Memory AntiviruZ Evasion

This library is designed to help you avoid antivirus software false positives by dynamically resolving the address(ess) of your desired function(s). As of everything there is potential for misuse, do not abuse it for bad purpose that would be bad ;) (if you get it, you get it)

Usage

Step 1

First things first you call your initialize() function, this step is crucial to load DLLs and get addresses to the required functions provided by these libraries. You shall save the return value of this function in a Maze_Functions struct. If this function fails std::runtime_error is thrown.

Step 2

Then you must get a pointer to the Process Enviroment Block of the current process, this is task is performed by the get_peb function which takes as an argument a constant reference to a the Maze_Functions struct created in the previous step. If this function fails it will return nullptr

Step 3

Next you call get_peb_entries passing the PEB pointer you adquired in the previous step to the function, this will return an std::vector<LDR_DATA_TABLE_ENTRY> object, you can implement your own search algorithm, or use any of the existing STL algorithms however it is recommended you use get_module_base which takes as arguments a constant reference to an object of type std::vector<LDR_DATA_TABLE_ENTRY> and a constant std::wstring , or it's overloaded version which takes 1 pair of iterators and a constant std::wstring, this string contains the name of the module to be found. this function will return a value of type void* which represents the base address of the desired module, in case the module can't be found the return value will be nullptr

Step 4

The final step is calling get_procedure of type void*, which will return the address of the desired function if successful, this address is then to be stored inside a function pointer defined by the programmer and appropriately casted. It's arguments are a void pointer to the base of the module where the desired function comes from(Step 3), a const char* or C-STRING with the name of the exported function and finally a constant reference to the Maze_Functions struct from step number 1.

Example

#include <iostream>
#include "Maze.h"

typedef bool(__stdcall *rpm_ptr)(HANDLE, LPCVOID, LPVOID, SIZE_T, SIZE_T*);
typedef bool(__stdcall *wpm_ptr)(HANDLE, LPVOID, LPCVOID, SIZE_T, SIZE_T*);

int main() {	
	Maze_Functions functions = initialize();
	PEB* peb = get_peb(functions);	
	void* baseaddress = get_module_base(get_peb_entries(peb), L"KERNEL32.DLL");
	if (baseaddress == nullptr) return 0;
	wpm_ptr dWriteProcessMemory_ptr = reinterpret_cast<wpm_ptr>(get_procedure(baseaddress, "WriteProcessMemory", functions));
	rpm_ptr dReadProcesMemory_ptr = reinterpret_cast<rpm_ptr>(get_procedure(baseaddress, "ReadProcessMemory", functions));
  //You can proceed to call the function pointers as normal functions...
  return 0;
  
  }
