Security Chinese cybersecurity company claims it’s built a better-than-Mythos bug finder Qihoo 360, which the US has banned, says it’s needed as a deterrent to weaponized Anthropic models Simon Sharwood Simon Sharwood APAC Editor Published fri 26 Jun 2026 // 02:49 UTC Chinese cybersecurity vendor Qihoo 360 claims it’s built an AI bug-finder that’s better than Anthropic’s Mythos model. CEO Zhou Hongyi revealed the model in a speech at the 14th Beijing Cybersecurity Conference, which Qihoo 360 organizes. Chinese media outlets have transcribed the talk, in which Zhou described Mythos as “equivalent to a ‘cyber nuclear weapon’,” because the USA’s ban on foreign nationals accessing the model gives America a tool with which to find flaws in software upon which other nations rely. Zhou thinks China needs equivalent capabilities as a deterrent, but suggested replicating Mythos is not a viable approach. REG AD “Mythos follows a typical large-scale model approach: the strongest model, the strongest computing power, and the strongest chips – a strategy of sheer brute force,” he said. “However, this path has an implicit prerequisite: your model capabilities must be sufficiently strong. Objectively speaking, domestically developed models still lag behind by 20 percent to 30 percent in underlying capabilities.” REG AD The CEO therefore thinks China can’t wait for its own models to catch up and needs to find another way to build Mythos-grade bug-finders. Helpfully, Qihoo 360 has found those alternative methods by distilling its 20 years of experience fighting cyber-threats and colossal malware library into security-specific models and agents. The company has put that to work in what Zhou described as a “multi-agent swarm.” MORE CONTEXT Mythos discovers 'Squidbleed,' a memory leak that's gone undetected since Clinton era Five Eyes spooks warn AI means infosec incidents can become ‘major operational and financial crises’ Anthropic's Mythos mess just keeps getting more complicated Fe
