AI Disrupts Breach and Attack Simulation: The Post-Mythos Era

Breach and attack simulation (BAS) traditionally relied on human red teams to read threat reports, extract techniques, and convert them into simulation content that runs against security controls. Prior to recent months, converting a major new threat into working simulation content within 24 hours was considered very fast. Frontier AI models have disrupted this process in what is referred to as the post-Mythos era, breaking the previous symmetry of the BAS supply chain.
