Chinese local authorities from traffic police to industry regulators were hobbled on Monday by a massive global ransomware attack, but the spread of the WannaCry worm in the country appeared less aggressive than initially feared. Dozens of local Chinese authorities said they had suspended some of their services due to the attack that has disrupted operations at car factories, hospitals, shops and schools around the world. "The growth rate of infected institutions on Monday has slowed significantly compared to the previous two days," said Chinese Internet security company Qihoo 360.
