Hello Everyone, My name is Rassoul Ghaznavi-Zadeh and I am an author, teacher and security expert. I have a couple of books including Ethical hacking with Kali Linux, Application hacking and security architecture. You can Google my name to find more about me or visit my personal website which is rassoul.info. I used to be a long member of blackhat before all the changes, and then for awhile I was off working on other thing. Now I am back and hoping to use the great extensive resources available here.
