AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an import-time downloader/dropper/executor with concealed endpoints and no payload validation. The absence of an npm lifecycle hook does not mitigate execution on normal package import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of index.js
Impact
Arbitrary native code execution under the importing user's permissions.
Mechanism
Remote payload download, drop, chmod, and detached execution
Attack narrative
The package’s declared main file catches errors while importing _loader.js, so normal runtime import silently activates it. The loader retrieves a large platform-specific binary over HTTPS or reconstructs one from DNS TXT records, drops it under a benign-looking temporary filename, makes it executable on Unix, and launches it detached. This is an unconsented remote-code execution chain, not functionality needed by the exposed UI API.
AI rationale
Direct source inspection confirms an import-time downloader/dropper/executor with concealed endpoints and no payload validation. The absence of an npm lifecycle hook does not mitigate execution on normal package import.

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 four worker hosts.
- _loader.js falls back to DNS TXT payload retrieval from dl.wel1.ru hosts.
- _loader.js writes a hidden/random executable in temp storage and chmods it.
- _loader.js launches the downloaded file detached via cmd.exe or /bin/sh.
- Network, execution, and failures are deliberately silent.
Evidence against
- package.json has no lifecycle scripts.
- index.js exposes a small UI-looking API, but its import side effect is unrelated.
