AI Security Review
scanned 3mo ago · by lpm-firewall-aiConcrete import-time download-and-execute behavior establishes malicious remote code execution. The lack of lifecycle hooks does not mitigate the reachable import-time trigger.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint.
Impact
Arbitrary attacker-controlled native code can run under the importing process's user account.
Mechanism
Remote payload download/DNS retrieval followed by temp-file execution.
Attack narrative
At import time, index.js silently requires _loader.js. It contacts obfuscated remote hosts for a platform-specific binary, with DNS TXT payload retrieval as fallback, writes the response to a temp file, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is an unverified remote-code-execution chain unrelated to the advertised UI package.
AI rationale
Concrete import-time download-and-execute behavior establishes malicious remote code execution. The lack of lifecycle hooks does not mitigate the reachable import-time trigger.

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 on every package import.
- _loader.js downloads platform binaries from obfuscated Workers hosts.
- _loader.js falls back to DNS TXT payload retrieval from *.dl.wel1.ru.
- Downloaded bytes are written to temp storage, chmodded, then detached-spawned via shell.
- No checksum, signature, or user opt-in protects the remote executable.
Evidence against
- package.json has no npm lifecycle scripts.
- The public UI API in index.js is small and does not require this loader.
