While it's true.....
China is the source of lots of hacking / botnet / intrusion, per capita it's actually not as bad as the US (per capita), probably due to the rather split demographic in China, pretty much 50/50 with those who have access to IT and those that don't.
To be fair, China is also one of the best sources for open proxies... apparently, which would definitely skew the "original source", not that I'd know obviously, after all I can't imagine what use a proxy in another country would be.... ahem.
