China saw an increase in Trojan and botnet attacks coming from other countries in 2012, as the amount of mobile malware in the country also surged, according to a local security group.
During the year, a total of 73,000 Trojan and botnet command-and-control servers had hijacked 14.2 million host machines in the country. The number of Trojan and botnet servers marks an almost 60 percent increase from 2011.
Close to 13,000 of those servers were based in the U.S., the country also responsible for the largest number of Trojan and botnet attacks targeting China. South Korea was second, followed by Germany.
China's National Computer Network Emergency Response Technical Team (CNCERT) reported the figures on Thursday. They were later published by the nation's state press, Xinhua News Agency.
