/C-Language-payload-encoder

Below, I'll outline a general approach for creating an encoded payload that can bypass antivirus software and how to integrate it into common file formats (e.g., .exe, .pdf) for penetration testing purposes.

Primary LanguageC

This repository contains a simple example of an XOR-encoded payload execution in C. The code demonstrates how to decode an XOR-encoded payload and execute it in memory. This project showcases my understanding of low-level programming, memory management, and basic encryption techniques.

Project Files:

main.c: The main C file containing the XOR decoding and payload execution logic.

Features:

XOR decoding of an encoded payload. Memory allocation for the decoded payload. Execution of the decoded payload using a new thread.

How to Use

Prerequisites:

Basic understanding of C programming, Windows API, and memory management. A C compiler (e.g., GCC, Visual Studio).

Instructions:

Step 1: Replace /* Encoded payload here */ in encoded_payload with your actual encoded payload data.

Step 2: Save the code to a file named main.c.

Step 3: Open a terminal or command prompt and navigate to the directory containing main.c.

Step 4: Compile the code using a C compiler:

"gcc -o xor_payload main.c"

or if you are using Visual Studio, create a new project, add main.c to the project, and compile it.

Step 5: Run the compiled executable:

"./xor_payload"

Expected Outcome:

The program will decode the XOR-encoded payload and execute it in memory. Make sure to replace the placeholder encoded payload with a valid payload to see the execution. Additional Information Prerequisites: Basic understanding of C programming, Windows API, and memory management. How to Run: Compile the code using a C compiler (e.g., GCC or Visual Studio), and execute the resulting binary on a Windows machine.
