AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe public entrypoint activates a concealed downloader/executor at import time. Its network fallback, hidden temp payload, and detached execution are not package-aligned scroll functionality.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime require/import of index.js
Impact
Remote operator-controlled code executes with the importing process's privileges.
Mechanism
remote payload download, temporary-file drop, and detached shell execution
Attack narrative
On every import, index.js silently requires _ext.js. That module retrieves a large operator-controlled payload from hard-coded HTTPS hosts, or decodes it from DNS TXT records if HTTPS fails. It writes the bytes into a temporary executable file, makes it executable on Unix, and launches it detached via /bin/sh or cmd.exe. This is a concrete remote-code-execution chain without user action or payload verification.
AI rationale
The public entrypoint activates a concealed downloader/executor at import time. Its network fallback, hidden temp payload, and detached execution are not package-aligned scroll functionality.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_ext during package require.
- _ext.js downloads platform payloads from hard-coded Workers hosts.
- _ext.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- _ext.js writes payload to /var/tmp or Windows temp, chmods it, then detached-spawns it.
- No payload hash or signature is verified despite integrity comments.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
