I work as an IT Security Consultant at T-Systems International GmbH / Telekom Security in Germany and I write about Security related topics.
The crackthe.net domain is not for sale. I've used this domain name since March 2010 as both my personal domain and originally for quite a few projects I was involved with. Even though most of those projects have spun off into different domains of their own now, I'm still pretty attached to crackthe.net as my personal domain.
