NY Times today:
"WASHINGTON — Three months after hackers working for a cyberunit of China’s People’s Liberation Army went silent amid evidence that they had stolen data from scores of American companies and government agencies, they appear to have resumed their attacks using different techniques, according to computer industry security experts and American officials....The hackers were behind scores of thefts of intellectual property and government documents over the past five years, according to a report by Mandiant in February that was confirmed by American officials. They have stolen product blueprints, manufacturing plans, clinical trial results, pricing documents, negotiation strategies and other proprietary information from more than 100 of Mandiant’s clients, predominantly in the United States.

I think this is one of the world's greatest threats. I've seen it firsthand. A couple of months ago, I was browsing my router's log and spotted several blocked attempted intrusions. Out of curiosity, I did an IP trace on one of them and it pointed to a city somewhere in China. It suggested to me that they were systematically testing every IP address out there for access. Something to be concerned about.
