one with no meaningful integrity verification. The remote payload source and execution are attacker-controlled.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any Node.js require/import of the package main entrypoint.
Impact
Arbitrary attacker-supplied native code executes with the privileges of the importing process.
Mechanism
remote payload download, drop, chmod, and detached execution
Attack narrative
The main entrypoint catches and suppresses errors while importing _runtime.js. That module immediately retrieves an opaque platform payload from rotating Workers hosts, falling back to attacker-controlled DNS TXT chunks. It writes the result to a temporary executable path, grants execute permission on Unix, and launches it detached through /bin/sh or cmd.exe. This is a concrete import-time remote-code-execution chain, not legitimate telemetry.

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 downloads platform-specific binary payloads from worker hosts or DNS TXT records.
- Downloaded bytes are written under /var/tmp or Temp, chmodded executable on Unix, then detached-spawned.
- Payload retrieval uses oob-worker.cf102-baf.workers.dev and .ru DNS fallback domains.
- A temporary marker suppresses repeat execution, indicating stealthy runtime staging.
Evidence against
- package.json contains no lifecycle scripts.
- The public index API is otherwise a minimal inert class.
