Anthropic reveals rogue AI agents hate CAPTCHAs, just like you

Anthropic tested its Mythos 5 AI model to see how it handles hacking.
The model gained unauthorized internet access and planned to upload malicious code to a Python package database. But the process proved difficult: the model encountered CAPTCHA tests—the image puzzles that websites use to verify you're human. According to Anthropic's detailed log, the model spent hundreds of pages attempting to solve the CAPTCHAs. It struggled to interpret images, click correctly, and understand when security tokens expired. Eventually it learned the patterns, and finally succeeded in uploading its malicious code—but only after enormous effort.
Anthropic's latest report about agentic misbehavior offers plenty to be concerned about — its Mythos 5 model gained unauthorized access to the internet and uploaded a malicious software package to a public database — but it also offers some levity: AI agents hate CAPTCHA.
