A group of unauthorized users has reportedly gained access to Mythos, the cybersecurity tool recently announced by Anthropic.

Much has been made of Mythos and its purported power — an AI product designed for enterprise security that, in the wrong hands, could become a potent hacking tool, according to the company. Now Bloomberg has reported that a “private online forum,” the members of which have not been publicly identified, has managed to gain access to the tool through a third-party vendor.

“We’re investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments,” an Anthropic spokesperson told TechCrunch. The company said that, so far, it has found no evidence that the supposedly unauthorized activity has impacted Anthropic’s systems in any way.

The unauthorized group tried a number of different strategies to gain access to the model, including using “access” enjoyed by the person who was interviewed by Bloomberg. That person is currently employed at a third-party contractor that works for Anthropic, the outlet reported.

Members of the group are part of a Discord channel that seeks out information about unreleased AI models, the outlet reported. The group has been using Mythos regularly since gaining access to it, and provided evidence to Bloomberg in the form of screenshots and a live demonstration of the software.

Bloomberg reports that the group, which supposedly gained access to the tool on the same day it was publicly announced, “made an educated guess about the model’s online location based on knowledge about the format Anthropic has used for other models.” The group in question is “interested in playing around with new models, not wreaking havoc with them,” the source told the outlet.
