What is CFG? Earlier in 2018 while revisiting the Delay Import Table, I used dumpbin to check the Load Configuration data of a file and noticed new fields in it: <figure omitted>. And at the time of writing this, more fields were added! The first CFGuard caught my attention and I learned about Control Flow Guard, it is a new security feature. To put it simple, it protects the execution flow from redirection – for example, from exploits that overwrite an address in the stack. Maybe they should call it the Security Directory instead. ;-)[…]
