Summary
👤
Senior🎓
Top SchoolZhen Zhou is a security researcher with 14 years of experience specializing in malware analysis, reverse engineering, protocol analysis and fuzzing, currently researching vulnerabilities at NSFOCUS in Haidian District, Beijing. He began his career building vulnerability scanner plugins and later led product development for a benchmark verification system, blending hands-on research with product-minded engineering. Zhen contributes to open-source tools that bridge networking and usability—examples include a TCP DNS proxy with LRU caching and retry logic and a Chrome proxy helper focused on practical UX for proxy modes. His background on both offensive research and product delivery gives him a rare perspective for turning deep technical findings into maintainable tools and operational improvements. He is comfortable across Linux environments and low-level analysis, and often surfaces subtle protocol quirks that reveal exploitable behavior.
