Executive Summary
In April 2026, the cybersecurity landscape witnessed a significant shift with the emergence of frontier AI models like Anthropic's Claude Mythos. These advanced AI systems demonstrated unprecedented capabilities in autonomously identifying and exploiting software vulnerabilities, effectively performing tasks that previously required extensive human expertise. The rapid development and deployment of such models have raised concerns about their potential misuse, as they can lower the barrier for launching sophisticated cyberattacks and accelerate the exploitation of vulnerabilities across critical infrastructures.
