A Moscow court on Saturday took three other alleged members of the REvil ransomware criminal group into custody for illegally smuggling funds, a day after Russia claimed it took down the group at the request of the United States.
The court identified the three men as Mikhail Golovachuk, Ruslan Khansvyarov and Dmitry Korotayev.

In a rare apparent show of US-Russian collaboration at a time of heightened tensions between the two over Ukraine, Russian authorities arrested and charged members of the REVil group this week.
A police and FSB domestic intelligence operation searched 25 addresses, detaining 14 people, the FSB said Friday, listing the assets it had seized, including $600,000 worth of computer equipment and 20 luxury cars.
The United States welcomed the arrests.
The United States said in November it was offering a reward of up to $10 million for information leading to the identification or location of anyone in a key position within the REvil group.
A source familiar with the matter told Interfax that members of the group with Russian nationality would not be handed over to the United States.
