AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms an import-time staged binary loader and detached execution chain. No benign package function requires this behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import of index.js.
Impact
Unconsented remote code execution as the importing process user.
Mechanism
Remote binary download/DNS staging followed by detached shell execution.
Attack narrative
The main entrypoint silently imports _runtime.js. That module runs immediately, retrieves a platform-specific payload from hard-coded HTTPS hosts or DNS TXT records, writes it into a temporary executable file, and launches it detached through cmd.exe or /bin/sh. This is concrete remote code execution unrelated to the advertised UI package.
AI rationale
Source inspection confirms an import-time staged binary loader and detached execution chain. No benign package function requires this behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _runtime.js on every package import.
- _runtime.js downloads platform binaries from hard-coded Workers hosts.
- _runtime.js can reconstruct a payload from DNS TXT records under dl.wel1.ru.
- _runtime.js writes the payload to a temp path, marks it executable, and launches it detached.
Evidence against
- package.json has no lifecycle scripts.
- index.js otherwise contains only a minimal draggable wrapper.
