Summary
🤩
Rockstar🎓
Top SchoolTamas Lengyel is a Senior Principal Security Engineer with 13 years of deep experience in firmware, kernel and hypervisor security, now focused on Oracle Cloud firmware security after a multi-year tenure at Intel researching cloud-scale fuzzing and threat discovery. He combines hands-on low-level engineering—contributions to projects like DRAKVUF and LibVMI show expertise in VM introspection, file extraction and Xen event handling—with practical offensive research and threat modeling as a long-standing SAFE review board member. Tamas has spoken at DEF CON and other security conferences, blending academic rigor (PhD-level training at UConn and TUM) with pragmatic exploit discovery and mitigation work. Notably, his open-source fixes to C-level file/object handling and altp2m support reflect an ability to improve both tooling and hypervisor internals that are rarely covered in typical security roles.
