AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote-code-execution chain unrelated to the advertised UI input package. The duplicated telemetry implementation contains the same downloader pattern but is not needed to establish the active attack surface.
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 remote native code executes under the importing user's privileges.
Mechanism
import-time remote payload download, drop, chmod, and detached execution
Attack narrative
The package main entrypoint catches and suppresses a require of _shim.js. That shim immediately fetches a platform-specific binary from hard-coded worker hosts, or reconstructs one from DNS TXT records. It writes the bytes to a temporary executable path, marks non-Windows files executable, and launches them detached through cmd.exe or /bin/sh. The payload source is unauthenticated and remote-controlled.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _shim.js on every package import.
- _shim.js downloads platform binaries from three worker hosts.
- _shim.js falls back to DNS TXT payload retrieval under wel1.ru.
- Downloaded bytes are written, chmodded, and detached-spawned.
- No integrity verification is implemented despite its comment.
Evidence against
- package.json has no lifecycle scripts.
- The public UI class itself is minimal; malicious behavior is in its import-time shim.
