Winner and solution of TheHexFactor sample challenge

The first person to answer the challenge completely was Philippe Teuwen. Kudos for solving this challenge the day itself. Since he already has a ticket, he receives a Tshirt and prices will go to the runner-up Mark Hillick!

For those who wondered what the correct answer was, here is the solution:
  • Hidden.rtf is hidden in vader.gif using steganography with the IDEA encryption protocol. Using the passphrase "hexfactor" the file can be extracted.
  • Hidden.rtf contains the following url :
  • Poodleman.jpg metadata contains UHJpbnNlbmdhbGVyaWosIEJydXNzZWwsIEJlbGdpdW0=
  • The base64 string contains the following information : Prinsengalerij, Brussel, Belgium
  • With Google Maps, you can find the location and retrieve pictures taken nearby. The famous statue is among them : Jeanneke Pis
  • With, you can find out which sites also host the poodleman pictures :

For those who want to have more fun and learn new stuff.... come over to BruCON and play TheHexFactor! The venue will stay open all Friday evening so you can play after the last presentations to your hearts content.

OMG we have been hacked. OH: Not really

Today, some people on the internet discovered the properties of a wiki: editing pages. Just like the Chaos Communication Conference (CCC) and other similar conferences, we deployed a wiki so that users could actively contribute to the conference. Schedule workshops, share traveltips, help us make wallpapers and upload them etc... etc...

Although critical pages are locked down, a lot of pages can be used by our volunteers and visitors. That's the nature of a wiki and the purpose is to be interactive with the community. The downside is that sometimes people misinterpret this as the possibility to do evil and vandalism. Like @securityshell discovered today.

Yes, although we have quite good antibot protection, we are not protected against these kind of people. We could lock the wiki further down, but that is against the open nature of our wiki. It only wastes the time of our wikiadmin who is a volunteer by itself with a real full-time job and hobbies.

Making text insertions and putting iframe code in it (which displays as normal text) and doesn't work and taking screenshots of it on your blog, claiming our website contains malware, well, is not much proof at all. If you know anything about mediawiki is that you can't insert code like that. Above all, it's a total waste of time, of you, of us. We can assure you, no harm was done except wasting the time of our wikiadmin to undo some wiki vandalism. We would hate it to make the wiki less accessible. Go to wikipedia, the 26C3 or the 27C3 wiki soon and have fun there as well. It won't make you a lot of friends in the community. So please stop.

Best Regards
The sysadmin
