In May 2025, the European Union levied financial sanctions on the owners of Stark Industries Solutions Ltd., a bulletproof hosting provider that materialized two weeks before Russia invaded Ukraine and quickly became a top source of Kremlin-linked cyberattacks and disinformation campaigns.…

Materializing just two weeks before Russia invaded Ukraine in 2022, Stark Industries Solutions became a frequent source of massive DDoS attacks, Russian-language proxy and VPN services, malware tied to Russia-backed hacking groups, and fake news. ISPs like Stark are called “bulletproof” providers when they cultivate a reputation for ignoring any abuse complaints or police inquiries about activity on their networks.

In May 2025, the European Union sanctioned one of Stark’s two main conduits to the larger Internet — Moldova-based PQ Hosting — as well as the company’s Moldovan owners Yuri and Ivan Neculiti. The EU Commission said the Neculiti brothers and PQ Hosting were linked to Russia’s hybrid warfare efforts.

But a new report from Recorded Future finds that just prior to the sanctions being announced, Stark rebranded to the[.]hosting, under control of the Dutch entity WorkTitans BV (AS209847) on June 24, 2025. The Neculiti brothers reportedly got a heads up roughly 12 days before the sanctions were announced, when Moldovan and EU media reported on the forthcoming inclusion of the Neculiti brothers in the sanctions package.

In response, the Neculiti brothers moved much of Stark’s considerable address space and other resources over to a new company in Moldova called PQ Hosting Plus S.R.L., an entity reportedly connected to the Neculiti brothers thanks to the re-use of a phone number from the original PQ Hosting.

“Although the majority of associated infrastructure remains attributable to Stark Industries, these changes likely reflect an attempt to obfuscate ownership and sustain hosting services under new legal and network entities,” Recorded Future observed.

Neither the Recorded Future report nor the May 2025 sanctions from the EU mentioned a second critical pillar of Stark’s network that KrebsOnSecurity identified in a May 2024 profile on the notorious bulletproof hoster: The Netherlands-based hosting provider MIRhosting.

MIRhosting is operated by 38-year old Andrey Nesterenko, whose personal website says he is an accomplished concert pianist who began performing publicly at a young age. DomainTools says mirhosting[.]com is registered to Mr. Nesterenko and to Innovation IT Solutions Corp, which lists addresses in London and in Nesterenko’s stated hometown of Nizhny Novgorod, Russia.
According to the book Inside Cyber Warfare by Jeffrey Carr, Innovation IT Solutions Corp. was responsible for hosting StopGeorgia[.]ru, a hacktivist website for organizing cyberattacks against Georgia that appeared at the same time Russian forces invaded the former Soviet nation in 2008. That conflict was thought to be the first war ever fought in which a notable cyberattack and an actual military engagement happened simultaneously.

Mr. Nesterenko did not respond to requests for comment. In May 2024, Mr. Nesterenko said he couldn’t verify whether StopGeorgia was ever a customer because they didn’t keep records going back that far. But he maintained that Stark Industries Solutions Inc. was merely one client of many, and claimed MIRhosting had not received any actionable complaints about abuse on Stark.

However, it appears that MIRhosting is once again the new home of Stark Industries, and that MIRhosting employees are managing both the[.]hosting and WorkTitans — the primary beneficiaries of Stark’s assets.

A copy of the incorporation documents for WorkTitans BV obtained from the Dutch Chamber of Commerce shows WorkTitans also does business under the names Misfits Media and and WT Hosting (considering Stark’s historical connection to Russian disinformation websites, “Misfits Media” is a bit on the nose).
The incorporation document says the company was formed in 2019 by a y.zinad@worktitans.nl. That email address corresponds to a LinkedIn account for a Youssef Zinad, who says their personal websites are worktitans[.]nl and custom-solution[.]nl. The profile also links to a website (etripleasims dot nl) that LinkedIn currently blocks as malicious. All of these websites are or were hosted at MIRhosting.

Although Mr. Zinad’s LinkedIn profile does not mention any employment at MIRhosting, virtually all of his LinkedIn posts over the past year have been reposts of advertisements for MIRhosting’s services.

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.
