China’s largest cybersecurity firm just fired a shot across the bow of one of America’s most powerful AI companies. 360 Security Technology announced two AI-driven cybersecurity tools, Tulongfeng and Yitianzhen, positioning them as a direct answer to Anthropic’s Claude Mythos, the system that sent shockwaves through the security world when it was revealed in April.

When Anthropic unveiled Mythos on April 7, the system could autonomously discover and exploit thousands of zero-day vulnerabilities across major operating systems and browsers. Anthropic opted not to release it publicly. Now 360 is claiming it has built tools that can match those capabilities.

What 360 actually built

Tulongfeng handles automated vulnerability discovery. Yitianzhen takes the other side of the equation: automated cyber defense and incident response.

360 isn’t exactly coming to this cold. During a contest in April, the company reported that its AI-driven methodologies detected approximately 1,000 vulnerabilities in systems like Microsoft Office.

Eugenio Benincasa, an analyst at ETH Zurich, has noted 360’s emergence as a direct competitor to Mythos.

The geopolitical chess match

Chinese cybersecurity firms’ stocks, including 360, saw a rise in April following the Mythos announcement. The market read the situation correctly: rising demand for AI security solutions was coming, and domestic players would be the beneficiaries in China’s market.

What this means for investors

The risk factor worth watching is verification. Anthropic demonstrated Mythos’ capabilities in controlled settings before deciding not to release it publicly. 360’s claims about matching those capabilities haven’t been independently tested in comparable scenarios. The gap between detecting 1,000 vulnerabilities in Microsoft Office and autonomously exploiting zero-day chains across operating systems is enormous.
