درود. من یک مطلب کوتاهی نوشتم برای درک پروسهای که توی کرنل رخ میده موقع Null-dereference (معماری x86) و مقداری در مورد Virtual Memory Management کرنل صحبت کردم. شاید برای بچههایی که روی آسیبپذیریهای سمت کرنل کار میکنن هم جالب باشه:

Research into removing strings & API call references at compile-time (Anti-Analysis)
GitHub
An example in C/C++ of how we can remove static string & function call references by using obfuscation paired with runtime function pointers. As a result, static analysis using tools such as IDA or x64Dbg increases in time/difficulty. You may be able to hide specific API calls from anti-malware systems. On the other hand, some AVs might also flag this behavior as being malicious due to there being a lack of "real looking behavior" in the binary.#malware_dev #evasion
