Top cyber official claims AI hacking tools like Mythos can be beneficial

Top cyber official: The head of the National Cyber Security Centre (NCSC) has stated that advanced artificial intelligence (AI) tools, such as Mythos, can be beneficial for cybersecurity if they are kept secure and out of the wrong hands. Richard Horne, the NCSC chief, emphasized that frontier AI tools have the potential to enhance cyber-defense capabilities significantly.

Top cyber official: what to know

AI Tools and Cybersecurity

AI technologies have gained attention for their capabilities in hacking, particularly with the recent revelations about Claude Mythos, developed by Anthropic. The company has restricted access to this model to assist governments, tech companies, and financial institutions in securing their systems as the cybersecurity community prepares for its eventual release.

Horne described advanced AI tools as a “net positive” for public cybersecurity, provided that measures are taken to prevent misuse. He is advocating for organizations to focus on fundamental cybersecurity practices rather than fearing potential AI-driven attacks. In his upcoming speech at the NCSC’s annual conference, CyberUK, he plans to highlight the importance of addressing existing vulnerabilities that AI can exploit.

Government and Industry Collaboration

UK Security Minister Dan Jarvis is also urging AI companies to collaborate with the government to enhance national cyber-defense capabilities. He referred to this effort as a “generational endeavour” to ensure that AI is utilized to protect critical networks from cyber threats.

Horne’s remarks reflect ongoing concerns about the misuse of powerful AI models, which are primarily developed outside the UK, particularly in the US and China. The reliance on companies like Anthropic for access to tools like Mythos raises questions about control over their development and deployment.

In addition to Mythos, OpenAI has introduced a cybersecurity model known as GPT 5.4 Cyber, which is also noted for its capabilities. The discussions at CyberUK will address the persistent threats posed by nation-state actors and hacktivists, particularly from countries such as Russia and China. The NCSC has underscored that cyber warfare is now a critical aspect of national defense in the UK, as evidenced by recent cyber incidents.
