31C3 Title, no sound Alright, welcome! It's great to be here! So many people, although it is very late. I've been told, that this is the prime time. That is awesome, at 11 p.m. I'm David, I'm a Computer Scientist from Bonn. And we just can start with the things that happened so far at the congress. If you happened to be here at the congress or watched sessions on stream - welcome again to the colleagues on the internet - then there will be always devices that one does not like so much to use. [Laughter] Who participated in the sessions of Tobias Engel and Karsten Nohl, does indeed use his mobile phone less confident. And who was with starbug afterwards, will not like to use iris scanners or finger print scanners anymore and may use gloves more frequently now. So here a little disclaimer: If someone has an intimate relation to his photocopier and tends to keep it like that, should refrain from participating this session. We will do three things during this session. First of all we will get to know one of most prevalent and dangerous bugs of the last years. Secondly, we will comprehend the bug. That is in a manner nerds and muggels will understand. And last but not least, for the activists among us - may be some present here - we will deduct some rules that may apply to a single person that will handle a powerful opponent, just like a global player. But in your case it can be something completely different. That's why I will describe precisely how this dispute evolved over time.
