   Top white-hat Yuki Chen joins Zhipu as GLM earns credit for 23 Microsoft vulnerabilities

   Veteran security researcher Yuki Chen (Chen Xuebin, known in Chinese security circles as Gu He) announced on X on October 14 that he has joined Zhipu (Z.ai) to work on cybersecurity with frontier AI, a move welcomed by Zhipu Z.ai head Li Zixuan. Microsoft's MSRC credited 23 vulnerabilities found with GLM-assisted research, including one rated CVSS 9.8, with the public record naming "Yuki Chen using GLM from z.ai". Zhipu says GLM-5.3 scored 84.5% on the CyberGym benchmark versus 77.2% for GLM-5.2; an Anthropic report dated September 29 said GLM-5.3 can autonomously build end-to-end exploits, succeeding in 50 of 410 ExploitBench attempts against 56 for Claude Mythos Preview, while NIST's CAISI rated it the strongest open-weight model for cybersecurity at the time but roughly four months behind leading US frontier models.
