AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time loader provides a concrete, unconsented remote payload execution chain. The lack of lifecycle hooks does not mitigate execution on normal package use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Importing or requiring the package entrypoint index.js.
Impact
Arbitrary attacker-controlled native code can execute with the importing process's privileges.
Mechanism
remote payload download, temp-file drop, and detached execution
Attack narrative
On package import, index.js silently requires _loader.js. The loader contacts rotating worker hosts for a platform-specific binary and falls back to DNS TXT chunks, writes the received bytes into a temporary executable, then launches it detached through cmd.exe or /bin/sh. This is an unverified remote-code-execution chain unrelated to the advertised UI component.
AI rationale
The import-time loader provides a concrete, unconsented remote payload execution chain. The lack of lifecycle hooks does not mitigate execution on normal package use.

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 during normal package import.
- _loader.js downloads platform binaries from worker hosts or DNS TXT records.
- _loader.js writes the downloaded content to a temp path, marks it executable, and detached-spawns it.
- No checksum, signature, or user opt-in protects the remote executable payload.
Evidence against
- package.json has no lifecycle scripts.
- The exported UI class itself is minimal; the malicious behavior is isolated to the import-time loader.
