Someone who is a security expert should have know the orgin of the most used tools..
Go back to the original thread, he didn't even identify "nmap", he went way out on a limb claiming a Russian Hacker created some tool used the DoD, the obvious purpose so he could defend the Russian hackers in that thread, when in fact it was an American. He's too low for words to describe, a Russian hacker loving sellout is a start.
I call BS on that. I do project management but I don't know who was the pioneer in that field. Does that mean I don't know project management or can't be considered an expert?
I also do a lot of programming I know what/who Ada is but does that make me an expert programmer? although I don't know who created fortran.
