CTF for beginners: Using wireshark to sniff secrets and then decode them with a Key

preview_player
Показать описание
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.

Loved you demonstration, have a similar CTF I am dealing with, everything you showed was relevant so far, beside the XOR, can not find anything that might be used as a key for XORing

Hello, I have this homework now. There are more than 60000 packets in the file I received from instructor. How to know in which packet is the flag?
