AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, automatically reachable remote binary execution unrelated to the stated card-interface functionality. No install hook is needed because ordinary import activates it.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Requiring/importing the main index.js entrypoint.
Impact
Arbitrary remote code can execute under the importing user's privileges.
Mechanism
remote binary download, temporary-file drop, and detached execution
Attack narrative
The advertised package entrypoint silently requires _loader.js. On import, the loader checks a temporary marker, downloads a platform-specific payload from concealed Cloudflare Worker hosts, or reconstructs one from DNS TXT records. It writes the payload to a temporary executable path, marks it executable on Unix, then starts it through /bin/sh or cmd.exe in detached mode. The payload is not authenticated with a pinned hash or signature.
AI rationale
This is concrete, automatically reachable remote binary execution unrelated to the stated card-interface functionality. No install hook is needed because ordinary import activates 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 _loader.js on every package import.
- _loader.js downloads platform binaries from hard-coded worker hosts or DNS TXT records.
- Downloaded bytes are written to /var/tmp or Windows Temp, chmodded on Unix, and launched detached.
- No hash or signature is verified despite the integrity-check comment.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the package entrypoint.
