The unprecedented global cyberattack affected "more than 75,000 victims" in dozens of countries, French police said in a statement Saturday, the day after the ransomware hit Russia's banks, British hospitals and European car factories among others.

"This is a provisional figure of the number of infected computers and could rise significantly over the coming days," Valerie Maldonado, deputy head of the French police's anti-Cybercrime Office told AFP.
