WASHINGTON Today, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) is designating Aeza Group, a bulletproof hosting (BPH) services provider, for its role in supporting cybercriminal activity targeting victims in the United States and around the world. BPH service providers sell access to specialized servers and other computer infrastructure designed to help cybercriminals like ransomware actors, personal information stealers, and drug vendors evade detection and resist law enforcement attempts to disrupt their malicious activities. OFAC is also designating two affiliated companies and four individuals who are Aeza Group leaders. Finally, in coordination with the United Kingdom’s (UK) National Crime Agency (NCA), OFAC is designating an Aeza Group front company in the UK.
“Cybercriminals continue to rely heavily on BPH service providers like Aeza Group to facilitate disruptive ransomware attacks, steal U.S. technology, and sell black-market drugs,” said Acting Under Secretary of the Treasury for Terrorism and Financial Intelligence Bradley T. Smith. “Treasury, in close coordination with the UK and our other international partners, remains resolved to expose the critical nodes, infrastructure, and individuals that underpin this criminal ecosystem.”
Today’s action is being taken pursuant to Executive Order (E.O.) 13694, as further amended, and builds on OFAC’s February action targeting ZServers BPH. Today’s action also reflects Treasury’s continued work to combat cybercrime and degrade the support networks that enable malicious actors to target U.S. citizens, technology, and critical industries.
AEZA GROUP: KEY TECHNICAL SUPPORT FOR RANSOMWARE GROUPS, CYBERCRIME, AND ILLICIT DRUGS
Aeza Group, headquartered in St. Petersburg, Russia, has provided BPH services to ransomware and malware groups such as the Meduza and Lumma infostealer operators, who have used the hosting service to target the U.S. defense industrial base and technology companies, among other victims globally. Infostealers are often used to harvest personal identifying information, passwords, and other sensitive credentials from compromised victims. These credentials are then often sold on darknet markets for profit, making infostealer operators a key piece of the cybercrime ecosystem.
Aeza Group has also hosted BianLian ransomware, RedLine infostealer panels, and BlackSprut, a Russian darknet marketplace for illicit drugs. Darknet drug marketplaces allow for the anonymous purchase and shipment of narcotics over the internet, making them a present and increasing contributor to drug trafficking to the United States and worldwide. According to Treasury’s Financial Crimes Enforcement Network (FinCEN) and its supplemental advisory on fentanyl, criminal organizations use darknet marketplaces to sell precursor chemicals and manufacturing equipment used for the synthesis of fentanyl and other synthetic opioids, as well as to traffic fentanyl and other narcotics into the United States.
OFAC is designating Aeza Group pursuant to E.O. 13694, as further amended by E.O. 14144 and E.O. 14306, for being responsible or complicit in, or having engaged in, directly or indirectly, cyber-enabled activities originating from, or directed by persons located, in whole or in part, outside the United States that are reasonably likely to result in, or have materially contributed to, a threat to the national security, foreign policy, or economic health or financial stability of the United States, and that have the purpose of or involve causing a misappropriation of funds or economic resources, intellectual property, proprietary or business confidential information, personal identifiers, or financial information for commercial or competitive advantage or private financial gain.
Aeza International Ltd. is the United Kingdom branch of Aeza Group. Aeza Group uses Aeza International to lease IP addresses to cybercriminals, including Meduza infostealer operators.
Aeza Logistic LLC and Cloud Solutions LLC are Russia-based subsidiaries that are 100% owned by Aeza Group. Servers BPH.
In an effort to evade detection, cybercriminals are increasingly turning to “residential proxy” services that cover their tracks by making it look like everyday online activity.
For years, gray-market services known as “bulletproof” hosts have been a key tool for cybercriminals looking to anonymously maintain web infrastructure with no questions asked. But as global law enforcement scrambles to crack down on digital threats, they have developed strategies for getting customer information from these hosts and have increasingly targeted the people behind the services with indictments. At the cybercrime-focused conference Sleuthcon in in Arlington, Virginia, today, researcher Thibault Seret outlined how this shift has pushed both bulletproof hosting companies and criminal customers toward an alternative approach.
Rather than relying on web hosts to find ways of operating outside law enforcement's reach, some service providers have turned to offering purpose-built VPNs and other proxy services as a way of rotating and masking customer IP addresses and offering infrastructure that either intentionally doesn't log traffic or mixes traffic from many sources together. And while the technology isn't new, Seret and other researchers emphasized to WIRED that the transition to using proxies among cybercrminals over the last couple of years is significant.

NoName057(16) relies heavily on HTTPS application-layer DDoS attacks, with many attacks repeatedly sourced from the same attack harness, networks, and targeting similar countries and industries.
In 2020, the United States brought charges against four men accused of building a bulletproof hosting empire that once dominated the Russian cybercrime industry and supported multiple organized cybercrime groups. All four pleaded guilty to conspiracy and racketeering charges. But…
