An anonymous group of Discord users says it hacked its way into accessing Claude Mythos Preview, the new AI model Anthropic claims is too powerful for a public release. Anthropic says Claude Mythos "is capable of identifying and then exploiting zero-day vulnerabilities in every major operating system and every major web browser," and has granted access to the model to a select group of partners via an initiative called Project Glasswing. As Bloomberg reports, the Discord users gained access by guessing the online location for the model based on past Anthropic naming conventions — as found in the recent data breach at Mercor, an AI startup, earlier this month. One member of the group already had privileged access as a worker at a third-party contractor for Anthropic. The group was part of a private Discord channel that focuses on hunting information about unreleased models. A member told Bloomberg they were not using Claude Mythos for nefarious purposes, but for tasks like building simple websites, and claimed to have access to even more unreleased Anthropic models. Anthropic confirmed in a statement to Bloomberg it was aware of the claim and investigating. At this time, there is no indication that Claude Mythos has been breached by other unauthorized parties.
