Aspect Security

Arshan Dabirsiaghi is the Director of Research at Aspect Security, a company that specializes in a range of application security services. He's found vulnerabilities in big, popular software, discovered new attack techniques, spoken at big conferences, and blah, blah, blah.

Really, he just left PR hack on AOL yesterday and spends most of his research time finding bugs that Sami Koivu found months or years ago.
