MagmaGate (inspired by Hell's/Halo's Gate)

MagmaGate is my version of Hell's/Halo's Gate, following similar principles of both

MagmaGate does the following:

Walk the PEB (used to grab Ntdll Base Address)

Grab a function pointer to the Export Address Table (EAT)

Get Base Hash --> API Hashing function using the export directory as a seed

GrabSSN --> Used to grab both the SSN and Syscall Instruction Address of an Unhooked Function

SSNUnhook --> Same as GrabSSN but for Hooked Functions

relative_jmp --> used to detect any jmp instructions (hooks)

absolute_jmp --> used to detect any inline hooking

MagmaGate --> Ties everything together and grab all the necessary information

Example of NtWriteVirtualMemory

Obviously I did not create this myself, nor am I claiming to be.

That being said, credit where credit is due, these are all the sources I used to create MagmaGate
