Beware the ‘son of Mythos,’ security experts warn
Summary
Major AI companies like Anthropic and OpenAI are expanding access to frontier AI models (cutting-edge AI systems) for vulnerability discovery tools like Claude Mythos, which can identify security weaknesses in software. Security experts warn that these tools are becoming cheaper and more capable, and that attackers are already using similar AI systems, so organizations need to prepare for more advanced threats including the ability to chain together multiple medium-severity vulnerabilities into high-impact attacks.
Solution / Mitigation
According to Paul Chichester from the UK's National Cyber Security Centre, "Organisations should improve cybersecurity by hardening access controls and running incident response exercises." Additionally, organizations should "use AI to write better code and look for vulnerabilities" themselves, and ensure their teams can "rapidly validate, prioritize, and remediate the issues being discovered before attackers find them first."
