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.
Most online attacks were Trojan viruses and bots.
There were more than 17 million cyberattacks in both 2015 and 2016, and "it can be clearly seen that our security situation is still weak," said Li Jia, deputy director of the authority's operations department.
He added that attacks on China's critical infrastructure and key data have never stopped.
"If the intrusions are successful, the damage to our State security will be huge - beyond our imagination," he said.
To alleviate such security problems, the authority shares information about security risks on its official social media platforms and website in a timely manner.
