The FBI has seized the computer infrastructure used by a notorious ransomware gang which has extorted more than $100 million from hospitals, schools and other victims around the world, US officials announced Thursday.

FBI officials since July have had extraordinary access to the so-called Hive ransomware group's computer networks, FBI Director Christopher Wray said at a news conference, allowing the bureau to pass computer "keys" to victims so that they could decrypt their systems and thwart $130 million in ransom payments.

The hospital attacks during COVID were particularly heinous.
