In a significant blow to cybercriminal activities, authorities have seized cryptocurrency assets amounting to over $1 million linked to the notorious BlackSuit ransomware group, previously known as Royal. This operation, named Operation Checkmate, was executed on July 24, involving collaborative efforts from the United States and several international law enforcement agencies including the UK’s National Crime Agency (NCA), and cyber units from Canada, France, Germany, Ireland, Lithuania, and Ukraine.
This successful takedown saw the permanent removal of four servers and nine domains associated with the BlackSuit gang. Recently unsealed warrants revealed that the US Department of Justice (DoJ) had placed a hold on crypto assets valued at approximately $1.09 million, seized earlier this year during the operation.
The funds in question were connected to a ransom payment made around April 4, 2023, when a victim paid 49.31 bitcoin, initially valued at about $1.45 million, to BlackSuit in exchange for data decryption. The cryptocurrency underwent various transactions, being repeatedly deposited and withdrawn before a virtual currency exchange froze the assets in January 2024.
Michael Prado, deputy assistant director of the Cyber Crimes Center at Homeland Security Investigations (HSI), emphasized the significance of this operation: “Disrupting ransomware infrastructure is not only about taking down servers – it’s about dismantling the entire ecosystem that enables cyber criminals to operate with impunity.”
Christopher Heck, acting special agent in charge at HSI Washington DC, articulated the broader commitment of the agency, stating, “This investigation reflects the full reach of HSI’s cyber mission and our commitment to protecting victims – whether they’re small businesses, school systems, or hospitals. We will continue to target the infrastructure, finances and operators behind these ransomware groups to ensure they have nowhere left to hide.”

In conjunction with HSI’s efforts, Paul Foster, deputy director of the NCA’s National Cyber Crime Unit, highlighted the global threat posed by ransomware, declaring, “Ransomware is the most damaging cyber crime threat globally and the BlackSuit strain has impacted victims in the UK and overseas.” He stressed the collaborative intelligence-sharing that was key to disrupting the group and encouraged potential victims to report incidents to authorities.
BlackSuit, which became recognizable in 2022, is believed to have connections with the infamous Conti gang and emerged as a significant player in the ransomware landscape. Initially operating under various aliases, it notably rebranded as BlackSuit after a major attack on the City of Dallas, Texas, in spring 2023.
This attack allowed the group to infiltrate city systems through a compromised account, leading to the theft of over a terabyte of sensitive files over a period of four weeks, ultimately culminating in the deployment of their ransomware.

Despite employing a conventional double encryption model, BlackSuit gained notoriety for its unique methods, including partial encryption strategies. Throughout its operational history, the group targeted a wide array of sectors, affecting nearly 500 victims in the United States and extorting upwards of $370 million.
Authorities continue to monitor and disrupt ransomware operations actively, and the implications of Operation Checkmate serve as a reminder of the international commitment to combatting cyber threats. The cooperation displayed among nations and law enforcement agencies signifies a united front against the evolving landscape of cybercrime, with law enforcement agencies urging potential victims for vigilance in protecting their systems.
As cyber threats are expected to adapt and become increasingly sophisticated, ongoing efforts will be crucial in mitigating risks posed by ransomware. The collaboration seen in this operation provides a beacon of hope in the fight against cybercrime, as agencies resolve to hold offenders accountable and protect vulnerable networks.
