The Hacker Jeopardy is a quiz show.

The well known reversed quiz format, but of course hacker style. It once was entitled „number guessing for geeks“ by a German publisher, which of course is an unfair simplification. It’s also guessing of letters and special characters. ;) Three initial rounds will be played, the winners will compete with each other in the final. The event will be in German, we hope to have live translation again.

Listening to satellites and decoding is fun. We show interesting stuff we found, and how you can get into it.

The Iridium satellite system provides voice and data coverage to satellite phones, pagers and integrated transceivers over Earth's entire surface. It was built by Motorola over 15 years ago, and parts of it remain unchanged to this day. Last year we showed how to decode the unidirectional pager messages. Since then we can share our better understanding of some of the protocol but also show listening to the SMS-like bidirectional SBD communication channel.

News about the rad1o half a year later – cool stuff that happened, and why you need an SDR.

The rad1o was the badge for the Camp 2015. This talk will be a bit about what went into a project of this size, what went well and what not so much. The main part is about what we (and lots of other volunteers) have done with it – both standalone and with a computer, and why y’all need to play more with SDR.

The chronicles of reversing the Iridium pager system.

The Iridium satellite system provides voice and data coverage to satellite phones, pagers and integrated transceivers over Earth's entire surface. It was built by Motorola over 15 years ago, and parts of it remain unchanged to this day. Iridium pagers are similar to other pager systems from that time (they are receive-only devices) with the benefit that they will work anywhere on earth. Additionally they work on a receiver-pays subscription model, and due to their age are probably not using cryptography. Broadcasting messages all over the world sounds interesting enough to take a closer look. As Iridium is a proprietary system, documentation is scarce and hard to come by. But with the rise of software defined radio we can take a peek at what happens over the air...
