Finding Hidden data from a UDP packets destination port
A clever and fun idea in the Elbonia Challenge from PatriotCTF 2023. We have a pcap file which contains a hidden message. In the beginning I will examine it using WireShark and after finding the clue (and a few reroutes I will describe in the video) will extract the flag using the scapy python library and IDLE.
