h4cked is a different kind of challenge than the CTFs I normally write about. Quite the opposite actually. We’re given the solution up front and are tasked with reverse engineering a hack by analyzing the traffic recorded in a PCAP file, otherwise known as a packet capture. (It’s an extremely detailed log of all inbound and outbound network traffic over a period of time.) After that we’ll use the findings to replicate the hack and root the box. We’ll use Wireshark to conduct our analysis. Let’s get started!
