A group of users leaked Anthropic's AI model Mythos by reportedly ...
The AI model that Anthropic billed as too dangerous to release has reportedly been accessed by an unauthorized third party, and the incident raises concerns about the future of cybersecurity. The Mythos model was reportedly accessed by a handful of users in a private Discord chat on the day it was announced publicly, Bloomberg reported. Earlier this month, the group was able to access the program in part because one of the members of the group is a third party contractor for Anthropic, according to Bloomberg. Using this access, the group was able to guess where the model was located based on previously leaked knowledge by another group about Anthropic’s past practices, that hackers obtained from AI training startup Mercor. Although the group that accessed it has not been using the model for cyberattacks, it has been using the program continuously since its release and still has access, the outlet reported. Anthropic did not immediately respond to Fortune’s request for comment. A spokesperson from Anthropic told Bloomberg the company was “investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments.” The fact that the model was leaked so quickly doesn’t surprise David Lindner, the chief information security officer at Contrast Security and a 25-year industry veteran. Even though Anthropic intentionally limited the model to a small group of 40 companies—including Microsoft, Apple, and Google— to beef up their security ahead of a wider release, thousands of people likely had access to the program across these companies, which makes a leak nearly inevitable, he said. “It was bound to happen,” Lindner said. “The more they add to this elite group, the more likely it was to get released to someone who shouldn’t probably have access to it.” Anthropic claims its Mythos model is more adept at finding cybersecurity vulnerabilities than previous versions. The company was able to use the program, which has not been widely released, to find a 27-year-old security vulnerability in OpenBSD, an operating system known for its security. Mozilla on Tuesday also said it used a preview of the model to identify and patch 271 vulnerabilities in its Firefox web browser. And yet, Mythos’ release has been plagued by security breaches from the start. Fortune was the first to report on the model’s existence thanks to a security lapse that exposed details about the large language model in a publicly accessible da...
Anthropic’s most dangerous AI model just fell into the wrong hands | The Verge

Jess started her career at TechRadar, covering news and hardware reviews.Anthropic’s Mythos AI model, a powerful cybersecurity tool that the company said could be dangerous in the wrong hands, has been accessed by a “small group of unauthorized users,” Bloomberg reports. An unnamed member of the group, identified only as “a third-party contractor for Anthropic,” told the publication that members of a private online forum got into Mythos via a mix of tactics, utilizing the contractor’s access and “commonly used internet sleuthing tools.”The Claude Mythos Preview is a new general-purpose model that’s capable of identifying and exploiting vulnerabilities “in every major operating system and every major web browser when directed by a user to do so,” according to Anthropic. Official access to the model is limited to a handful of companies through the Project Glasswing initiative, including Nvidia, Google, Amazon Web Services, Apple, and Microsoft. Governments are also eyeing the technology. Anthropic currently has no plans to release the model publicly due to concerns that it could be weaponized.“We’re investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments,” an Anthropic spokesperson said in a statement to Bloomberg. Anthropic currently has no evidence that the unauthorized access is impacting the company’s systems or goes beyond the third-party vendor’s environment.The model was reportedly accessed illicitly on April 7th, the same day that Anthropic announced it was releasing Mythos to a limited number of companies for testing. The group that gained the unauthorized access has not been publicly identified, though Bloomberg reports that its members are part of a Discord channel that seeks out information about unreleased AI models.The group accessed Mythos by using knowledge of Anthropic’s other model formats obtained from a recent Mercor data breach to make “an educated guess” about its online location. Members have been using Mythos regularly since gaining access — providing screenshots and a live demonstration of the model as evidence to Bloomberg — though reportedly not for cybersecurity purposes in an attempt to avoid detection by Anthropic. Other unreleased Anthropic AI models have also been accessed by the group, according to Bloomberg.Follow topics and authors from this story to see mo...
