WASHINGTON, D.C. — The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC), in partnership with Australia’s Department of Foreign Affairs and Trade and the United Kingdom’s Foreign Commonwealth and Development Office, has imposed coordinated sanctions against Zservers, a Russian bulletproof hosting (BPH) services provider. This joint action underscores increasing international collaboration to dismantle cybercriminal networks and disrupt the activities that enable them.
Zservers has been linked to facilitating LockBit ransomware operations, one of the most prolific ransomware variants in circulation. By providing BPH services designed to evade law enforcement and cybersecurity defenses, Zservers has become a key enabler of these attacks. LockBit ransomware is responsible for numerous high-profile incidents, including the widespread disruption caused by the November 2023 attack on the Industrial Commercial Bank of China’s U.S. broker-dealer branch.
“Ransomware actors and other cybercriminals rely on third-party network service providers like Zservers to carry out their attacks on critical infrastructure in the United States and abroad,” stated Acting Under Secretary of the Treasury for Terrorism and Financial Intelligence Bradley T. Smith. “This trilateral action with our Australian and UK allies demonstrates our shared commitment to disrupting all layers of the ransomware ecosystem, wherever they operate, to protect national and global security.”
Zservers’ Role in Facilitating Cybercrime
Operating from Barnaul, Russia, Zservers has positioned itself as a provider of BPH services tailored to the needs of cybercriminals. BPH platforms specialize in leasing servers and internet protocol (IP) addresses that facilitate illicit online activities while avoiding detection. Zservers has actively advertised its services on cybercriminal forums, thereby catering to ransomware operators and other malicious networks.
A key example of Zservers’ complicity was uncovered in 2022. Canadian authorities, during a search of a LockBit affiliate, discovered a laptop linked to a Zservers-provided IP address. The laptop operated a LockBit malware interface, illustrating how Zservers’ infrastructure directly supported ransomware deployment. Further evidence in 2023 revealed that Zservers had leased critical hosting infrastructure to LockBit affiliates, solidifying its role in cybercrime operations.
Designation of Zservers and Associated Individuals
OFAC has designated Zservers under Executive Order 13694 (amended by E.O. 14144). This classification applies to entities that provide material support or services to cyber-enabled activities deemed to threaten U.S. national security, foreign policy, or economic stability.
The sanctions also extend to two Russian nationals, Alexander Igorevich Mishin and Aleksandr Sergeyevich Bolshakov, both of whom are linked to Zservers. Mishin has been identified as an administrator promoting Zservers’ services directly to cybercriminals, enabling ransomware operations through virtual currency transactions. Bolshakov worked with Mishin to mitigate law enforcement scrutiny. Notably, in 2023, the pair reallocated IP addresses used in LockBit attacks, attempting to deflect legal complaints while maintaining services for their criminal clients.
International Collaboration to Combat Ransomware
This joint designation is part of a broader collaborative effort to dismantle ransomware ecosystems globally. The action builds on previous sanctions imposed by the U.S., Australia, and the UK, such as those targeting Russian ransomware operator Alexander Ermakov and members of the Evil Corp group. The strategic alliance between these nations reflects a shared recognition of the threat ransomware poses to critical infrastructure and financial stability worldwide.
The investigation leading to these sanctions was conducted in coordination with the Department of Justice and the Federal Bureau of Investigation. The involvement of multiple agencies further highlights the complexity and scale of the global fight against cybercrime.
Implications of Sanctions
The sanctions imposed freeze all assets of Zservers, Mishin, and Bolshakov within U.S. jurisdiction and prohibit U.S. persons from engaging in transactions involving their property. Companies or individuals facilitating deals with these entities risk secondary sanctions. The action aims not only to disrupt ongoing cybercriminal operations but also to discourage infrastructure providers from supporting illegal activity.
OFAC reiterated that while sanctions are a critical tool for enforcement, their ultimate purpose is to incentivize behavioral change. Designated entities may be removed from sanctions lists if they demonstrate compliance with international norms.
Forward Look at Cybersecurity Challenges
This decisive action marks a significant step in weakening the infrastructure relied upon by ransomware actors. By targeting BPH providers and other service enablers, governments are addressing the broader ecosystem that allows cybercrime to thrive. Collaborative efforts like these are essential to reinforcing global cybersecurity measures and deterring criminal behavior.
Looking ahead, experts anticipate continued international collaboration to identify and dismantle networks supporting ransomware activities. Enhanced information sharing and coordinated actions will serve as pivotal strategies in addressing the evolving threat posed by sophisticated cybercriminal groups.
The designation of Zservers and its administrators sends a clear message that no element of the ransomware ecosystem is beyond the reach of law enforcement and sanctions. This action underscores a collective global commitment to ensuring the security of critical infrastructure and protecting victims against cyber extortion.
