SANS Institute, in collaboration with the Cloud Security Alliance, [un]prompted, and the OWASP GenAI Security Project, has released an emergency strategy briefing titled “The AI Vulnerability Storm: Building a Mythos-Ready Security Program.” The report delivers a comprehensive framework for CISOs to respond to the rapidly shrinking gap between vulnerability discovery and exploitation driven by AI.
Developed in a single weekend by over 60 contributors and reviewed by more than 250 CISOs globally, the briefing reflects an urgent industry response to emerging AI capabilities. It highlights how next-generation systems such as Claude Mythos are dramatically accelerating vulnerability discovery identifying thousands of zero-day flaws and generating working exploits at unprecedented speed.
The report outlines a 13-item risk register aligned with leading frameworks, including OWASP, MITRE ATLAS, and NIST CSF 2.0, alongside 11 priority actions and a board-ready executive briefing. A key message is clear: traditional patch cycles are no longer sufficient in an era where AI can reverse-engineer fixes and weaponize vulnerabilities within hours.

Over the past 12 months, the cybersecurity landscape has seen a sharp escalation in AI-driven offensive capabilities. From autonomous systems outperforming human hackers to AI executing full attack chains, the pace of threat evolution has intensified significantly. The briefing notes that the average time from vulnerability disclosure to exploitation has dropped to less than a day in 2026, compared to years just a few years ago.
“Attackers already operate as syndicates… Defenders have to do the same,” said Gadi Evron. He emphasized the need for organizations to adopt AI-driven defense strategies, build collaborative security models, and establish dedicated Vulnerability Operations (VulnOps) functions.
The report also warns of increasing regulatory pressure, with frameworks such as the EU AI Act set to introduce stricter compliance requirements around AI security and governance.
With actionable guidance and immediate steps, the briefing serves as a critical playbook for organizations aiming to stay ahead in an AI-driven threat landscape where speed, automation, and collaboration will define cybersecurity resilience.
