A report by Symantec claims 30 percent of malicious e-mails were sent from China and that 21.3 percent came from the city of Shoaxing alone. Over 4.3 million people live in this prefecture-level city, which has the questionable honor of being named world's malware capital.
Symantec succeeded in tracing individual computer registration numbers, known as IPs, to find the true source of the attacks. Previously, hackers in China had been able to camouflage themselves behind servers in Taiwan.
The findings show China was the source of 28.2% of global targeted attacks. It was followed by Romania, with 21.1%, presumed to be mostly attempts at commercial fraud. The United States came third, followed by Taiwan and then Britain, with 12% of attacks.
