A little over thirty years ago, an important decision was made by the Supreme Court of the United States. Sony's Betamax Video Tape Recorder, and the time-shifting it enabled, were ruled legal, creating the precedent necessary for countless technological innovations we now use every day. But what if, as it very nearly did, that decision had gone the other way? V& invites you to find out at OpenCTF: DRMageddon.

In OpenCTF, teams compete to solve hacking challenges in a wide variety of categories, including web, forensics, programming, cryptography and reverse engineering. There will be challenges for all skill levels. If you've never played in a capture the flag contest before, please feel free to stop by anyway - we'll explain how it works and do what we can to set set up with a team. Optional preregistration, as well as some tips on what to bring and how to prepare, can be found at OpenCTF.com.

You must have at least one team member attending DEFCON to play OpenCTF. Arrangements for non-local players are none of our business or concern.
