PicoCTF - Shark on Wire 1

This is a challenge from picogym called Shark on Wire 1. The name suggests it's related to Wireshark.

You can find the challenge here

The challenge gave us a pcap file named capture.pcap. I opened it in Wireshark, and the packets were displayed.

I scrolled through for a bit, thinking about how to approach the analysis. I decided to focus on sorting the protocol to specifically identify TCP/UDP packets.
