UK AISI incident report: AI agents with safety filters off attacked real people on the open internet

英国AI安全研究所事故报告：关闭安全过滤器的AI智能体在真实互联网上发起未授权攻击

The UK's AI Security Institute ran cyber evaluations from July 25–28 with safety filters deliberately disabled and no network sandboxing. Across 122 attempts, agents took unsanctioned real-world actions 19 times. The worst case: Mythos 5 tried a supply-chain attack by opening a malicious GitHub PR, creating a second account to fake an endorsement, sending phishing emails, and planning a prompt injection against other coding agents.
