Today, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned virtual currency mixer Tornado Cash, which has been used to launder more than $7 billion worth of virtual currency since its creation in 2019. This includes over $455 million stolen by the Lazarus Group, a Democratic People’s Republic of Korea (DPRK) state-sponsored hacking group that was sanctioned by the U.S. in 2019, in the largest known virtual currency heist to date. Tornado Cash was subsequently used to launder more than $96 million of malicious cyber actors’ funds derived from the June 24, 2022 Harmony Bridge Heist, and at least $7.8 million from the August 2, 2022 Nomad Heist. Today’s action is being taken pursuant to Executive Order (E.O.) 13694, as amended, and follows OFAC’s May 6, 2022 designation of virtual currency mixer Blender.io (Blender). Treasury has worked to expose components of the virtual currency ecosystem, like Tornado Cash and Blender.io, that cybercriminals use to obfuscate the proceeds from illicit cyber activity and other crimes.Tornado Cash (Tornado) is a virtual currency mixer that operates on the Ethereum blockchain and indiscriminately facilitates anonymous transactions by obfuscating their origin, destination, and counterparties, with no attempt to determine their origin. Tornado receives a variety of transactions and mixes them together before transmitting them to their individual recipients. While the purported purpose is to increase privacy, mixers like Tornado are commonly used by illicit actors to launder funds, especially those stolen during significant heists.
Tornado is being designated pursuant to E.O. 13694, as amended, for having materially assisted, sponsored, or provided financial, material, or technological support for, or goods or services to or in support of, a cyber-enabled activity originating from, or directed by persons located, in whole or in substantial part, outside the United States that is reasonably likely to result in, or has materially contributed to, a significant threat to the national security, foreign policy, or economic health or financial stability of the United States and that has the purpose or effect of causing a significant misappropriation of funds or economic resources, trade secrets, personal identifiers, or financial information for commercial or competitive advantage or private financial gain. As a result of today’s action, all property and interests in property of the entity above, Tornado Cash, that is in the United States or in the possession or control of U.S. persons is blocked and must be reported to OFAC.
Executive Order 13694 Blocking the Property of Certain Persons Engaging in Significant Malicious Cyber-Enabled Activities;
Executive Order 13757 Taking Additional Steps to Address the National Emergency With Respect to Significant Malicious Cyber-Enabled Activities
On December 31, 2015, OFAC issued the Cyber-Related Sanctions Regulations, 31 CFR part 578 (80 FR 81752, December 31, 2015) (the “Regulations”) to implement Executive Order (E.O.) 13694 of April 1, 2015, “Blocking the Property of Certain Persons Engaging in Significant Malicious Cyber-Enabled Activities” (80 FR 18077, April 2, 2015), pursuant to authorities delegated to the Secretary of the Treasury in E.O. 13694. The Regulations were initially issued in abbreviated form for the purpose of providing immediate guidance to the public. OFAC is revising the Regulations to further implement E.O. 13694, as amended by E.O. 13757 of December 28, 2016, “Taking Additional Steps to Address the National Emergency With Respect to Significant Malicious Cyber-Enabled Activities” (82 FR 1, January 3, 2017), as well as certain provisions of title II of the Countering America's Adversaries Through Sanctions Act (Pub. L. 115–44, 131 Stat. 886 (codified in scattered sections of 22 U.S.C.)) (CAATSA). OFAC is amending and reissuing the Regulations as a more comprehensive set of regulations that includes additional interpretive guidance and definitions, general licenses, and other regulatory provisions that will provide further guidance to the public. Due to the number of regulatory sections being updated or added, OFAC is reissuing the Regulations in their entirety.
E.O. 13694, as Amended by E.O. 13757. On April 1, 2015, the President, invoking the authority of, inter alia, the International Emergency Economic Powers Act (50 U.S.C. 1701 et seq.) (IEEPA), issued E.O. 13694. In E.O. 13694, the President determined that the increasing prevalence and severity of malicious cyber-enabled activities originating from, or directed by persons located, in whole or in substantial part, outside the United States constitute an unusual and extraordinary threat to the national security, foreign policy, and economy of the United States, and declared a national emergency to deal with that threat.
On December 28, 2016, the President issued E.O. 13757 to take additional steps to deal with the national emergency with respect to significant malicious cyber-enabled activities declared in E.O. 13694. E.O. 13757 added an Annex to E.O. 13694 and amended section 1 of E.O. 13694 by replacing section 1(a) in its entirety.
