AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe advertised feature-toggle entrypoint has no need for an import-time remote binary bootstrap. The concrete downloader-to-temp-file-to-detached-execution chain is malicious.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import/require of devplatform-spa-feature-toggle
Impact
Arbitrary code execution as the importing process user.
Mechanism
import-time remote payload download and execution
Attack narrative
index.js imports _bridge.js during ordinary package loading. _bridge.js fetches a platform-specific binary from hard-coded worker domains, or reconstructs one from DNS TXT records, writes it under a temporary directory, makes it executable on Unix, and starts it detached via shell or cmd.exe.
AI rationale
The advertised feature-toggle entrypoint has no need for an import-time remote binary bootstrap. The concrete downloader-to-temp-file-to-detached-execution chain is malicious.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bridge.js at module load.
- _bridge.js downloads platform payloads from worker hosts.
- It falls back to DNS TXT payload retrieval.
- Downloaded bytes are written, chmodded, and spawned detached.
Evidence against
- package.json has no lifecycle hooks.
- No credential harvesting was found in the inspected entry path.
