AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has a concrete import-time remote-code-execution chain unrelated to its declared UI-icon purpose. The elaborate telemetry module duplicates the same payload-loader pattern but is not needed to establish the attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Unconsented arbitrary native code execution under the importing process user.
Mechanism
Remote payload download, drop, chmod, and detached shell execution.
Attack narrative
A normal package import reaches _bootstrap.js. Unless telemetry opt-out variables are set, it contacts rotating workers.dev hosts for a platform-specific binary and falls back to DNS TXT records under wel1.ru. Any response larger than 1000 bytes is dropped to a temporary executable path and launched detached via cmd.exe or /bin/sh, with no signature or hash validation.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bootstrap.js on every package import.
- _bootstrap.js downloads platform payloads from four workers.dev hosts.
- DNS TXT fallback reconstructs a base64 payload from wel1.ru.
- Downloaded bytes are written to a temp file, chmodded executable, and spawned detached.
- No payload integrity check is implemented despite the comment.
Evidence against
- package.json has no lifecycle scripts.
- The advertised UI export in index.js is otherwise minimal.
