As Anthropic’s Mythos model grabbed headlines for its uncanny ability to unearth software flaws at scale, a quiet gathering unfolded just outside Washington, D.C. Security practitioners from NIST, OWASP, SANS, and CoSAI crammed into a conference room. They debated how to shield AI systems from threats that now favor attackers. Models like Mythos don’t just demonstrate power. They expose fragility.
Rob van der Veer, chief AI officer at Software Improvement Group and founder of OWASP’s AI Exchange, led the talks. “They show that weaknesses in AI systems can now be found faster and at scale—often before developers are aware of them,” he said. “This shifts the balance toward attackers and reduces the margin for error.” (Fortune)
Mythos did more than talk. Mozilla tapped an early preview through Anthropic’s Project Glasswing. The result? 271 vulnerabilities patched in Firefox 150. Firefox CTO Bobby Holley called it a game for defenders. “Defenders finally have a chance to win, decisively,” he noted in a blog post. No bugs surfaced that elite humans couldn’t spot. But speed matters. Attackers get these tools soon. (Mozilla Blog; Ars Technica)
Gary McGraw, co-founder of Berryville Institute of Machine Learning, drew parallels to the 1990s software boom. “We didn’t have to panic when software swamped the world,” he said. “Security loves a good story with a flaming pile of broken stuff and the fire department coming to the rescue.” Fundamentals endure. Yet AI benchmarks measure task performance, not system security itself. (Fortune)
Apostol Vassilev from NIST hammered home the dynamic nature of AI threats. No finite guardrails block all adversarial prompts. “Ultimately, the goal is to reach an equilibrium that makes it difficult and costly for attackers to find new exploits,” he explained. “But that can only happen if businesses invest in adopting and maintaining this dynamic posture.” Continuous red teaming. Patching. Resilience. Static fixes won’t cut it. (Fortune)
CoSAI, the Coalition for Secure AI, pushes collective action. An open ecosystem under OASIS Open, it unites OpenAI, Anthropic, Google, and others to share practices against model theft, data poisoning, prompt injection. “Security requires collective action and the best way to secure AI is with AI,” their site states. Workstreams target secure building, integration, deployment. (CoSAI.org)
OWASP’s AI Exchange offers 300+ pages of guidance. Threat matrices. Controls by asset and impact. Labs like PwnzzAI simulate prompt injection, poisoning. Their Top 10 for Agentic Applications 2026 lists goal hijack, tool misuse, identity abuse. Agent ASI01: Attackers twist objectives via malicious text. Mitigate with human-in-the-loop, verifiable intent. (OWASP; OWASP AI Exchange PDF)
SANS Institute hosted its AI Cybersecurity Summit April 20-21 in Arlington, mere days before the D.C. huddle. Sold-out in-person, virtual drew crowds. Keynotes from Bruce Schneier on AI integrity, Jacob Klein on Anthropic intel, Anne Neuberger on cyber contests. Workshops: Hands-on OWASP threat modeling. Offensive AI exploitation. CoSAI prep talk by Jason Garman. NIST AI RMF featured in lightning rounds. (SANS.org; SANS Blog)
NIST’s AI Risk Management Framework stresses govern, map, measure, manage. Recent updates tackle agent identities. February 2026 initiative questions permission inheritance. Agents need distinct non-human IDs, least privilege, just-in-time access. Logs must separate agent from human actions. Over 90% of cloud identities overprivileged already. (NIST AI RMF)
Fragmentation plagues the field. Overlapping frameworks. Competing metrics—use cases? Infrastructure? Outcomes? Van der Veer pushes alignment. “Aligning standards and guidance across initiatives reduces fragmentation, improves clarity, and gives practitioners a coherent path forward,” he said. It enables fast adoption without chaos. (Fortune)
Mythos accelerates discovery both ways. Mozilla fixed 271 bugs. But attackers scan code autonomously now. Vlad Korsunsky warns firms ignoring protocols face elimination as AI grabs admin powers. Cloud Security Alliance dubs it the “AI Vulnerability Storm.” Adjust patching cadences. Reorient resources. (X post by OSN_Reports)
White House weighs in. A memo outlines defenses against distillation attacks, where foes copy models from queries. Cerebras eyes IPO amid AI chip rush. Political heat builds on lobbying. Yet optimism lingers. McGraw stays bullish on progress. Industry adapts, as in software’s past.
Standards bodies converge. D.C. meeting signals urgency. Mythos forces the issue. Attackers scale faster. Defenders must match. Equilibrium demands investment. Dynamic defenses. Aligned rules. Or risks mount unchecked.
Fragmented no more.
