PANews reported on April 23 that 23pds, Chief Information Security Officer of SlowMist, posted on the X platform that the hacker group ShinyHunters claims to have compromised internal systems related to the Anthropic Mythos model and shared screenshots of user management panels, AI experiment dashboards, model performance and cost analyses. The veracity of this claim has not yet been officially confirmed. Given the large number of companies that have applied for trials, if true, this could pose indirect security risks to leading technology companies and companies in the encryption industry.
