hackyou CTF: Networking 100

They give you a pcap file (Download Here) and tell you to "Find the secret link in this conversation." I opened this in Wireshark and followed what appeared to be some sort or IRC conversation. In tcp.stream 4, I found the following message.

The key was tinyurl.com/8pdox5a, which was also where you were supposed to download the network 300 challenge.
