Summary
👤
Senior🎓
Top SchoolJessy Campos is a Senior Security Engineer with 11 years of hands-on experience in binary analysis, vulnerability research, exploit development, and Windows internals, currently at Microsoft after leading game security efforts at Ubisoft. He has deep expertise in anti-cheat, software protection and hypervisor-related research, and has leveraged undocumented Windows mechanisms to bypass modern defenses. An accomplished conference speaker (REcon, BlueHat, 33c3, BotConf) and credited for CVEs from his time at ESET, he blends threat intelligence and malware analysis with practical R&D. On open source, he significantly improved performance and cross-architecture support for the popular Triton dynamic binary analysis library, focusing on memory management and instruction caching—demonstrating a rare mix of low-level research and production-grade performance engineering.
