US main source of cyberattacks against China

China was subject to an increasing number of cyberattacks in the first two months of this year, with more than half launched from the United States, China's Internet security watchdog said.

In the past two months, 6,747 overseas servers were found to use Trojans or botnets to control nearly 1.9 million mainframes in China. Among them, 2,194 servers located in the United States had controlled 1.287 million mainframes, making it the largest point of origin of cyberattacks against China, the National Computer Network Emergency Response Coordination Center said on Sunday.

More than 11,000 Chinese websites were hacked by 5,324 mainframe computers from overseas in January and February using the backdoor method, with more than 3,500 websites hacked by 1,959 mainframe computers in the United States. Some 132 mainframe computers located in Japan controlled 473 websites.
