From the Times of India:
The firm traced 12 billion emails in a study which showed that a higher number of “targeted attacks” on computers come from China than previously thought. Researchers for Symantec found almost 30 of “malicious” emails were sent from China and that 21.3 came from the city of Shaoxing alone. They were able to identify key targets for the hackers as experts in Asian defence policy and human rights activists, strongly suggesting state involvement.
Symantec is assisting the probe into suspected hacking attacks on Google, which closed its website in China last week. Symantec succeeded in tracing computer registration numbers, known as IPs, to find true source of the attacks. Previously, hackers in China had been camouflaging behind Taiwan servers.
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 UK, with 12 of attacks.
