We have online revolutionaries anarchists and REAL nation-wide revolutions, started on online networks (talking about Arabic Spring here); we got FBI agents, looking through IP addresses on IRC networks to catch a small group of bragging attackers; we got invisible army of Chinese hackers that noone knows who they are, only that they are really good; some unknown entity making amazingly well done and thought out trojan like stuxnet and now duqu, that seems to be right from pages of some hyperbolic comic book; and, last but not the least, the Russian mafia lords employing Zeus trojans and whatnot to make botnets that mine bitcoin, purely digital currency.
It's an amazing world we live in. Can't wait what the future will bring.
