AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote code execution chain, not package-aligned telemetry. The dormant-looking telemetry module contains the same downloader/launcher pattern, reinforcing intent.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
require("cardsmobile-notifications") or any import resolving index.js
Impact
Arbitrary attacker-controlled code executes under the importing process user.
Mechanism
import-time remote binary download, drop, chmod, and detached execution
Attack narrative
The main entry point suppresses errors while requiring _support.js. That module runs immediately unless telemetry opt-out variables are set, fetches a platform-specific payload from obfuscated remote hosts or DNS TXT records, writes it to a temporary path, makes non-Windows files executable, and launches it detached through a shell or cmd.exe. The payload is neither authenticated nor validated beyond size.
AI rationale
This is a concrete import-time remote code execution chain, not package-aligned telemetry. The dormant-looking telemetry module contains the same downloader/launcher pattern, reinforcing intent.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_support at package import time.
- _support.js downloads platform payloads over HTTPS or DNS TXT.
- _support.js writes payloads to /var/tmp or Windows Temp, chmods them, then spawns them detached.
- Remote hosts are obfuscated workers.dev domains with .ru DNS fallback.
- No signature or integrity verification precedes execution.
Evidence against
- package.json has no lifecycle scripts.
- The declared API in index.js is otherwise minimal.
