A spokesperson for China's State Internet Information Office on Monday published the latest data of US cyber attack, saying that China is a solid defender of Internet security.

The US is the biggest attacker of China's Internet, the spokesperson said, adding that the US charges of hacking against five Chinese military officers on Monday are "groundless".

Latest data from China's National Computer network Emergency Response technical Team Coordination Center (CNCERT) showed that from March 19 to May 18, a total of 2,077 Trojan horse networks or botnet servers in the US directly controlled 1.18 million host computers in China.

The CNCERT found 135 host computers in the US carrying 563 phishing pages targeting Chinese websites that led to 14,000 phishing operations. In the same period, the center found 2,016 IP addresses in the US had implanted backdoors in 1,754 Chinese websites, involving 57,000 backdoor attacks.

The US attacks, infiltrates and taps Chinese networks belonging to governments, institutions, enterprises, universities and major communication backbone networks. Those activities target Chinese leaders, ordinary citizens and anyone with a mobile phone. In the meantime, the US repeatedly accuses China of spying and hacking.

China has repeatedly asked the US to stop, but it never makes any statement on its wiretaps, nor does it desist, not to mention make apology to the Chinese people.

After the Prism program leaked by Edward Snowden, the United States was accused by the whole world. However, it has never made retrospection, instead, it accuses others.

The spokesperson said the Chinese government opposes any kinds of Internet-related crimes, and any groundless accusations against the country.

If the United States goes its own way, China will take countermeasures, the spokesperson said.
