Finally the day arrived and we got to visit DEFCON. It’s been a day we all have been looking forward to, its finally time for the biggest nerd gathering of the year.

The day started warm. We’ve been having around 43 to 45 degrees Celsius down here, so moving outside has been a bit of a challenge. Queues opened at 6 am this year at Defcon, but wisely enough we waited a couple of hours and got our hands on the precious badges at around 9 just in time for the talks that started at 10.

Two very proud security guys in the picture with their long awaited badges. I am sorry @espen, we’ll get your picture tomorrow ^^

Today had only 1 track, the 101 track. This because BlackHat had its final day and is overlapping Defcon’s opening day.

In our first talk we would like to mention we learned a lot about ThinSIM attacks. This is attacks on the ThinSIM feature that resides between the SIM card and the phone processor. It is possible to use exploits and Man in the middle attacks to fool a victim. Fun stuff, although really hard to protect against, as security protection is very limited at that stage in the phone connectivity.

We also attended a talk about How to evade Surveillance teams. This must have been today’s highlight with anti surveillance evasion techniques, with real life demos. Anyone seen the TV Show the Americans? Little did i know that this show actually was based on a true story: https// Anyway and awesome presentation there as well.

The day ended with the Defcon 101 n00b panel. Basically an introduction to DEFCON for all the first time n00bs, like us.

Tomorrow will be another fun day with many great presentations, demos and talks lined up.

We’ll post another blog tomorrow with some more updates.
