In a widespread attack, ransomware hackers have demanded $70 million to unlock computers.
The cyberattack, which began on Friday, is thought to have affected hundreds of small and medium-sized enterprises as well as tens of thousands of devices.

The CEO of the company at the center of a massive hack that has impacted hundreds of businesses claimed he told the White House and that the perpetrators are demanding a single extortion payment of $70 million.
