  • Is an IDS any good, or how skilled is your Red Team?
Martin Haunschmid

Martin was a long-time developer, before one of his websites got hacked. This way, he realized you can earn money (officially, of course, and always with a permission to attack) doing something he now considers the best job there is. Nowadays he's mostly doing Application Security in the form of black-box web-app penetration tests and source code reviews via his company Adversary GmbH.

Other than that, he tries to communicate his fascination with the industry to not-so-technical folk by producing the "Hacks of the Week" and sometimes does talks.
