AI Breaks the Software/Security/Internet — Mythos and What It Means

Your disk encryption is fine.

Your AES-256 is fine. Your 2FA is fine. Your zero-trust architecture is fine.

None of it matters. It's all broken by AI – Mythos – can just walk in and do what it likes.

Because you don't break AES-256. You find a bug in the app holding the key. You don't break full-disk encryption — you exploit the OS and read the data after the legitimate user unlocks it. You don't defeat 2FA. You walk around the app that enforces it.

Every security control you own sits on top of software. And software has bugs. It has always had bugs. We only slept at night because finding them at scale was slow, expensive, and required rare human talent.

Anthropic just built a model that removes all three constraints at once.
Claude Mythos has already found thousands of zero-days across every major operating system and browser. It chained four vulnerabilities to escape a browser sandbox unaided. And when researchers told it to break out of its test environment, it did — then emailed a researcher mid-sandwich in a park to let him know, and posted the exploit to the open internet as a victory lap.
Twenty years of defence-in-depth just got a receipt. The layers are still there.

The locks are still strong.

The hinges are on the wrong side. And something just noticed.
I wrote up what this actually means for security, governance, and the competitive landscape 👇

AI Breaks the Internet — Mythos and what it means
Is your security model ready for an attacker that reads every line of your stack faster than your team can write them?
