Blender Reborn? Sinbad Crypto Mixer Suspected in Lazarus Group’s Money Laundering

In the ever-evolving world of cryptocurrency, where innovation meets anonymity, a familiar name might be operating under a new guise. Remember Blender, the crypto mixer that supposedly shut down in April 2022? Well, buckle up, because a recent report suggests it might just be back, rebranded as “Sinbad,” and potentially still entangled with North Korea’s notorious Lazarus Group. Let’s dive into the details of this intriguing crypto mystery.

Blender’s Alleged Reincarnation: Meet Sinbad

According to a compelling study released on February 13th by the analytics firm Elliptic, the crypto mixer Blender, despite claims of ceasing operations, appears to have simply undergone a name change. Elliptic’s investigation points towards “Sinbad” as the likely successor, suggesting that the service remains active and potentially still favored by groups like the Lazarus Group, a North Korean state-sponsored hacking organization.

Elliptic’s findings are based on a meticulous analysis of on-chain transactions and operational patterns. They highlight several key pieces of evidence suggesting a strong link between Blender and Sinbad:

• Financial Footprints: Elliptic uncovered that the operator behind Blender made a substantial initial Bitcoin transfer of $22 million to Sinbad. This was followed by another payment to a “service” address, further strengthening the connection.
• Promoter Payments: Intriguingly, the Blender operator also deposited Bitcoin into a wallet that was used to pay Sinbad’s promoters. This shared financial trail adds another layer to the suspicion of rebranding.
• Behavioral and Website Parallels: By scrutinizing on-chain behavior, website features, and language support, Elliptic identified striking similarities between Sinbad and Blender. Both mixers seem to share connections to Russia, evident in their supported languages and website characteristics.

Lazarus Group’s Shadowy Embrace: Mixers in Cyber Attacks

The implications of Blender’s potential rebranding as Sinbad extend beyond mere corporate reshuffling. Elliptic’s report further alleges that both Blender and Sinbad have been tools of choice for the Lazarus Group in orchestrating and laundering proceeds from major cyberattacks. Let’s look at two prominent examples:

• The Ronin Bridge Heist (March 2022): In a brazen attack, Lazarus Group targeted Ronin Bridge, linked to the popular blockchain game Axie Infinity, making off with over $540 million. Following this massive theft, a staggering $475 million was laundered through various crypto mixers, with Blender identified as one of them.
• The Horizon Bridge Breach (June 2022): Just months later, Lazarus struck again, this time hitting the cross-chain bridge Horizon and seizing $100 million. Elliptic claims that Sinbad, which emerged online in October 2022, was subsequently used by Lazarus to launder approximately $100 million originating from the Horizon hack and other illicit sources.

Interestingly, Tornado Cash, another well-known crypto mixer, was also reportedly used in both the Ronin Bridge and Horizon Bridge attacks. Despite facing sanctions from the US Treasury’s Office of Foreign Assets Control (OFAC) in August 2022, Tornado Cash continues to operate. Elliptic suggests that Sinbad might face similar regulatory scrutiny, noting that addresses associated with both Blender and Sinbad are already flagged in their compliance services.

Why Mixers Matter: Privacy vs. Illicit Activities

Coin or crypto mixers, like Blender and Sinbad, are designed to obscure the origin and destination of cryptocurrency transactions. They essentially “mix” different cryptocurrencies together, making it harder to trace the flow of funds on the blockchain. While this technology can be used for legitimate purposes, such as enhancing privacy for individuals in crypto transactions, it also presents a significant risk.

Legitimate Uses of Crypto Mixers:

• Enhanced Privacy: For users seeking to keep their financial activities private, mixers can provide a layer of anonymity. This is particularly relevant in jurisdictions with surveillance concerns or for individuals who simply value financial privacy.
• Protecting Business Transactions: Businesses might use mixers to protect sensitive transaction details from competitors or public scrutiny.
• Donations to Sensitive Causes: Individuals donating to politically sensitive causes or organizations might use mixers to protect their identities and avoid potential repercussions.

The Dark Side: Challenges and Illicit Use:

• Money Laundering: As highlighted by the Lazarus Group case, mixers are frequently exploited for laundering illicit funds obtained from cybercrime, drug trafficking, and other illegal activities.
• Terrorist Financing: The anonymity offered by mixers can be misused to finance terrorist activities, making it difficult for authorities to track and prevent such funding.
• Regulatory Scrutiny: Due to their potential for illicit use, crypto mixers are increasingly facing regulatory pressure and sanctions from government agencies worldwide. This can lead to service disruptions and legal repercussions for users and operators.

The Road Ahead: Enforcement and the Future of Mixers

The Elliptic report serves as a stark reminder of the ongoing challenges in regulating the cryptocurrency space. While mixers can offer legitimate privacy solutions, their potential for misuse in money laundering and other illicit activities is undeniable. The case of Blender and Sinbad underscores the need for:

• Enhanced Regulatory Oversight: Governments and regulatory bodies need to develop more effective strategies to monitor and regulate crypto mixers to prevent their misuse without stifling legitimate innovation.
• Improved Blockchain Analytics: Companies like Elliptic play a crucial role in developing sophisticated tools to trace and analyze cryptocurrency transactions, helping to identify and disrupt illicit activities.
• International Cooperation: Cybercrime and money laundering are global issues requiring international cooperation among law enforcement agencies and regulatory bodies to effectively combat them.

Conclusion: A Crypto Cat and Mouse Game

The story of Blender and Sinbad highlights the cat-and-mouse game between those seeking to exploit the anonymity of cryptocurrency for illicit purposes and those striving to maintain a secure and compliant crypto ecosystem. As technology evolves, so do the methods of both criminals and law enforcement. The crypto community and regulators must remain vigilant, proactive, and collaborative to navigate the complex landscape of crypto mixers and ensure that innovation doesn’t come at the cost of security and legality. The rebranding saga of Blender to Sinbad serves as a critical case study in this ongoing balancing act.
