This exercise is one of our challenges to help you learn how to analyze PCAP files

PCAP badge


To get started with this badge, you need to install Wireshark, a powerful tool for network analysis. The lab provides a PCAP file containing network traffic, which you can download and examine using Wireshark. By opening the file and following the TCP stream, you'll be able to reconstruct the full communication between the client and the server, revealing the key transmitted during the session.

In this challenge, you will analyze a single TCP connection where the client sends a specific string to the server. By right-clicking and selecting "Follow" -> "TCP Stream," Wireshark will display the entire conversation, allowing you to focus on the data without dealing with lower layers such as IP or ARP. This lab is an excellent introduction to using Wireshark for network forensics and understanding TCP communications.
