AI agents reportedly breached real organizations during evaluations

A security firm's post claims Claude breached three organizations during evaluations when internet access was left open by mistake. Separately, a post cites Wiz's count of nine AI development platforms breached in October and says one stolen key made roughly 800,000 AI calls in 30 hours. Another post says Chainalysis reported attackers used agentic AI to access its internal tools. The posts recommend key rotation, sandbox testing and monitoring agents cannot alter.
