I’ll say this: I did a small lab in college for a hardware security class and I got a scary email from IT because CrowdStrike noticed there was some program using speculative execution/cache invalidation to leak data on my account - they recognized my small scale example leaking a couple of bytes. Pretty impressive to be honest.
Those able to write and use FUD malware do not create public documentation. Crowdstrike is not impossible to bypass, but for a junior security journeyman known as a pentester, working for corporate interests with no budget and absurdly limited scopes under contract for n-hours a week for 3 weeks will never be able to do anything as simple as an EDR evasion, however if you wish to actually learn the basics the common practitioner of this art please go study the offsec evasion class. Then go read a lot of code and syscall documentation and learn assembly.
I don't understand why you were downvoted. I'm interested in what you said. When you mentioned offsec evasion class, is this what you mean? It seems pretty advanced.
What kind of code should I read? Actually, let me ask this, what kind of code should I write first before diving into this kind of evasion technique? I feel I need to write some small Windows system software like duplicating Process Explorer, to get familiar with Win32 programming and Windows system programming, but I could be wrong?
I think I do have a study path, but it's full of gap. I work as a data engineer -- the kind that I wouldn't even bother to call myself engineer /s
I know quite a few offensive security pros that are way better than I will ever be at breaking into systems and evading detections that can only barely program anything beyond simple python scripts.
It’s a great goal to eventually learn everything, but knowing the correct tools and techniques and how and when to use them most effectively are very different skillsets from discovering new vulnerabilities or writing new exploit code and you can start at any of them.
Compare for instance a physiologist, a gymnastics coach, and an Olympic gymnast. They all “know how the human body works” but in very different ways and who you’d go to for expertise depends on the context.
Similarly just start with whatever part you are most interested in. If you want to know the techniques and tools you can web search and find lots of details.
If you want to know how best to use them you should set up vulnerable machines (or find a relevant CTF) and practice. If you want to understand how they were discovered and how people find new ones you should read writeups from places like Project Zero that do that kind of research. If you’re interested in writing your own then yes you probably need to learn some system programming. If you enjoy the field you can expand your knowledge base.
is there any writeups from the pentesting side of things that we can read to learn more?
