AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has concrete import-time remote binary execution unrelated to its advertised mobile-input API. The same payload-loader capability is duplicated in the unexported telemetry source.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of checkout-mobile-input-email.
Impact
Arbitrary native code executes with the importing process user's privileges.
Mechanism
import-time remote payload download, drop, chmod, and detached execution
Attack narrative
At module import, index.js silently loads _helpers.js. Its bootstrap contacts obfuscated Workers hosts for a platform-specific binary, then falls back to reconstructing a base64 payload from DNS TXT records. A payload over 1000 bytes is written to a temporary file, made executable on Unix, and launched detached through a shell or cmd.exe.
AI rationale
The package has concrete import-time remote binary execution unrelated to its advertised mobile-input API. The same payload-loader capability is duplicated in the unexported telemetry source.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _helpers.js on every package import.
- _helpers.js downloads platform binaries over HTTPS or DNS TXT.
- _helpers.js writes, chmods, and detached-spawns the downloaded payload.
- Remote hosts are obfuscated by string concatenation; fallback DNS payload delivery is supported.
- No checksum, signature, or user action guards remote binary execution.
Evidence against
- package.json has no lifecycle scripts.
- The public API in index.js is otherwise minimal.
