Summary
🤩
Rockstar
Top expert inWindows Kernel and Malware Analysis Technologies
Ayoub Faouzi is a software engineer with 12 years of deep expertise in low-level systems, reverse engineering, and virtualization. He contributes to open-source projects that map CPU internals and anti-analysis techniques, blending practical security tooling with detailed VMX/SVM and MSR knowledge. His work on repositories detecting debuggers, sandboxes, and VMs shows hands-on experience in malware evasion and defensive detection methods, and his headers for Intel/AMD internals reflect strong architectural familiarity with processor virtualization. Notably, he combines security research instincts with systems-level coding—able to move from registry and WMI-based detection logic to precise CPU/VMCS encodings.
