AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, automatic remote-code-execution chain in the package import path. The lack of an npm lifecycle hook does not mitigate the unconsented runtime payload execution.
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 remote code executes with the importing process's privileges.
Mechanism
import-time remote payload download, drop, chmod, and detached execution
Attack narrative
Requiring the declared main entrypoint loads _init.js, which immediately invokes setup(). Unless opt-out environment variables or a short-lived marker prevent it, setup downloads a payload from rotating HTTPS endpoints, falling back to DNS TXT chunks. It writes the payload into a temporary directory, makes non-Windows files executable, and launches it detached via cmd.exe or /bin/sh.
AI rationale
This is a concrete, automatic remote-code-execution chain in the package import path. The lack of an npm lifecycle hook does not mitigate the unconsented runtime payload 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 _init.js on every package import.
- _init.js downloads platform payloads from rotating workers.dev hosts or DNS TXT.
- _init.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it.
- The download/execute chain is automatic and has no user invocation requirement.
Evidence against
- package.json has no lifecycle scripts.
- Public Retriever API is otherwise minimal; lib/telemetry.js is not imported by the entrypoint.
