RAT Client and C2 Server - Ultimate Covert Command & Control Toolkit 🚀

Welcome to the ultimate covert Command & Control (C2) toolkit! This repository is a comprehensive suite for those who are keen on mastering the art of stealthy communication and control over remote systems. Designed with advanced techniques in mind, this toolkit provides everything a sophisticated hacker needs to establish an undetectable command channel between the client and server.

Features

🛡️ Advanced Anti-Debugging and Anti-VM Techniques

• Bypass conventional debugging attempts with robust anti-debugging mechanisms.
• Detect and evade virtual machine environments to ensure your client runs undetected on genuine targets.

🔒 Strong AES Encryption

• Secure your communications with AES encryption, ensuring that all data transferred between the client and server is completely secure and unreadable to prying eyes.

📨 Stealthy ICMP Communication

• Use ICMP packets for covert communication. Avoid detection by standard network monitoring tools and firewalls with this sophisticated method of data transfer.

🎭 Polymorphic Shellcode Mutation

• Evade signature-based detection systems by continuously altering the shellcode. This polymorphic approach ensures that your payload remains undetected and effective.

💡 Dynamic Code Loading

• Load and execute code dynamically from files, allowing for easy updates and expansions of functionality without the need to redeploy the client.

🛠️ Command Execution

• Execute arbitrary shell commands received from the C2 server, giving you full control over the remote system.

How It Works

Client

• Implements anti-debugging and anti-VM checks.
• Encrypts and decrypts messages using AES.
• Sends and receives ICMP packets to communicate with the C2 server.
• Executes commands as directed by the C2 server.

Server

• Listens for ICMP packets and decrypts incoming commands.
• Sends commands to the client to be executed.
• Uses AES encryption to ensure secure communication.

Usage

Compilation and Setup

1. Compile the RAT Client:

   gcc rat_client.c -o rat_client -lssl -lcrypto

2. Run the RAT Client (requires root privileges):

   sudo ./rat_client <command>

3. Run the C2 Server:

   sudo python3 c2_server.py

Automation

• Scripts are provided to automate the compilation, execution, and communication process, making it easy to deploy and manage.

Detailed Code Explanation

RAT Client Code (rat_client.c)

• Includes and Defines:

  • The necessary libraries for network communication, encryption, and system operations are included.
  • AES_KEY and ICMP_PAYLOAD_SIZE are defined for AES encryption and ICMP packet payload size.

• Obfuscation Functions:

  • obfuscate_string and deobfuscate_string use XOR and bitwise operations to obfuscate and deobfuscate strings.

• Anti-Debugging Function:

  • anti_debug uses inline assembly and checks for debugging environments. It attempts to detect if the process is being debugged and exits if so.

• Shellcode Mutation Function:

  • mutate_shellcode mutates the shellcode to make it harder to detect by signature-based defenses.

• AES Encryption/Decryption Functions:

  • aes_encrypt and aes_decrypt perform AES encryption and decryption using the OpenSSL library.

• Checksum Function:

  • checksum calculates the checksum for ICMP packets.

• ICMP Functions:

  • send_ping sends an ICMP ECHO request to a target IP with an encrypted message.
  • receive_ping listens for ICMP ECHO replies and prints the received message.

• Persistence Setup:

  • setup_persistence sets up persistence by copying the RAT executable to a hidden location and appending it to the bash profile.

• Task Execution:

  • execute_task performs encryption, decryption, and other tasks based on the command-line arguments.

• Main Function:

  • The main function handles anti-debugging, persistence setup, and executes tasks based on arguments. It also demonstrates shellcode mutation and sends an encrypted message using ICMP.

C2 Server Code (c2_server.py)

• Encryption/Decryption Helpers:

  • pad and unpad handle padding for AES encryption.
  • encrypt and decrypt perform AES encryption and decryption.

• ICMP Socket Functions:

  • create_icmp_socket creates a raw socket for ICMP communication.
  • receive_icmp listens for incoming ICMP packets and extracts the message.
  • send_icmp sends an ICMP reply with an encrypted message.
  • calc_checksum calculates the checksum for ICMP packets.

• Main Function:

  • The main function sets up the ICMP socket and enters a loop to receive and respond to ICMP packets. It decrypts incoming messages and sends encrypted responses.

Compile Script (compile_rat.sh)

• Compiles the RAT client C code using gcc and links OpenSSL libraries.

Run Server Script (run_server.sh)

• Starts the C2 server with necessary privileges.

Run RAT Client Script (run_rat.sh)

• Executes the RAT client with a provided command.

Automation Script (automate.sh)

Encrypting Data

To encrypt data using the AES encryption method:

unsigned char plaintext[64] = "Sensitive data";
unsigned char ciphertext[64];
aes_encrypt(plaintext, AES_KEY, ciphertext);
printf("Encrypted: %s\n", ciphertext);

Decrypting Data

unsigned char ciphertext[64] = "EncryptedData";
unsigned char plaintext[64];
aes_decrypt(ciphertext, AES_KEY, plaintext);
printf("Decrypted: %s\n", plaintext);

### FAQ
```markdown
## FAQ

### What is a Remote Access Tool (RAT)?
A Remote Access Tool (RAT) is a type of software that allows a remote operator to control a system as if they have physical access to it.

### Is this toolkit legal to use?
This toolkit is intended for educational purposes and authorized security testing only. Misuse of this software can result in severe legal consequences. Always obtain proper authorization before using it on any network or system.

### How does the anti-debugging technique work?
The anti-debugging techniques used in this toolkit involve various methods like inline assembly to detect and prevent debugging attempts, as well as checks for parent process ID and use of ptrace.

### How does ICMP communication help in stealth?
ICMP communication is often used in network diagnostics (like ping). Using ICMP packets for data transfer can help evade detection by standard network monitoring tools and firewalls.
