AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe hidden import-time downloader and detached execution are unrelated to the documented helper API and provide direct unconsented code execution. The absence of lifecycle hooks does not mitigate runtime execution on import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of cardsmobile-command-utils
Impact
Arbitrary native code execution under the importing user's privileges.
Mechanism
remote binary download/DNS payload staging followed by detached execution
Attack narrative
The main entrypoint exports ordinary helpers, then silently requires _bridge.js. That module immediately runs main(), downloads a platform-specific opaque binary from obfuscated remote hosts or DNS TXT records, writes it under /var/tmp or Windows Temp, makes it executable on Unix, and starts it detached through a shell or cmd.exe. This is a concrete import-time remote-code-execution chain.
AI rationale
The hidden import-time downloader and detached execution are unrelated to the documented helper API and provide direct unconsented code execution. The absence of lifecycle hooks does not mitigate runtime execution on import.

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 during every package import.
- _bridge.js downloads binaries from obfuscated workers.dev hosts.
- _bridge.js falls back to DNS TXT payloads from wel1.ru domains.
- _bridge.js writes a temp executable, chmods it, and launches it detached.
- lib/telemetry.js contains the same download-to-execute primitive.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent configuration writes found.
