Don't know if it's the gummint or a bunch of script kiddies with new computers but the Unix guys have been muttering under their breath about the Chinese hits for a couple of months now.
Oh, and hang a few spammers. Because we can.
I dunno - cut off the CN and RU domains and clean up the botnets and an awful lot of your problems go away.
Yep, the ISPs should beginning chopping off people's Internet connection the minute their computer is taken over and used in a botnet of some kind. And then to get back on their Internet connection again, the person who owns the PC has to prove that they've cleaned it up on their machine.
That's what needs to be done... :-)
