Shellcode Execution Example

This project demonstrates the execution of shellcode using a simple C++ program. The main functionality is implemented in main.cpp.

Overview

The program includes:

• A code array containing shellcode in hexadecimal format.
• A function pointer that points to the shellcode.
• Execution of the shellcode through the function pointer.

Warning

This project is for educational purposes only. Executing arbitrary shellcode can be dangerous and may compromise system security. Ensure you fully understand the code and its implications before running it on your machine.

Files

• main.cpp: Contains the main code for executing the shellcode.

How It Works

1. The shellcode is stored in the code array as hexadecimal values.
2. A function pointer func is assigned to the shellcode.
3. The shellcode is executed by calling the function pointer.

Shellcode Example

char code[] = "\x31\xc9\x51\x68\x2e\x65\x78\x65\x68\x63\x61"
              "\x6c\x63\x89\xe0\x41\x51\x50\xbb\xfd\xe5\xf0"
              "\x76\xff\xd3\x31\xc0\x50\xb8\x4f\x21\xed\x76"
              "\xff\xe0";

Compilation and Execution

Requirements

• A C++ compiler (e.g., gcc or g++).
• A supported operating system.

Compile

To compile the program, use the following command:

g++ main.cpp -o shellcode_exec

Run

Execute the compiled binary:

./shellcode_exec

Expected Behavior

If the shellcode executes successfully, the program returns 0. Otherwise, it returns 1.
