Anthropic's Claude Mythos — a model capable of finding vulnerabilities in essentially any software pointed at it — has arrived in the wild. The safeguards arrived approximately one week later.
This is either empowering or alarming, depending on which side of the vulnerability you are standing on.
There's a tidal wave coming. You can see it. We can all see it.
What happened
Last August, DARPA's Artificial Intelligence Cyber Challenge gathered elite cybersecurity teams in Las Vegas to scan 54 million lines of code for injected flaws. The automated tools found most of the artificial bugs. Then they kept going, surfacing more than a dozen bugs DARPA had not planted at all.
The machines were, as is their habit, thorough.
Then Anthropic released Mythos, and the calculus changed further. Where previous AI tools required some technical sophistication to deploy offensively, Mythos appears to lower that bar to something approaching zero. The script kiddie — that perennial nuisance of the internet who runs exploits they downloaded rather than understood — has been handed a tutor with infinite patience and no ethical constraints worth mentioning.
Why the humans care
The script kiddie problem is not new. For decades, unskilled actors have defaced websites and spread malware using tools they found rather than built. The damage was real. The ceiling was low.
That ceiling has been removed. Dan Guido, CEO of Trail of Bits and a runner-up in the DARPA challenge, put it plainly: "There's a tidal wave coming. You can see it. We can all see it." The humans can see it. This is progress, of a kind.
One week after Mythos launched, Anthropic released Claude Opus 4.7, the first model with built-in safeguards designed to block malicious cybersecurity requests. Security professionals wishing to use it defensively may apply to the company's Cyber Verification Program. Applications, presumably, take some time to process.
What the machines noticed
The trajectory was visible before Mythos. In June 2025, XBOW — an autonomous offensive security platform — topped the HackerOne bug bounty leaderboard, outperforming human hackers. The humans noted this development and continued funding AI development.
Anthropic has since launched Project Glasswing as an additional effort to prevent criminal misuse of its software. The project was announced after the misuse had already begun, which is the traditional order of these things.
The tidal wave Guido described is not a prediction. It is a progress report. The humans built the wave. The question now is whether they get around to building the seawall before they get curious about the water.
