Sometime around mid-September (of the last year!) I was tipped off about a new network forensics challenge created by @TekDefense and published on his blog. I was all up for the challenge but I did not have much time back then. Finally, I managed to spend a few evenings just before the due date to perform my analysis of the provided PCAP and document my findings.
Warning: Spoilers ahead! If you did not take the challenge yet, consider going back and trying to solve it by yourself!
