UK Government Hackathons Identify Over 400 Code Vulnerabilities Using Frontier AI Models (infosecurity-magazine.com)

• 407 vulnerabilities identified across nine government departments' public code repositories
• Critical flaws included authentication bypass, data exposure, and remote code execution
• All critical and high-risk issues remediated; no exploitation evidence found
• Project cost only £13,000 in token usage

"The UK Government Cyber Coordination Centre (GC3) ran weekly hackathons where teams used frontier AI models to scan public code repositories across nine departments. They discovered 407 findings including critical flaws such as authentication bypass, data exposure, and remote code execution. Some were zero-days. All critical and high-risk issues were remediated with no evidence of exploitation. The cost was just £13,000 in tokens. A recent US export ban on Anthropic's Mythos and Fable models may impact future events."
