Some United States senators are ramping up the anti-crypto rhetoric again, urging federal agencies to take action against the illicit use of digital assets. Senator Maggie Hassan is the latest to raise concerns about the use of cryptocurrency as a means of payment for ransomware attacks. The Senate Homeland Security and Governmental Affairs Committee member sent a letter on Thursday to several agencies, including the Justice Department, the Department of Homeland Security, the Internal Revenue Service, the Securities and Exchange Commission, and the Treasury Department’s Financial Crimes Enforcement Network.
