Does anyone have any ideas on where the worst Global Hackers Live (from a USA perspective). By this I mean, where do warez, serialz, botnets, spammers have their residence? In what countries are those hackers most likely to live? How do they connect to the internet? Is banning their home continent effective in curbing their access? (or do they use unknown proxies?)
I want to block likely hackers based on IP address / contient (i.e. China / Russia). I don’t care if I alienate a large group of users.
Also, any freely available blocklists for this purpose?
UPDATE: This is programming related because blacklisting is a common programming task. And programmers are one of the few groups that care about this type of data. Who else would I ask?
South America in General, but mostly Brazil
China and Korea
South Eastern Europe: Hungary, Czech, etc.
