EDR Internals and Bypasses
Endpoint Detection and Response (EDR) product vendors will give you the spiel on what they do and their capabilities, but how do they actually work at the lowest level? And how can we discover weaknesses in these products to develop bypasses or evaluate them?
Join me as we reverse engineer an EDR product and the Windows kernel to unveil its inner-workings, alongside the Windows kernel structures and functions EDR products rely on to operate, and by doing so discover weaknesses and gaps in their protections that allow actors to bypass the product’s defenses, rendering them null&void. Finally, by abusing an identified weakness I’ll use a custom-build mimikatz to dump all the hashes on a machine protected by EDR.
