WannaCry hackings expose weaknesses

The recent widespread ransomware cyberattack is a landmark incident showing that computer viruses can attack anyone anywhere rather than just targeting certain groups, senior Chinese cybersecurity officials said.

They also said China must be able to handle similar and even worse attacks in the future.

"WannaCry has no specific target. All Windows users are potentially the targets of the highly infectious virus. It has caused enormous panic among people around the world because it poses a direct threat," said Liu Xinran, deputy director of the National Computer Network Emergency Response Technical Coordination Center.
