AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time downloader and detached execution are concrete malicious behavior, not telemetry. The unused telemetry implementation contains the same native-payload pattern and reinforces intent.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of index.js
Impact
Arbitrary native code execution under the importing user's privileges.
Mechanism
remote payload download, temporary-file drop, and detached execution
Attack narrative
index.js suppresses errors while requiring _polyfill.js, so ordinary package import starts its async loader. The loader tries obfuscated HTTPS hosts for a platform-specific executable and falls back to base64 payload chunks fetched through DNS TXT records. It writes the payload to a randomized temporary filename, makes it executable on Unix, and starts it detached through /bin/sh or cmd.exe. This is an unconsented staged remote-code-execution chain.
AI rationale
The import-time downloader and detached execution are concrete malicious behavior, not telemetry. The unused telemetry implementation contains the same native-payload pattern and reinforces intent.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _polyfill on every package import.
- _polyfill.js downloads platform binaries over HTTPS.
- _polyfill.js reconstructs binary data from DNS TXT records.
- _polyfill.js writes executable data to /var/tmp or Windows Temp.
- _polyfill.js chmods and detached-spawns the downloaded binary via shell.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent configuration writes found.
