The talk aims to tackle Windows Heap Manager internals such as Backend vs Frontend Allocators, VirtualAlloc, heap memory layout, Windows 10 vs Windows 7 Heap Manager differences and Windows Heap Integrity protection. We will also explore heap exploit principles for Use-after-free and Double Free exploits like primitives, allocators, precise heap spraying, stack pivot and ROP chaining. In a future part 2 of the presentation, we will dive into more advanced techniques related to memory information leak, type confusion, abusing vtable pointers and Windows ATP protection bypasses. 19:45 → 20:00 ⏸ Break 20:00 → 20:45 🕶 Opsec guide for the security enthusiast 📣 Dan Demeter - Security Researcher @ GReAT, Twitter: @_xdanx 📣 Marco Preuss - Director @ GReAT, Europe, Twitter: @marco_preuss As more and more metadata is passively collected at a large scale, one might question the boundaries set by governments in regards to privacy and personal life.
