A misconfigured content management system exposed roughly 3,000 unpublished digital assets from an AI company’s website, including a draft blog post describing an unreleased, unusually capable model internally codenamed “Capybara” and marketed as Claude Mythos. The leaked draft said the model represented a major jump in autonomous vulnerability discovery and remediation, raising fears it could undercut human-run cybersecurity services. Within a day of the leak on March 27, 2026, roughly $14.5 billion in market value was wiped from cybersecurity stocks including CrowdStrike, Palo Alto Networks, and Zscaler.
