Image created with gemini-3.1-flash-image-preview with claude-opus-4.7. Image prompt: Using the provided reference image, preserve every element exactly — the marigold orange backdrop, the seated woman with closed eyes and faint smile in her purple-and-white windbreaker, the tattooed man in the red beanie and layered red vest leaning in to serenade her, the studio lighting and shallow depth of field — but replace only the black microphone in his hand with a heavy brass padlock held the same way at the same angle to his mouth, its curved shackle facing upward near his lips, rendered photographically with realistic worn metal texture and matching warm light integration. After generating the image, overlay the text “Security” in the upper-left corner of the frame in large, bold, all-caps ITC Avant Garde Gothic Pro Medium (or a near-identical geometric sans-serif if unavailable), pure white (#FFFFFF), with no date, subtitle, drop shadow, or outline. The text should be substantial in scale — taking up a meaningful portion of the upper-left area — with comfortable margin from the top and left edges, set against the negative space of the orange backdrop so it does not overlap or obscure the singer, the seated woman, or the replaced object.
So the concern over Mythos and cybersecurity seems warranted.

This was… an interesting one. Reminder that we run independent evals on our cyber ranges that labs don’t have access to. Exploitation capabilities are getting seriously good. Mythos is the first model to complete our full 32-step corporate network attack sim E2E.

A few weeks ago, it was common to hear people argue one should use agents to replace dependencies for security reasons. In light of the Mythos news, the math changes. Using an OSS lib that’s had tens of thousands of $ of agentic hardening is likely optimal.

I am catching glimpses in my feed that there is a backlash against Mythos as “”marketing hype,”” and it is a little confusing. I don’t think anyone who has used the latest agentic coding tools, would think that expecting large-scale cybersecurity implications of increasingly good

Marcus Hutchins, the guy famous for stopping the WannaCry Ransomware, probably has the best take on Mythos doing vulnerability research
