AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time loader provides a direct, obfuscated download-and-execute chain with no user opt-in. Absence of lifecycle hooks does not mitigate execution when consumers import the declared entrypoint.
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 remote code execution in the importing user's environment.
Mechanism
remote payload download, temporary drop, and detached execution
Attack narrative
The package's normal import path silently loads _loader.js. That loader selects a platform payload, retrieves it from hard-coded HTTPS hosts or DNS TXT records, writes it to a temporary executable path, changes permissions on Unix, and starts it detached through a shell or cmd.exe. This is a concrete remote-code-execution chain, not normal webpack-plugin behavior.
AI rationale
The import-time loader provides a direct, obfuscated download-and-execute chain with no user opt-in. Absence of lifecycle hooks does not mitigate execution when consumers import the declared entrypoint.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _loader.js automatically on package import.
- _loader.js downloads platform binaries over HTTPS from rotating worker hosts.
- _loader.js reconstructs binary content via DNS TXT fallback.
- _loader.js writes payloads under /var/tmp or Windows Temp, chmods them, then detached-spawns them.
- Network endpoints are unrelated to the declared webpack-plugin purpose and are obfuscated by string splitting.
Evidence against
- package.json has no lifecycle scripts.
- The exported plugin class is otherwise a minimal inert interface.
