ULTIMATE TUTORIAL STEAL COOKIES FULL GUIDE

[8]

Stealing Cookies with WiresharkStealing cookies using Wireshark involves capturing network traffic to intercept session cookies, which can then be used to hijack user sessions. Here’s a step-by-step guide on how to do it:
Prerequisites

1. Wireshark Installed: Ensure Wireshark is installed on your system. You can download it from the official website.
   
2. Network Access: You need to be on the same network as the target or have access to the network traffic between the target and the server.
   

Steps to Steal Cookies

1. Start Wireshark:
   • Open Wireshark and select the network interface that is connected to the network you want to monitor.
     
2. Enable Promiscuous Mode:
   • Put your network interface into promiscuous mode to capture all traffic visible on that interface, including traffic not destined for your machine. This can be done within Wireshark by right-clicking on the interface and selecting "Options," then checking "Capture packets in promiscuous mode" .
     
3. Capture Network Traffic:
   • Start capturing packets by clicking the shark fin icon or pressing 
     Code:

     Ctrl+E
     . Wireshark will begin displaying packets in real-time.
     
4. Filter HTTP Traffic:
   • To focus on HTTP traffic, which often contains cookies, apply a display filter. For example, use the filter 
     Code:

     http
      to show only HTTP packets .
     
5. Identify Cookie Packets:
   • Look for packets that contain cookie information. Cookies are typically found in the HTTP header. You can expand the HTTP packet details to view the headers and look for 
     Code:

     Cookie:
      or 
     
     Code:

     Set-Cookie:
      fields.
     
6. Extract Cookies:
   • Once you identify a packet containing a cookie, you can extract the cookie value. Right-click on the packet, select "Follow" > "TCP Stream" to view the entire conversation, including the cookie exchange.
     
7. Save the Cookie:
   • Copy the cookie value and save it for later use. This cookie can now be used to hijack the user’s session.
     

Example WalkthroughLet’s say you want to steal a session cookie from a user logging into a web application.

1. Start Wireshark and select your network interface.
   
2. Enable Promiscuous Mode on the interface.
   
3. Start Capturing packets by clicking the shark fin icon.
   
4. Apply Filter: Use the filter 
   
   Code:

   http
    to focus on HTTP traffic.
   
5. Identify Login: Look for HTTP POST requests that indicate a login attempt. These requests often contain form data, including usernames and passwords.
   
6. Follow TCP Stream: Right-click on the login request packet and select "Follow" > "TCP Stream" to view the entire login process.
   
7. Extract Cookie: In the TCP stream, look for the 
   
   Code:

   Set-Cookie:
    header in the server’s response. This header will contain the session cookie.
   
8. Save the Cookie: Copy the cookie value and save it.
   

Using the Stolen CookieOnce you have the cookie, you can use it to hijack the user’s session by adding it to your browser’s cookie store for that domain. This can be done manually or using browser extensions designed for cookie management.
