The role of AI in cybersecurity has shifted from a defensive aid to the primary architect of offensive operations. Anthropic's 'Mythos' model and OpenAI's 'GPT-5.5' have demonstrated the ability to autonomously discover and weaponize vulnerabilities that were previously invisible to human researchers. This 'Synthetic Exploitation' is the driving force behind the collapse of the patch window. We are seeing a transition from 'AI-assisted' hacking to 'AI-led' campaigns, where human actors merely set the strategic objectives and the AI handles the technical execution. The security impact is CRITICAL, as current defensive AI systems are struggling to keep pace with the sheer volume of synthetic threats.
