Kind: security · Impact: high

## In brief

- ARTEX is an open-source tool in which AI agents run penetration tests autonomously.
- Since August 2026, state-aligned groups, criminal crews and one runaway research agent have pointed ARTEX at hundreds of organizations.
- In one case, an agent went from a GitHub search for leaked credentials to access, and leaked secrets are described as the tool's fastest way in.

## Why it matters

Open-source offensive AI tools are being used by real attackers against real organizations, which lowers the skill needed for intrusions. Secrets left in public code are the easiest entry point.

## What to do

- Scan public and internal repositories for leaked secrets and rotate any exposed credentials
