In a major global operation targeting LockBit ransomware, four individuals have been arrested, critical infrastructure has been seized, and a series of financial sanctions have been imposed on key affiliates. This coordinated effort, involving law enforcement agencies from 12 countries, strikes a significant blow against one of the world’s most notorious ransomware groups, known for its widespread cyberattacks across critical industries.
What is LockBit Ransomware?
LockBit ransomware is a highly disruptive cyber threat that has dominated global ransomware attacks between 2021 and 2023. Operating on a Ransomware-as-a-Service (RaaS) model, LockBit’s core developers provide the ransomware tool to affiliates, who execute the actual attacks. In return, affiliates share a portion of their illicit earnings with the core group.
The LockBit ransomware group has targeted industries ranging from healthcare, education, and manufacturing, to critical services like energy and government agencies. Their strategy involves encrypting sensitive data and demanding ransom for its release, often threatening to expose stolen information if payments are not made.
The Multinational Crackdown: Operation Cronos
In a decisive response, law enforcement agencies from France, the United Kingdom, and Spain—with the support of Europol and Eurojust—executed Operation Cronos. This ongoing international effort aims to dismantle LockBit ransomware at every level, from its core developers to the affiliates responsible for executing attacks.
Arrests and Seizures
The recent phase of Operation Cronos led to four arrests and significant infrastructure seizures:
- In France, authorities arrested a suspected developer of LockBit ransomware.
- In the United Kingdom, two individuals were arrested for supporting LockBit affiliates.
- In Spain, police arrested the administrator of a Bulletproof hosting service used by LockBit to host stolen data and evade law enforcement detection.
Additionally, nine critical servers used by the LockBit ransomware group were seized in Spain. These servers formed part of the group’s infrastructure, facilitating the deployment of ransomware and hosting data stolen from victims.

Financial Sanctions Against LockBit Affiliates
In parallel with the arrests, Australia, the United Kingdom, and the United States imposed financial sanctions against individuals linked to LockBit ransomware and Evil Corp, another prominent cybercriminal group. While LockBit had previously denied any connection with Evil Corp, authorities identified a strong link between the two groups through their affiliates.
The sanctions targeted 15 Russian citizens identified as key players in these ransomware operations, freezing their assets and limiting their access to financial systems. These sanctions are part of a broader strategy to disrupt the financial networks that cybercriminals rely on to fund their operations.
Disrupting LockBit Ransomware’s Global Operations
The actions against LockBit ransomware are part of a sustained effort to dismantle its extensive global operations. Earlier phases of Operation Cronos had already dealt significant blows to LockBit’s infrastructure, including the February 2024 takedown of critical systems used by the group.
However, LockBit ransomware remains a formidable threat due to its decentralized model, which allows a large network of affiliates to continue operating even after key leaders are arrested. This wide distribution of actors results in variation in tactics and techniques used in attacks, making the group’s operations both widespread and adaptable.
No More Ransom: Support for Ransomware Victims
To mitigate the impact of LockBit ransomware and similar groups, law enforcement and cybersecurity professionals have developed decryption tools to help victims recover their files without paying a ransom. These tools are made available through the No More Ransom initiative, a collaboration between Europol, the FBI, and cybersecurity organizations.
The No More Ransom website offers free decryption solutions for more than 150 different ransomware types and is available in 37 languages. To date, more than 6 million victims worldwide have been able to recover their files without paying a ransom, thanks to this initiative.
Europol’s Role in Targeting LockBit Ransomware
Throughout this multinational crackdown, Europol played a central role in coordinating the operation. Europol provided vital support by facilitating information sharing between countries, offering technical and forensic expertise, and deploying experts to support national law enforcement agencies during critical action days.
One key aspect of the operation was cryptocurrency tracing, a technique used to track ransom payments made to LockBit ransomware operators. Europol’s advanced cryptocurrency tracing capabilities enabled authorities to identify several key actors involved in LockBit’s operations.
In addition, the Joint Cybercrime Action Taskforce (J-CAT), a standing team of cybercrime experts from multiple countries, worked together to ensure that law enforcement efforts were synchronized and effective.
The latest actions against LockBit ransomware, including arrests, infrastructure seizures, and financial sanctions, represent a significant step in the global fight against ransomware. By disrupting both the technical infrastructure and financial networks that support these operations, international law enforcement agencies are making it increasingly difficult for LockBit ransomware to operate.
With continued international cooperation and ongoing initiatives like No More Ransom, there is renewed hope that victims of ransomware can recover without paying ransom, and that groups like LockBit ransomware will eventually be eradicated.
