I will be speaking at Defcon 19 in Vegas next saturday, presenting OWASP Hatkit. I will do it jointly with Patrik Karlsson, who presented out of band channeling using sql injection at Defcon 15 a few years back. We have worked hard to implement *tons* of new stuff in the datafiddler, which has been kept under wraps so far. It has been a lot of hard work, but we have made great progress!
