U.S. Treasury Issues First-Ever Sanctions on a Virtual Currency
Mixer, Targets DPRK Cyber Threats
May 6, 2022

Additional Lazarus Group Virtual Wallet Addresses Identified
WASHINGTON – Today, the U.S. Department of the Treasuryʼs O ice of Foreign Assets Control
(OFAC) sanctioned virtual currency mixer Blender.io (Blender), which is used by the Democratic
Peopleʼs Republic of Korea (DPRK) to support its malicious cyber activities and moneylaundering of stolen virtual currency. On March 23, 2022, Lazarus Group, a DPRK statesponsored cyber hacking group, carried out the largest virtual currency heist to date, worth
almost $620 million, from a blockchain project linked to the online game Axie Infinity; Blender
was used in processing over $20.5 million of the illicit proceeds. Under the pressure of robust
U.S. and UN sanctions, the DPRK has resorted to illicit activities, including cyber-enabled
heists from cryptocurrency exchanges and financial institutions, to generate revenue for its
unlawful weapons of mass destruction (WMD) and ballistic missile programs.
“Today, for the first time ever, Treasury is sanctioning a virtual currency mixer,” said Under
Secretary of the Treasury for Terrorism and Financial Intelligence Brian E. Nelson. “Virtual
currency mixers that assist illicit transactions pose a threat to U.S. national security interests.
We are taking action against illicit financial activity by the DPRK and will not allow statesponsored thievery and its money-laundering enablers to go unanswered.”
Treasury is also updating the List of Specially Designated Nationals and Blocked Persons (SDN
List) to identify additional virtual currency addresses used by the Lazarus Group to launder
illicit proceeds. Treasury is committed to exposing components of the virtual currency
ecosystem, like Blender, that are critical to the obfuscation of the trail of stolen proceeds
from illicit cyber activity. OFAC sanctioned the Lazarus Group on September 13, 2019, pursuant
to Executive Order (E.O.) 13722, and identified it as an agency, instrumentality, or controlled
entity of the Government of the DPRK, based on its relationship to the U.S.- and UNdesignated Reconnaissance General Bureau, the DPRKʼs premiere intelligence organization,
which is also involved in conventional arms trade.

T REASURY DESIGNAT ES F IRST MIXER

Blender.io (Blender) is a virtual currency mixer that operates on the Bitcoin blockchain and
indiscriminately facilitates illicit transactions by obfuscating their origin, destination, and
counterparties. Blender receives a variety of transactions and mixes them together before
transmitting them to their ultimate destinations. While the purported purpose is to increase
privacy, mixers like Blender are commonly used by illicit actors. Blender has helped transfer
more than $500 million worth of Bitcoin since its creation in 2017. Blender was used in the
laundering process for DPRKʼs Axie Infinity heist, processing over $20.5 million in illicit
proceeds.
OFACʼs investigation also identified Blenderʼs facilitation of money-laundering for, among
others, Russian-linked malign ransomware groups including Trickbot, Conti, Ryuk, Sodinokibi,
and Gandcrab.

Blender 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 e ect 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.
While most virtual currency activity is licit, it can be used for illicit activity, including sanctions
evasion, through mixers, peer-to-peer exchangers, darknet markets, and exchanges. This
includes the facilitation of heists, ransomware schemes, and other cybercrimes. Treasury
continues to use its authorities against malicious cyber actors in concert with other U.S.
departments and agencies, as well as our foreign partners, to disrupt financial nodes tied to
illicit payments and cyber-attacks. Those in the virtual currency industry play a critical role in
implementing appropriate Anti-Money Laundering /Countering the Financing of Terrorism
(AML/CFT) and sanctions controls to prevent sanctioned persons and other illicit actors from
exploiting virtual currency to undermine U.S foreign policy and national security interests.
The virtual currency mixers that assist criminals are a threat to U.S. national security interests.
Treasury will continue to investigate the use of mixers for illicit purposes and consider the
range of authorities Treasury has to respond to illicit financing risks in the virtual currency
ecosystem. For example, in 2020, Treasuryʼs Financial Crime Enforcement Network (FinCEN)
assessed a $60 million civil money penalty

against the owner and operator of a virtual

currency mixer for violations of the Bank Secrecy Act (BSA) and its implementing regulations.
Criminals have increased use of anonymity-enhancing technologies, including mixers, to help
hide the movement or origin of funds. Additional information on illicit financing risks
associated with mixers and other anonymity-enhancing technologies in the virtual asset
ecosystem can be found in the 2022 National Money Laundering Risk Assessment

.

ADDIT IONAL LAZARUS GROUP W ALLET
OFAC is identifying four additional virtual currency wallet addresses used by the Lazarus
Group to launder the remainder of stolen proceeds from the March 2022 Axie Infinity heist.
This builds upon OFACʼs April 14, 2022, attribution of DPRKʼs Lazarus Group as the
perpetrators of the Axie Infinity heist and identification of the original getaway wallet
address. Treasury is committed to tracing illicit virtual currency and blocking associated
wallets and addresses wherever found.
