On July 1, 2025, the U.S. Department of the Treasury imposed sanctions on Aeza Group LLC, a multinational hosting provider based in Russia, for supporting large-scale cybercrime activities.
MAIN CONTENT
The U.S. Department of the Treasury sanctions Aeza Group and its international affiliates for providing detection-resistant hosting services to cybercriminals.
A TRON cryptocurrency address related to the payment infrastructure of Aeza has been designated and is under close monitoring for illegal transactions.
The sanctions strategy focuses on the infrastructure of services supporting cybercrime rather than pursuing each individual after an incident.
Why did the U.S. Department of the Treasury sanction Aeza Group for cybercrime activities?
Mr. Andrea M. Gacki, Director of the Office of Foreign Assets Control (OFAC), emphasized targeting Aeza Group to cut off the infrastructure supporting ransomware attacks and global data theft.
On July 1, 2025, Aeza Group LLC and its leaders were sanctioned by the U.S. Department of the Treasury for providing bulletproof hosting services for cybercriminal groups. This system includes Aeza International Ltd. in the UK and its affiliates, reflecting cross-border coordination in managing high-risk infrastructure. According to Chainalysis, this is a continuation of pressure campaigns after OFAC previously sanctioned ZServers in February 2025, aiming to disrupt the support platform for cybercrime.
The sanctions against Aeza focus on critical infrastructure choke points, hindering the ability of cybercriminals to maintain operations through sustainable, hard-to-detect hosting services.

Which cryptocurrency addresses related to Aeza Group have been flagged?
The TRON address TU4tDFRvcKhAZ1jdihojmBWZqvJhQCnJ4F has been confirmed by OFAC as the payment connection point for Aeza Group for illegal services.
On-chain analysis from Chainalysis indicates that this address manages funds obtained through multiple intermediary entities to conceal the source of payments from clients. This wallet has received over $350,000 in cryptocurrency and has withdrawn funds through various exchanges. The payment supply chain has been expanded with deposit addresses connected to both escrow service providers, gaming platforms, and the Garantex exchange.
Notably, Aeza also has close ties with a darknet vendor specializing in selling information-stealing malware, with clients regularly paying the hosting fees set by Aeza, indicating a direct relationship with major cybercriminal activities.
Why is punishing Aeza an effective solution in the fight against cybercrime?
Instead of tracking down individual criminals after attacks occur, the U.S. Department of the Treasury has chosen to strangle the technical infrastructure supporting the entire criminal supply chain. The Aeza Group provides absolute, hard-to-detect and hard-to-take-down hosting services, catering to various types of serious cyberattacks.
This measure undermines the foundation for ransomware operations, data theft, and other dangerous activities by cutting off the digital infrastructure resources that organized crime needs. This is a continuation of similar sanctions against ZServers earlier in 2025, demonstrating synergy and resilience in global cybersecurity protection strategies.
Wiping out 'bulletproof' hosting providers will significantly reduce the ability to sustain large-scale cyberattacks and weaken the criminal operation chain.

Frequently Asked Questions
What is bulletproof hosting? It is a web hosting service that protects data from being taken down, often used by cybercriminals for long-term operations, resisting intervention from authorities. What is OFAC and what is its role? The Office of Foreign Assets Control (OFAC) is responsible for detecting and preventing the assets and infrastructure of international criminal activities, including cybercrime. How do sanctions affect Aeza Group? Sanctions cut off Aeza's ability to receive payments from clients, significantly hindering its ability to maintain illegal operations. Why is the TRON address being scrutinized? This address is an important payment intermediary that helps conceal transactions, thus it is closely monitored by OFAC and Chainalysis. Is the strategy of countering cybercrime through infrastructure effective? Experts evaluate this strategy as essential, as disrupting the infrastructure will interrupt the entire criminal supply chain rather than just addressing the aftermath.
