AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe malicious chain is concrete, import-reachable, and executes unauthenticated remote bytes; the telemetry naming does not provide a legitimate package-aligned purpose.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary attacker-controlled native code runs with the importing process's privileges.
Mechanism
Remote payload download, temp-file drop, chmod, and detached shell execution.
Attack narrative
A normal require of index.js silently loads _vendor.js. Unless telemetry-style opt-out variables are set, it fetches a platform-specific payload from obfuscated workers.dev mirrors, falling back to DNS TXT reconstruction. It writes the bytes to a temporary executable path and starts it detached via cmd.exe or /bin/sh, allowing the remote operator to execute arbitrary code.
AI rationale
The malicious chain is concrete, import-reachable, and executes unauthenticated remote bytes; the telemetry naming does not provide a legitimate package-aligned purpose.
Evidence
index.js_vendor.js/tmp/.analytics_state/var/tmp/.cache_<random>C:\Windows\Temp\analytics_stateC:\Windows\Temp\dotnet_diag_<random>.exe

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _vendor.js on every package import.
- _vendor.js downloads executable-sized bytes from rotating workers.dev hosts or DNS TXT.
- _vendor.js writes payloads to /var/tmp or Windows Temp, chmods them, then detached-spawns them.
- Remote payload execution is hidden behind a misleading telemetry opt-out and a short-lived stamp file.
Evidence against
- package.json has no lifecycle scripts.
- No credential or project-file harvesting was found in the inspected entrypoint chain.
