AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload download-and-execute chain unrelated to the stated declaration-generator functionality. 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 runtime require/import of index.js.
Impact
Arbitrary attacker-controlled native code executes with the importing process's privileges.
Mechanism
Remote binary download, temp-file drop, and detached execution.
Attack narrative
The public entrypoint silently imports _init.js. That module contacts obfuscated remote Workers hosts for a platform-specific binary, falls back to DNS TXT records, writes a sufficiently large response to a temporary executable, marks it executable on Unix, and launches it via a detached shell or cmd.exe. A timestamp marker suppresses repeat execution.
AI rationale
This is a concrete import-time remote payload download-and-execute chain unrelated to the stated declaration-generator functionality. 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 ./_init on every package import.
- _init.js downloads platform binaries from obfuscated Workers hosts.
- _init.js has DNS TXT fallback payload retrieval.
- _init.js writes a temp binary, chmods it, then detached-spawns it.
- Payload execution is rate-limited via a /tmp marker, not user-invoked.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or exfiltration was found in the active entrypoint.
