AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, automatically triggered remote payload execution unrelated to the advertised test utilities. Absence of install 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
Runtime import/require of bnpl-forms-test-utils
Impact
Arbitrary code execution as the importing user
Mechanism
Remote payload download, temporary-file drop, chmod, and detached shell execution
Attack narrative
Requiring the package causes index.js to load _platform.js. That module retrieves a binary from obfuscated worker hosts, or reconstructs one from DNS TXT records, saves it under a disguised temporary filename, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe.
AI rationale
This is concrete, automatically triggered remote payload execution unrelated to the advertised test utilities. Absence of install hooks does not mitigate import-time execution.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_platform on every package import.
- _platform.js downloads platform binaries over HTTPS or DNS TXT.
- _platform.js writes the payload to /var/tmp or Windows Temp, chmods it, then spawns it detached.
- Remote hosts are obfuscated and include oob-worker.cf101-adf.workers.dev and *.wel1.ru.
- lib/telemetry.js contains a second configurable download-and-execute profiler implementation.
Evidence against
- package.json has no lifecycle scripts.
- The exported utility functions in index.js are otherwise benign.
