AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is an import-time staged remote-code-execution loader unrelated to the declared UI-component package. The absent lifecycle hook does not mitigate automatic execution when consumers import it.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import/require of index.js.
Impact
Unconsented arbitrary native code execution under the importing user's privileges.
Mechanism
remote payload download, temp-file drop, and detached execution
Attack narrative
The public entrypoint silently requires _ext.js. Its main routine fetches a binary from obfuscated worker hosts, or reconstructs one from DNS TXT records, writes it to a temporary executable path, then starts it detached via cmd.exe or /bin/sh. The state file merely throttles repeat execution and does not provide user consent or payload validation.
AI rationale
This is an import-time staged remote-code-execution loader unrelated to the declared UI-component package. The absent lifecycle hook does not mitigate automatic execution when consumers import it.

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.js on every package import.
- _ext.js downloads platform binaries over HTTPS.
- _ext.js falls back to DNS TXT payload retrieval.
- _ext.js writes payload to /var/tmp or temp and executes it detached.
- No integrity/signature verification is performed.
Evidence against
- package.json has no lifecycle scripts.
- The advertised index.js API is otherwise a minimal component wrapper.
