WinInt Compilation
WinInt stands for Windows Internals, a recopilation of blogs that I will be creating focused on windows reversing, anti-virus bypass and some kernel exploiting in HEVD.
Virtual Machine (Reversing x86)
A small challenge with a virtualized function. It is not designed to be overly difficult. Instead, it is designed to give you something simple to practice on. No fancy dynamic obfuscations or static analysis protections -- just the VM. There is no flag, just working input and non-working input.
Manually Unpacking UPX | PE & PE+ (x86/x64 Tips)
In this mini-post, we will learn how packers like upx works and differents ways to unpack them, focusing in PE/PE+ windows binaries. Learning new concepts such as Thunk, FThunk, IAT and new x32 assembly instructions and their possible variant in x64 architecture (pusha, pushad, popa, popad). All of this applying tools such as x32dbg, x64dbg, IDA Pro, Detect It Easy, Scylla v0.9.8 and more!
