35c3 SDR Challenge

To finally bring our rad1o to a good use, the Munich CCC is hosting a SDR Challenge during 35C3.

We will set up various wireless challenges, which will mostly be solveable with any SDR. Additionally we have some BTLE setups to play with.

In addition to this page we will be operating a CTF gameserver (link will follow here) with a scoreboard, where you can register as a team.

We want to encourage you to play around with radio waves through the use of SDR. If you have never used a SDR before, it's a great chance to get started - it's easier than many people think. In our challenges you will have to decode certain messages in various modulations and read out the challenge flags. In the Bluetooth Low Energy challenges you will have to open various BTLE locks by either applying a known attack or sniffing codes from the air.

You will need an SDR. For those who do not have an SDR we will provide a limited amount of devices able to solve our challenges for a small deposit.

For one of the BTLE challenges a simple device with BT4.0 interface will be enough, for the others you'll ne a BTLE sniffer like the one form adafruit. We will also have a few of those for you available…

After we've set up the senders at 35c3 we will provide you with the links to the flag server as well as the status page.
