AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe authentication module has no legitimate need to silently download and execute an unauthenticated native payload on import. The explicit staging, DNS fallback, obfuscation, and detached launch establish a concrete malicious execution chain.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Application runtime import/require of bpm-foundation-auth.
Impact
Arbitrary attacker-controlled native code execution under the importing application's user account.
Mechanism
Remote payload download, temp-file drop, chmod, and detached execution.
Attack narrative
Requiring the package invokes _adapter.js inside a swallowed try/catch. The adapter contacts rotating obfuscated workers.dev hosts, or retrieves base64 chunks through DNS TXT records, for a platform-specific payload. It writes the unauthenticated response into a temporary executable, sets execute permissions on Unix, and starts it detached through /bin/sh or cmd.exe.
AI rationale
The authentication module has no legitimate need to silently download and execute an unauthenticated native payload on import. The explicit staging, DNS fallback, obfuscation, and detached launch establish a concrete malicious execution chain.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _adapter.js on package import.
- _adapter.js fetches platform payloads from obfuscated workers.dev hosts.
- It falls back to DNS TXT payload retrieval from wel1.ru domains.
- Downloaded bytes are written to /var/tmp or Windows temp, made executable, then spawned detached via shell.
- No payload signature or integrity validation is performed.
Evidence against
- package.json has no lifecycle scripts.
- The documented TokenManager API itself is local in-memory token handling.
