Chinese cybersecurity firm 360 Security Technology has launched two AI tools to rival Anthropic’s Mythos, aiming to close the gap with Western systems. The tools, Tu Long Feng and Yi Tian Zhen, use an agent-based approach to automate vulnerability hunting and cyber defense. Founder Zhou Hongyi frames the development as a matter of cyber-nuclear deterrence, emphasizing the need for China to build its own strategic deterrent. This move is significant because it highlights the escalating AI arms race between China and the US, with major implications for global cybersecurity. Why it matters: the development of these AI tools marks a crucial step in China’s efforts to challenge US dominance in the field, and could have far-reaching consequences for the future of cybersecurity.
