Episode 09 | Mythos, GPT-5.4 Cyber, and Opus 4.7

In this episode of All About Identity, Ian Ahl breaks down the latest wave of AI-for-cyber news, from the hype and skepticism around Anthropic’s Mythos to OpenAI’s GPT-5.4 Cyber access program and the reality of what users are actually getting today. Along the way, he looks at what these model releases could mean for exploit discovery, defenders, and attackers alike, while keeping the conversation grounded in the fact that credential theft, phishing, and supply chain attacks still drive a huge amount of real-world compromise.

Ian also shares hands-on impressions from OpenAI’s Codex Security workflow, reacts live to the Opus 4.7 release, and puts the model through a network forensics challenge to see how well it handles triage, attack reconstruction, and detection ideas. The episode closes with a broader discussion on where these models are actually useful today, and whether it’s time to build better cyber benchmarks to measure what they can really do.
