AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, automatic remote payload execution concealed behind an unrelated helper-utilities package. The absence of lifecycle hooks does not mitigate import-time execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import/require of cardsmobile-data-utils.
Impact
Arbitrary attacker-supplied native code executes with the importing process user's privileges.
Mechanism
automatic remote binary download, drop, and detached execution
Attack narrative
Loading index.js requires _vendor.js, which immediately invokes start(). It fetches a platform-specific binary from rotating HTTPS hosts, falling back to DNS TXT reconstruction, writes it under a randomized temporary filename, marks it executable on Unix, and launches it detached via a shell or cmd.exe.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _vendor.js on every package import.
- _vendor.js starts automatically at module load.
- _vendor.js downloads platform-specific binaries over HTTPS or DNS TXT.
- Downloaded data is written to a temporary executable file and chmodded on Unix.
- _vendor.js launches the payload detached through /bin/sh or cmd.exe.
- Obfuscated worker and .ru endpoints are unrelated to the documented helper utilities.
Evidence against
- package.json contains no npm lifecycle scripts.
- The exported index.js helpers are simple local utility functions.
