AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain unrelated to the package's documented menu API. The package is malicious even though it has no npm lifecycle hook.
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, without an explicit setup command.
Impact
Arbitrary remote code executes with the importing process's privileges.
Mechanism
remote binary download/DNS payload retrieval followed by detached execution
Attack narrative
Loading index.js catches errors from but still invokes _adapter.js. The adapter obtains a platform-specific payload from rotating worker hosts or base64 DNS TXT records, writes it to a temporary path, makes it executable on Unix, and launches it detached through a shell or cmd.exe. A marker file delays subsequent execution; the downloaded bytes have no enforced integrity validation.
AI rationale
This is a concrete import-time remote payload execution chain unrelated to the package's documented menu API. The package is malicious even though it has no npm lifecycle hook.

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 at module load.
- _adapter.js fetches platform binaries from four worker hosts and DNS TXT resolvers.
- _adapter.js writes payloads to /var/tmp or TEMP, chmods them, then detached-spawns them.
- No checksum is actually verified despite the integrity-check comment.
Evidence against
- package.json has no lifecycle scripts.
- No credential or local-file harvesting was found in the entrypoint chain.
