Summary
🤩
Rockstar🎓
Top SchoolStephan Van Schaik is a Principal Consultant and Ph.D. graduate in Computer Science & Engineering with 13 years of hands-on experience dissecting CPU microarchitecture, reverse engineering firmware and hardening trusted execution environments across Intel, AMD and Arm platforms. He blends deep academic research on speculative and transient execution attacks with practical systems engineering—writing cross-platform Rust, C, and Python software that targets everything from UEFI and STM32F1 microcontrollers to WebAssembly and Apple Silicon. Known for peering into components others treat as black boxes, he has published undocumented findings on buffers and ports in modern CPUs and built browser-capable cache-attack frameworks. Stephan’s work couples low-level assembly expertise and debugging toolchains with applied security consulting, helping clients translate obscure hardware vulnerabilities into concrete mitigations. An avid explorer of underdocumented hardware features, he also experiments with GPU and graphics-layer instrumentation, often leveraging Vulkan and OpenGL for novel tooling and overlays.
