Hi everybody,

our first Scan of the Month Challenge in 2010 is over! We received 91 submissions in total, and some parts of the solutions are so interesting that I would like to publicly highlight them in this post. Now that the winners are announced (Congratulations Ivan, Franck, and Tareq!), I think I also owe you an explanation why we asked the specific questions and what we expected as answers. I am sure you will be surprised how many pieces of information you can dig up in a plain pcap - I was indeed when I had a look at the solutions we received. Enjoy!

First challenge of the Forensic Challenge 2010 has been posted.
