Blender, the cryptocurrency mixer sanctioned by the United States Department of the Treasury’s Office of Foreign Assets Control in May 2022, was “highly likely” relaunched as Sinbad, according to risk management firm Elliptic.

In a Feb. 13 report, Elliptic said its analysis of Sinbad suggested that the crypto mixer was likely a rebrand of Blender as well as having “the same individual or group responsible for it.” According to the firm, Sinbad was behind laundering roughly $100 million in Bitcoin (BTC) for North Korea’s hacking group Lazarus.

Elliptic said following U.S. authorities cracking down on crypto mixers — as OFAC did with Tornado Cash in August and Blender in May — Lazarus hackers used Sinbad to launder some of the funds from the $100-million attack on Horizon Bridge in January. Blockchain analysis of wallets tied to a suspected Blender operator also showed $22 million in crypto going to Sinbad and other funds sent to individuals who promoted the mixer.
