Treasury Sanctions Mixer Used by the DPRK to Launder Stolen
Virtual Currency
November 29, 2023

Mixing services that enable cybercriminals continue to face consequences
WASHINGTON — Today, the U.S. Department of the Treasuryʼs O ice of Foreign Assets
Control (OFAC) sanctioned Sinbad.io (Sinbad), a virtual currency mixer that serves as a key
money-laundering tool of the OFAC-designated Lazarus Group, a state-sponsored cyber
hacking group of the Democratic Peopleʼs Republic of Korea (DPRK). Sinbad has processed
millions of dollarsʼ worth of virtual currency from Lazarus Group heists, including the Horizon
Bridge and Axie Infinity heists. Sinbad is also used by cybercriminals to obfuscate transactions
linked to malign activities such as sanctions evasion, drug tra icking, the purchase of child
sexual abuse materials, and additional illicit sales on darknet marketplaces.
“Mixing services that enable criminal actors, such as the Lazarus Group, to launder stolen
assets will face serious consequences,” said Deputy Secretary of the Treasury Wally Adeyemo.
“The Treasury Department and its U.S. government partners stand ready to deploy all tools at
their disposal to prevent virtual currency mixers, like Sinbad, from facilitating illicit activities.
While we encourage responsible innovation in the digital asset ecosystem, we will not
hesitate to take action against illicit actors.”
The Treasury Departmentʼs designation of Sinbad builds on earlier actions to expose elements
of the virtual currency ecosystem that malicious cyber actors, in particular the Lazarus Group,
use to obfuscate the origins and destinations of proceeds from their illicit activities. On May
6, 2022, OFAC sanctioned Blender.io, the first ever designation of a virtual currency mixer, and
on November 8, 2022, OFAC redesignated Tornado Cash, both of which provided mixing
services to the Lazarus Group. On April 24, 2023, OFAC sanctioned two over-the-counter
virtual currency traders who facilitated the conversion of stolen virtual currency to fiat
currency for DPRK actors working with the Lazarus Group.

Sinbad is responsible for materially assisting in the laundering of millions of dollars in stolen
virtual currency and is a preferred mixing service for the Lazarus Group. Sinbad operates on
the Bitcoin blockchain and indiscriminately facilitates illicit transactions by obfuscating their
origin, destination, and counterparties. Sinbad is believed by some industry experts to be a
successor to the Blender.io mixer, which OFAC designated for providing mixing services to the
Lazarus Group.
Sinbad was used to launder a significant portion of the $100 million worth of virtual currency
stolen on June 3, 2023, from customers of Atomic Wallet. Sinbad was also used to launder a
significant portion of virtual currency from the Axie Infinity heist of approximately $620 million
in March 2022, and the Horizon Bridge heist of approximately $100 million in June 2022.
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. The Lazarus Group has operated for more than ten years and is
believed to have stolen over $2 billion worth of digital assets across multiple the s. Due to
the pressure of robust U.S. and United Nations sanctions, the DPRK has resorted to using
illicit tactics, such as heists perpetrated by the Lazarus Group, to generate revenue for its
unlawful weapons of mass destruction and ballistic missile programs.
Sinbad is being designated pursuant to E.O. 13694, as amended by E.O. 13757,
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, and pursuant to E.O. 13722 for
having materially assisted, sponsored, or provided financial, material, or technological support
for, or goods or services to or in support of, the Government of the DPRK, a person whose
property and interests in property are blocked pursuant to E.O. 13722.

blocked and reported to OFAC. OFACʼs regulations generally prohibit all dealings by U.S.
persons or within the United States (including transactions transiting the United States) that
involve any property or interests in property of a blocked or designated entity.
In addition, persons that engage in certain transactions with the entity designated today may
themselves be exposed to sanctions.
The power and integrity of sanctions derive not only from OFACʼs ability to designate and add
persons to the Specially Designated Nationals and Blocked Persons (SDN) List but also from
its willingness to remove persons from the SDN List consistent with the law. The ultimate
goal of sanctions is not to punish but to bring about a positive change in behavior. For
information concerning the process for seeking removal from an OFAC list, including the SDN
List, please refer to OFACʼs Frequently Asked Question 897 here. For detailed information on
the process to submit a request for removal from an OFAC sanctions list, please click here.
