My Name is Peter Vreugdenhil. Im a freelance vulnerability researcher from Holland. Besides that I also work as an internet developer for a company that mainly makes webshop for big companies. My job there involves a lot of Perl programming which is also one of the main languages I use to write some of my fuzzers. I wrote fuzzers for ActiveX (I’ll post about that later), file fuzzers, browser fuzzers and combinations of those.
Most of the vulnerabilities I found came from the fuzzers I wrote although recently I have been using reverse enginering as a way to find vulnerabilities.
