In a significant and coordinated international effort, U.S. law enforcement, in conjunction with partners from around the world, has announced a major takedown of the BlackSuit (Royal) ransomware group. The operation, which took place on July 24, 2025, involved the seizure of four servers and nine domains used by the group to conduct their malicious activities. This action represents a critical step in dismantling the infrastructure of a cybercriminal organization that has targeted numerous critical infrastructure sectors in the U.S., including healthcare, government facilities, and critical manufacturing.
The takedown was a collaborative effort involving several key U.S. agencies, including the Department of Homeland Security’s Homeland Security Investigations (HSI), the U.S. Secret Service, the FBI, and IRS Criminal Investigation (IRS-CI). These domestic efforts were bolstered by the cooperation of international partners from the United Kingdom, Germany, Ireland, France, Canada, Ukraine, and Lithuania. This global coordination highlights the seriousness with which governments are treating the threat of ransomware and the necessity of a unified front to combat it.
A central component of this operation was the seizure of approximately $1.1 million in laundered cryptocurrency. The unsealing of a warrant for this virtual currency seizure, announced by the U.S. Attorney’s Offices for the Eastern District of Virginia and the District of Columbia, directly impacts the group’s financial resources. The seized funds were part of a ransom payment from a victim who paid 49.3120227 Bitcoin in April 2023. These proceeds were traced through a virtual currency exchange until they were frozen in January 2024, demonstrating the investigative capabilities of law enforcement to follow the money trail in cyberspace.
The announcement included strong statements from various officials, underscoring the commitment to a “disruption-first approach” against cyber threats. Assistant Attorney General for National Security John A. Eisenberg emphasized the serious threat BlackSuit poses to U.S. public safety and critical infrastructure. U.S. Attorneys Erik S. Siebert and Jeanine Ferris Pirro reinforced the resolve of their offices to protect businesses and hold criminals accountable. This concerted effort is not just about taking down servers but about “dismantling the entire ecosystem that enables cybercriminals to operate with impunity,” as stated by Deputy Assistant Director Michael Prado of HSI’s Cyber Crimes Center.
This successful operation against the BlackSuit ransomware group serves as a powerful message to cybercriminals worldwide. It showcases the growing capacity of law enforcement to work across international borders to investigate and disrupt sophisticated cyberattacks. By targeting both the technical infrastructure and the financial networks of these groups, authorities are making it increasingly difficult for them to operate. The ongoing investigations by multiple agencies and international partners promise to continue the pressure on the BlackSuit group and other ransomware actors, ultimately making the digital world safer for businesses and individuals alike.
