In my experience, open source material like this is too Linux focused. But even with paid courses (doing one of them right now actually) bypassing exploit mitigations and protections is a topic that's hard to find materials on.
Egg hunting, module stomping topics like that with process mitigations turned on and modern edr/ngav running now that I'd pay good money for. In reality, I am trying to drink from the firehose and stumbling around github, customizing poc code and learning that way.
It's really hard to stand a chance at memory exploitation with good edrs and mitigations flipped on.
Another topic that's very important to me is arm exploitation. Azeria labs has good material on it, I haven't finished it to comment on it but there isn't as much material on arm as there is on x86.
You'll also notice most introductory material skips x64 but I'd be interested in x64 intensive material as well. For example, I've learned SEH exploitation multiple times now but it doesn't apply to x64, is it worth the time spent on it? How frequently do you see seh enabled x86 apps these days (genuine question)?
