UDP - UNRELIABLE datagram protocol.

About the Challenge

We have been given a pcap file (You can get the file here)

How to Solve?

First i extract the pcap and then import the file into Wireshark. And then check every packet by pressing Ctrl + Alt + Shift + U to follow the UDP stream

If we examine each packet, the data in each packet will form a flag but there are still many parts missing, so to solve this chall there are 2 ways combine each packet manually (Like me :D) or you can create a script to get the flag. In this case i check every packet manually and then you will get the flag
