The offensive security research community has evolved from a relatively small and insular group to a large and vocal group with a wide variety of motives, opinions and skill levels. Adobe’s Brad Arkin said the best way for researchers to make a real mark in the industry is to bring their talents to bear on defensive technologies. He said the vast majority of the new attack techniques that have been deployed by malicious actors in the last few years are directly attributable to research done by the legitimate offensive research community. The biggest jump in exploits we see is right after the release of a Metasploit module, he said.
