The U.S. Treasury Department said the average amount of reported ransomware transactions per month in 2021 was $102.3 million, with REvil/Sodinokibi, Conti, DarkSide, Avaddon, and Phobos the most prevalent ransomware strains reported.
Seeking to stop the use of crypto currencies in the payment of ransomware demands, Treasury told members of the crypto community they are responsible for making sure they do not "directly or indirectly" help facilitate deals prohibited by U.S. sanctions. "Treasury is helping to stop ransomware attacks by making it difficult for criminals to profit from their crimes, but we need partners in the private sector to help prevent this illicit activity," Deputy Treasury Secretary Wally Adeyemo said in a statement.
Hackers use ransomware to take down systems that control everything from hospital billing to manufacturing. They stop only after receiving hefty payments, typically in cryptocurrency.
