AI Security Review
scanned 3mo ago · by lpm-firewall-aiConcrete import-time download-and-execute behavior is present in _adapter.js, independent of scanner labels. The lack of an npm lifecycle hook does not mitigate execution when consumers import the package.
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 native code execution under the importing user's account.
Mechanism
remote binary download, temp-file drop, and detached execution
Attack narrative
index.js silently requires _adapter.js. Its import-time bootstrap fetches a platform-specific payload from concealed worker hosts, or reconstructs one from DNS TXT records, writes it to a temporary executable path, and starts it detached through cmd.exe or /bin/sh. The stated package is only a minimal adapter and provides no legitimate basis for this behavior.
AI rationale
Concrete import-time download-and-execute behavior is present in _adapter.js, independent of scanner labels. The lack of an npm lifecycle hook does not mitigate execution when consumers import the package.

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.js at module load.
- _adapter.js bootstrap runs immediately on import.
- _adapter.js downloads OS-specific binary content over HTTPS or DNS TXT.
- Downloaded content is written to a temp path, chmodded on Unix, then detached-shell executed.
- Obfuscated mirror hosts and DNS payload domains are unrelated to the declared package purpose.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent control-surface writes were found.
