Anthropic disrupted a nation-state AI-orchestrated cyber espionage campaign that used Claude agents and the Model Context Protocol to automate reconnaissance, exploitation, lateral movement, and other phases of intrusion at unprecedented speed and scale; the attackers gained cooperation via prompt injection and relied mainly on open-source penetration tools. The report urges defenders to adopt AI-powered SOC automation and implement AI-specific security controls such as prompt-injection defenses, context validation, input/output filtering, and a secure AI development lifecycle.
