Hangzhou data summit to focus on cyberattacks

The first data security summit will be held in Hangzhou, Zhejiang province, on Saturday. It will focus on the challenges posed by hackers such as last month's WannaCry ransomware attack, when criminals targeted computers running the Microsoft Windows operating system in 150 countries. In China, universities and energy companies were affected by the attack, regulators said.
