Our three guys, Sung Dae, Young-Jo, and Donghyuk and the Professor went to Las Vegas to attend the BlackHat and DEFCON Conference.

Black Hat USA is the show that sets the benchmark for all other security conferences. As Black Hat returns for its 17th year to Las Vegas, we bring together the brightest in the world for six days of learning, networking, and skill building.

DEFCON is one of world’s largest annual hacker conventions held every year in Las Vegas, Nevada. It was held at the RIO Hotel and Casino.
