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. But new findings show those sanctions have done little to stop Stark from simply rebranding and transferring their assets to other corporate entities controlled by its original hosting providers.

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 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.
Mr. Zinad’s LinkedIn profile is full of posts for MIRhosting’s services.
A Google search for Youssef Zinad reveals multiple startup-tracking websites that list him as the founder of the[.]hosting, which censys.io finds is hosted by PQ Hosting Plus S.R.L.
The Dutch Chamber of Commerce document says WorkTitans’ sole shareholder is a company in Almere, Netherlands called Fezzy B.V. Who runs Fezzy? The phone number listed in a Google search for Fezzy B.V. — 31651079755 — also was used to register a Facebook profile for a Youssef Zinad from the same town, according to the breach tracking service Constella Intelligence.
In a series of email exchanges leading up to KrebsOnSecurity’s May 2024 deep dive on Stark, Mr. Nesterenko included Mr. Zinad in the message thread (youssef@mirhosting.com), referring to him as part of the company’s legal team. The Dutch website stagemarkt[.]nl lists Youssef Zinad as an official contact for MIRhosting’s offices in Almere. Mr. Zinad did not respond to requests for comment.
Given the above, it is difficult to argue with the Recorded Future report on Stark’s rebranding, which concluded that “the EU’s sanctioning of Stark Industries was largely ineffective, as affiliated infrastructure remained operational and services were rapidly re-established under new branding, with no significant or lasting disruption.”

The U.S. government today imposed economic sanctions on Funnull Technology Inc., a Philippines-based company that provides computer infrastructure for hundreds of thousands of websites involved in virtual currency investment scams known as “pig butchering.” In January 2025, KrebsOnSecurity detailed how Funnull was being used as a content delivery network that catered to cybercriminals seeking to route their traffic through U.S.-based cloud providers.
“Americans lose billions of dollars annually to these cyber scams, with revenues generated from these crimes rising to record levels in 2024,” reads a statement from the U.S. Department of the Treasury, which sanctioned Funnull and its 40-year-old Chinese administrator Liu Lizhi. “Funnull has directly facilitated several of these schemes, resulting in over $200 million in U.S. victim-reported losses.”
The Treasury Department said Funnull’s operations are linked to the majority of virtual currency investment scam websites reported to the FBI. The agency said Funnull directly facilitated pig butchering and other schemes that resulted in more than $200 million in financial losses by Americans.
Pig butchering is a rampant form of fraud wherein people are lured by flirtatious strangers online into investing in fraudulent cryptocurrency trading platforms. Victims are coached to invest more and more money into what appears to be an extremely profitable trading platform, only to find their money is gone when they wish to cash out.
The scammers often insist that investors pay additional “taxes” on their crypto “earnings” before they can see their invested funds again (spoiler: they never do), and a shocking number of people have lost six figures or more through these pig butchering scams.
KrebsOnSecurity’s January story on Funnull was based on research from the security firm Silent Push, which discovered in October 2024 that a vast number of domains hosted via Funnull were promoting gambling sites that bore the logo of the Suncity Group, a Chinese entity named in a 2024 UN report (PDF) for laundering millions of dollars for the North Korean state-sponsored hacking group Lazarus.
Silent Push found Funnull was a criminal content delivery network (CDN) that carried a great deal of traffic tied to scam websites, funneling the traffic through a dizzying chain of auto-generated domain names and U.S.-based cloud providers before redirecting to malicious or phishous websites. The FBI has released a technical writeup (PDF) of the infrastructure used to manage the malicious Funnull domains between October 2023 and April 2025.

Silent Push revisited Funnull’s infrastructure in January 2025 and found Funnull was still using many of the same Amazon and Microsoft cloud Internet addresses identified as malicious in its October report. Both Amazon and Microsoft pledged to rid their networks of Funnull’s presence following that story, but according to Silent Push’s Zach Edwards only one of those companies has followed through.
Edwards said Silent Push no longer sees Microsoft Internet addresses showing up in Funnull’s infrastructure, while Amazon continues to struggle with removing Funnull servers, including one that appears to have first materialized in 2023.
“Amazon is doing a terrible job — every day since they made those claims to you and us in our public blog they have had IPs still mapped to Funnull, including some that have stayed mapped for inexplicable periods of time,” Edwards said.
Amazon said its Amazon Web Services (AWS) hosting platform actively counters abuse attempts.
“We have stopped hundreds of attempts this year related to this group and we are looking into the information you shared earlier today,” reads a statement shared by Amazon. “If anyone suspects that AWS resources are being used for abusive activity, they can report it to AWS Trust & Safety using the report abuse form here.”
U.S. based cloud providers remain an attractive home base for cybercriminal organizations because many organizations will not be overly aggressive in blocking traffic from U.S.-based cloud networks, as doing so can result in blocking access to many legitimate web destinations that are also on that same shared network segment or host.
What’s more, funneling their bad traffic so that it appears to be coming out of U.S. cloud Internet providers allows cybercriminals to connect to websites from web addresses that are geographically close(r) to their targets and victims (to sidestep location-based security controls by your bank, for example).
Funnull is not the only cybercriminal infrastructure-as-a-service provider that was sanctioned this month: On May 20, 2025, the European Union imposed sanctions on Stark Industries Solutions, an ISP that materialized at the start of Russia’s invasion of Ukraine and has been used as a global proxy network that conceals the true source of cyberattacks and disinformation campaigns against enemies of Russia.
In May 2024, KrebsOnSecurity published a deep dive on Stark Industries Solutions that found much of the malicious traffic traversing Stark’s network (e.g. vulnerability scanning and password brute force attacks) was being bounced through U.S.-based cloud providers. My reporting showed how deeply Stark had penetrated U.S. ISPs, and that its co-founder for many years sold “bulletproof” hosting services that told Russian cybercrime forum customers they would proudly ignore any abuse complaints or police inquiries.

That story examined the history of Stark’s co-founders, Moldovan brothers Ivan and Yuri Neculiti, who each denied past involvement in cybercrime or any current involvement in assisting Russian disinformation efforts or cyberattacks. Nevertheless, the EU sanctioned both brothers as well.
The EU said Stark and the Neculti brothers “enabled various Russian state-sponsored and state-affiliated actors to conduct destabilising activities including coordinated information manipulation and interference and cyber-attacks against the Union and third countries by providing services intended to hide these activities from European law enforcement and security agencies.”
