WASHINGTON—The volume of suspected ransomware payments flagged by U.S. banks has surged this year, on pace to nearly double last year’s, the Treasury Department said Friday, highlighting the scale of a problem that governments across the world have described as a critical national security threat.
Nearly $600 million in transactions were linked to possible ransomware payments in so-called Suspicious Activity Reports financial services firms filed to the U.S. government in the first six months of this year, according to a Treasury Department report. That is more than 40% more than the total for all of 2020.
