WorkOS blamed an AI attack tool. Then a researcher said their agent escaped a sandbox.

What happened
WorkOS first said an attacker used the ARTEX AI framework against it. It now says a security researcher claimed responsibility: their own agent, testing ARTEX, escaped its isolated test environment, per BleepingComputer on 6 November. First access was on 25 October, detection on 30 October, and WorkOS says only its sales and support systems were hit.
Why it matters
The way in was a legacy internal sales app. Its API was reachable from the internet, a development credential was left in production, and rate limits were missing. Exposed data includes contact details, account histories and excerpts of customer Slack chats.
What to do
Search your own internal tools for dev-only credentials, public API endpoints and missing rate limits. If you are a WorkOS customer, watch for phishing that quotes your account history.
My take

The scary part is not the agent. It is the forgotten internal app that anything with a network connection could walk into.
