Cybersecurity threat could cause damage 'beyond imagination'

Cybersecurity remains a major problem for China as electronic attacks are frequent worldwide and with no end in sight, according to a leading specialist on internet security.

From January to October, China was hit by about 17.5 million cyberattacks, most of them from overseas, according to the National Computer Network Emergency Response Technical Team and Coordination Center, the country's top security risk-monitoring authority.

Most online attacks were Trojan viruses and bots, which accounted for more than 17.23 million attacks. Most were from the United States, the authority said.
