Course


This lab involves downloading a PCAP file and using Wireshark to analyze a network dump. It focuses on a single HTTP request where the key is available as a GET parameter. By following the TCP stream, you can reconstruct the full connection and inspect the data without worrying about the lower layers like IP and ARP. The video tutorial walks you through the process of identifying the key parameter and understanding the structure of the HTTP request and response, including headers and the actual content.

The exercise starts with loading the PCAP file into Wireshark. You then right-click to follow the TCP stream, which opens a window displaying the full HTTP connection. The video explains how the HTTP request is structured, detailing the method, parameters, headers, and the response from the server. By examining the TCP stream, you will see the key parameter with its value, which is the solution to this exercise. The video also touches on the importance of headers like User-Agent and Host, and how HTTP/1.1 requires a Host header.
