Chinese computers account for 42% of malicious activity in the region, but also were the target of 74% of DOS attacks. (Sri Lanka generated the most malicious activity per user, followed by Bangladesh and Taiwan.)
The other emerging trend is the growth in multi-stage attacks. These typically begin with a benign, low-profile penetration from which subsequent attacks are launched - typically, taking the browser to a web page containing malicious code, or downloading a keystroke logger. Most of these attacks are aimed at gaining access to personal data for the purpose of financial fraud.
For the record, the Chinese attacks on western government networks, as claimed by the Pentagon, were multi-stage, taking place over several months.
As to whether that was the PLA, or Chinese gangs, or US gangs pretending to be Chinese, or US cyber-war fighters channeling the PLA, or the PLA sowing confusion by feigning to be foreigners trying to be the PLA, no one knows - possibly including the PLA.
Let's hope none of them has left their credit card details online.
