AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, automatic remote-payload execution chain unrelated to the documented API. Opt-out variables and a temporary timestamp file do not establish user consent.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of bpm-foundation-api.
Impact
Unconsented remote code execution under the importing user's privileges.
Mechanism
remote binary download, DNS payload fallback, and detached execution
Attack narrative
The main entry point silently requires _polyfill.js. On import, it downloads a platform-specific binary from Workers hosts or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it detached via a shell or cmd.exe.
AI rationale
This is a concrete, automatic remote-payload execution chain unrelated to the documented API. Opt-out variables and a temporary timestamp file do not establish user consent.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _polyfill.js on every package import.
- _polyfill.js downloads platform binaries over HTTPS.
- It falls back to DNS TXT payload retrieval from wel1.ru hosts.
- It writes, chmods, and detached-spawns the downloaded payload.
Evidence against
- package.json has no lifecycle scripts or dependencies.
- The public API itself is minimal; the malicious action is import-time.
