Anthropic’s Mythos Preview AI model, a tool renowned for its ability to detect security vulnerabilities in software and networks, has been so powerful that its release has been carefully controlled by its creator. However, a group of amateur detectives on Discord discovered their own relatively simple methods—without the need for AI hacking—to gain unauthorized access to Mythos itself.

Despite Anthropic’s attempts to regulate who can use Mythos Preview, a group of Discord users managed to access the tool through some relatively simple detective work. They analyzed data from a recent breach of Mercor, an AI training startup that collaborates with developers, and made an educated guess about the model’s online location based on Anthropic’s format for other models. This phrase has led many to speculate that it refers to a web URL, according to Bloomberg, which first reported the story.

The individual also reportedly leveraged permissions they already had to access other Anthropic models, due to their work for an Anthropic contracting firm. As a result of their investigation, they allegedly gained access to not only Mythos but also other unreleased Anthropic AI models. Fortunately, according to Bloomberg, the group that accessed Mythos has so far only used it to build simple websites—a decision made to avoid detection by Anthropic—rather than to hack the planet
