This is from AccessDenied CTF 2022 and its called Shark1. In this challenge we have a pcap file (which is a captured network traffic) and we need to find a flag in it. I'll show you how to open the pcap file using the Wireshark Network Traffic Analyzer and then share with you my tricks to find what we are looking for, faster.
At the end we will use the XOR key we found against the Code and this will decode the flag.
