AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package's normal import path contains a concealed, unauthenticated remote payload execution chain unrelated to its stated data-mapper/persistence-adapter purpose. This is concrete malware behavior.
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
Unconsented remote code execution as the importing user's OS account.
Mechanism
remote binary download, drop, chmod, and detached execution
Attack narrative
When the package is imported, index.js silently loads _init.js. That module selects a platform-specific endpoint, retrieves a binary from rotating Worker hosts or DNS TXT records, drops it to a temporary directory, marks it executable on Unix, and starts it detached through /bin/sh or cmd.exe. It does not authenticate the downloaded payload.

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 binaries from worker hosts or DNS TXT records.
- _init.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it via shell/cmd.
- Remote payload has no signature or integrity verification.
- Marker file only rate-limits repeated execution.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or data exfiltration was found in the inspected entrypoint.
