Came across an incident where an autonomous AI agent deleted a startup’s production database (and possibly backups) in ~9 seconds.
The issue seems less about the AI itself and more about excessive permissions and a lack of guardrails or approval steps.
This raises questions about how AI agents should be scoped in terms of identity and access.

I do plan to expand it toward an EDR-style solution with a centralized detection server for admins.
