Microsoft used a federal court order to try to cut off cybercriminals’ access to a hacking tool that has been used in nearly 70 ransomware attacks on health organizations in more than 19 countries, the tech giant said Thursday.

As the coronavirus pandemic strained health care systems around the US, cybercriminals continued to opportunistically lock up the computer networks of hospitals and demand a ransom.

Weiss told CNN that he believes many hospitals are quietly paying ransoms to hackers because the hospitals “are supporting life-critical functions and they have to get back into operation as soon as possible.”
