Sneak attacks come from United States

The most aggressive attacks on Chinese cyberspace originate from within the United States, and the US is the biggest thief of secrets in the world, Xinhua News Agency quoted a representative of China's State Internet Information Office as saying.

From March 19 to May 18, 2,077 Trojan-horse networks or "botnet" servers originating in the US controlled 1.18 million computers in China, according to the country's network emergency response center.

Meanwhile, 135 computers from inside the US controlled 563 phishing websites targeting China, leading to 14,000 cases of online fraud, such as theft of users' personal information, online passwords and locations, the center said.
