We are given an objective for the packets series: “Part 1. Find the secret link in this conversation.” We have a .pcap capture file and we simply apply a filter to the captures.
filter: "data-text-lines contains "key" message=oh%2C%20sry.%20key%20is%20tinyurl.com%2F8pdox5a&to=%23hacku
Decoding the url encoded string yields the message: “oh, sry. key is tinyurl.com/8pdox5a”.
