AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote code execution concealed behind an unrelated wrapper API. The absence of lifecycle scripts 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 runtime require/import of index.js.
Impact
Arbitrary attacker-controlled native code executes as the importing user.
Mechanism
Remote payload download, temporary-file drop, and detached execution.
Attack narrative
The package’s ordinary import path loads _shim.js, whose top-level call starts an asynchronous downloader. It tries obfuscated workers.dev endpoints and then DNS TXT records for platform-specific payload bytes, stores a sufficiently large result under /var/tmp or the Windows temp directory, marks Unix payloads executable, and starts them detached through /bin/sh or cmd.exe.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _shim.js on every package import.
- _shim.js immediately invokes run() at module load.
- _shim.js downloads platform binaries from three workers.dev hosts or DNS TXT fallbacks.
- _shim.js writes the downloaded payload to a temp path, chmods it on Unix, then launches it detached via shell/cmd.
- The public API is a minimal inert wrapper unrelated to this downloader.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent configuration mutation was found.
