DirectX is the engine that handles rendering on the Windows platform. Many outstanding people have made outstanding contributions in the research of DirectX. In this talk, I will share new research content of DirectX including the discovery of new attack methods, new paths, and how to design targeted fuzz based on these, and find related vulnerabilities. I will also introduce the experience of designing Windows kernel fuzz and explore how to better design closed source fuzz.
