Poacher Turned Gamekeeper - Lessons Learned from Eight Years of Breaking Hypervisors
Explore the world of hypervisor security in this 54-minute Black Hat conference talk by Rafal Wojtczuk. Delve into eight years of experience breaking hypervisors, examining vulnerabilities that have led to break-outs in popular systems. Gain insights into four previously undisclosed vulnerabilities and understand the trade-offs between security and functionality in hypervisor design. Compare the attack surfaces of hypervisors with user mode applications and operating system kernels, and learn why many hypervisors aren't inherently secure. Discover real-world examples of hypervisor break-outs, and acquire valuable lessons and recommendations for improving hypervisor design and hardening techniques. Engage with topics such as shared folders, delusional boot, guest PV drivers, device emulation, DMA attacks, and more in this comprehensive exploration of hypervisor security challenges and solutions.
