The Zero-Day Singularity: Inside Claude Mythos and the Era of Autonomous RCE
Let’s be honest. For a while, the “AI in cybersecurity” hype was exhausting. We watched vendors slap an “AI-powered” sticker on standard regex-based static analysis tools, and we watched script kiddies use early LLMs to write incredibly noisy, broken phishing emails.
But as of mid-2026, the joke is officially over.
The landscape of offensive security hasn’t just shifted; it has fundamentally fractured. We are no longer talking about AI as an “assistant” that helps a human pentester write a tricky payload. We are dealing with fully autonomous, parallelized agents that can reason through complex business logic, chain vulnerabilities, and pop shells before a human analyst has even finished their first cup of coffee.
