Rich Kelley (@RGKelley5) is a security researcher and the co-founder of Gray Tier Technologies, a small InfoSec start-up based out of Alexandria, VA. After his time in the military he held positions as a network engineer, software engineer, and penetration tester for various government agencies. He recently moved into exploit development and reverse engineering, and is pretty sure he knows less than when he started. Twitter: @RGKelley5
