Dan Kaminsky appeared in casual attire at this year's Black Hat Conference. He had just finished a presentation yesterday with an audience of 1,000 people, marking the ninth time he has spoken at the Black Hat Conference in the last ten years. The 29-year-old Dan refers to himself as a DNS expert and earlier today uncovered a serious vulnerability in the DNS system. To prevent major damage to the Internet, he refused to disclose the details of the vulnerability (the DNS vulnerability details were leaked, and attacks are about to begin). Reporter Dean Takahashi from VentureBeat (VB) conducted an interview with Dan Kaminsky (DK) at the Black Hat Conference.
