To Stop AI-Powered Adversaries, Defenders Must Fight Fire With Fire
CrowdStrike, Monday, November 17th, 2025
Anthropic's Threat Intelligence team recently uncovered and disrupted a sophisticated nation-state operation that weaponized Claude's agentic capabilities and the Model Context Protocol (MCP) to orchestrate automated cyberattacks simultaneously against multiple targets worldwide.
This AI-powered attack automated reconnaissance, vulnerability exploitation, lateral movement, and more across multiple victim environments at unprecedented scale and speed. We commend Anthropic for their swift response, their transparency in sharing detailed findings with the community, and for issuing a critical call to action to defenders worldwide:
"The cybersecurity community needs to assume a fundamental change has occurred: Security teams should experiment with applying AI for defense in areas like SOC automation, threat detection, vulnerability assessment, and incident response and build experience with what works in their specific environments."1 The message is clear: To defeat AI-powered adversaries, we must fight fire with fire.
