Claude Mythos security testing of internal software
Epic paused some product development to patch security weaknesses found with AI
Problem
Security weaknesses in electronic health-record software could expose sensitive patient information. Epic needed to identify and repair vulnerabilities before attackers exploited them.
Approach
Epic used Anthropic's Claude Mythos model to examine its software for security weaknesses. CEO Judy Faulkner disclosed the findings and said the company paused certain product-development work to implement patches.
Results
No published figures
Takeaway
The findings changed development priorities. Epic did not disclose a measured reduction in security incidents.
