Penetration Tester/ Ethical Hacker
I hack stuff for fun and profit, at the moment at Siemens AG in Germany. I was also an external consultant for various companies in insurance, banking, telco or even car production. When I have some free time I also talk at conferences. I also have a Youtube channel where I regularly upload hacking videos.
Here at Udemy my goal is to put my knowledge and experience in a form which is useful for others, to save you the time, which I spent to acquire all this knowledge from different sources.
