First VPN Service Taken Offline Following Ransomware and Data Theft Investigation


 

Cybercrime has become increasingly challenging as efforts to disrupt it have shifted beyond the threat actors themselves towards the infrastructure that enables them to operate at scale have increased. First VPN has been dismantled in a significant enforcement action targeting that ecosystem by authorities. First VPN was alleged to be used as a means of concealing malicious activity and evading investigation by ransomware operators, fraud networks, and data thieves. 

Through the coordinated operation, infrastructure spanning dozens of countries was seized, a suspected administrator was identified, and a service disrupted that investigators say had become a recurring element within major cybercrime investigations.

In light of this development, the focus has shifted away from pursuing the individuals responsible for carrying out illicit operations to dismantling the technical foundations which support illicit operations. Despite playing a legitimate role in modern cybersecurity by encrypting internet traffic, masking IP addresses, and facilitating secure communications across untrusted networks, virtual private network services have also been used to conceal malicious activities.

It has been alleged that First VPN developed beyond a conventional privacy service, becoming an integral part of the cybercriminal infrastructure stack, providing threat actors with a means for concealing operating footprints, anonymizing network activity, and complicating attribution. Europol reports that references to the service have surfaced repeatedly throughout nearly every major cybercrime investigation it has assisted, highlighting its extensive use in preventing money laundering, fraud, and identity theft.

On the 19th and 20th of May, authorities conducted a coordinated enforcement action targeting the infrastructure supporting the service, interviewed its suspected administrator, and conducted a house search in Ukraine while at the same time dismantling 33 servers and disrupting global systems thought to facilitate criminal activity. 

Additionally, the operation resulted in the seizure of core domains, including 1vpns.com, 1vpns.net, and 1vpns.org, and associated onion services, effectively removing key access points relied upon by its user base. Further, investigators informed users that the service had been discontinued and that they were being scrutinized by law enforcement.

The platform was taken down as a result of an investigation initiated in December 2021 in which Europol's European Cybercrime Centre and cybersecurity firm Bitdefender assisted authorities in gaining access to the platform's infrastructure and user database. By analysing the collected data, investigators were able to map VPN connections that were believed to facilitate criminal activity, uncovered intelligence on thousands of users, and generated actionable leads related to ransomware campaigns, fraud networks, and other serious cyber-enabled crimes across multiple jurisdictions. 

The investigation has also revealed a fundamental contradiction in the core of criminal anonymity services, namely, that the promise of complete invisibility is very often dependent on the trustworthiness of the very operators who earn their profits from that promise.

It has been alleged that intelligence recovered during Operation Saffron included a database of VPN users which was capable of identifying specific VPN activities and individuals. This raises serious concerns about the extent to which a service that reportedly marketed itself as unreachable by law enforcement retains data. These findings are consistent with a recurring reality within the underground economy, in which threat actors routinely entrust operational trust in infrastructure providers whose internal practices remain opaque and largely undisclosed. 

Considering the investigation of First VPN as part of the cybercrime supply chain, First VPN plays an essential role in enabling malicious actors to maintain operations while minimizing their vulnerability to detection and attribution. The dismantling of its operations aligns with Europol’s broader strategic approach to targeting shared infrastructure rather than individual groups in isolation. 

By disrupting common operational dependencies, multiple criminal networks can be affected simultaneously, resulting in cascading effects. It is evident that this approach has both effectiveness and limitations, as demonstrated by enforcement actions against Safe-Inet in 2020 and VPNLab.net in 2022. 

Cybercriminal operators frequently migrate to alternative providers during such operations; however, the intelligence obtained as a result of such operations frequently exceeds the value of infrastructure seizures over the long run. The investigation into First VPN resulted in a significant amount of operational intelligence obtained by investigators. This information has already been translated into tangible investigation outcomes for the investigation. 

Over 80 intelligence packages have been disseminated globally, 506 known users of the service were identified, and at least 21 investigations have been supported by the information derived from the operation. 

The recovered dataset not only exposes individuals allegedly involved in ransomware campaigns and fraud operations, but also enables law enforcement agencies to map relationships, infrastructure dependencies, and historical activity patterns that would otherwise remain concealed behind layers of anonymity.

According to industry observers, this intelligence-driven approach is increasingly based on the evolving nature of cybercrime disruption, in which not only is it advantageous to eliminate malicious infrastructure but also to turn seized systems into sources of actionable intelligence that can assist law enforcement efforts across jurisdictions in coordinating enforcement efforts. 

Dismantling First VPN illustrates an emerging reality in cybercrime enforcement: it is becoming increasingly necessary to target infrastructure providers and technology companies that enable malicious activity, as well as the actors committing the crime. 

Cybercriminal ecosystems have repeatedly demonstrated the capability to adapt and rebuild, but the information recovered from such operations can serve as a lasting investigative tool that extends beyond the initial takedown. 

As a result of this development, organizations must continuously evaluate the assumptions surrounding trust regarding anonymization services, proxy networks, and other privacy-focused infrastructure within security monitoring strategies, especially since they serve as a reminder. 

Continuing to evolve threat actors' tactics, it is critical to maintain visibility into remote access activity, strengthen identity controls, and apply risk-based authentication. In addition to the increasing efforts of law enforcement and cybersecurity partners against cybercrime's infrastructure layer, the contest is increasingly driven by intelligence, attribution, and operational resilience.

ISPsystem VMs Hijacked for Silent Ransomware Distribution


 

The evolution of cybercrime has led to infrastructure becoming less of a matter of ownership and more of a convenience issue. As opposed to investing time and resources in the construction and maintenance of dedicated command-and-control servers, ransomware operators are increasingly renting inexpensive virtual machines that blend seamlessly into legitimate hosting environments as a practical alternative. 

As a result of this shift, attackers have enhanced their operational strategy by embedding their activities within widely used infrastructure, thereby gaining scalability, plausible deniability, and operational resilience. 

In the event of the disruption of one node, dozens, sometimes hundreds, of nearly identical systems continue to run in parallel, ensuring that campaigns continue uninterrupted. 

Sophos investigators, following this operational shift, identified a series of recent WantToCry ransomware attacks that were triggered by virtual machines that were provisioned through infrastructure managed by ISPsystem, a legitimate provider of virtualization and hosting control panels. 

In forensic analysis of several incidents, researchers observed an underlying pattern: attackers controlled Windows virtual machines whose hostnames were the same. 

As the systems appeared to have been deployed using default Windows templates from ISPsystem's VMmanager platform, it can be deduced that threat actors were utilizing standardized rather than customized builds. 

Based on the correlation between telemetry and sinkhole data, it was found that the same hostname conventions were shared among infrastructures associated with multiple ransomware operations, including LockBit, Qilin, Conti, BlackCat, also known as ALPHV, and Ursnif, a banking trojan. In addition to ransomware, infrastructure overlaps with campaigns distributing information-stealing malware, such as RedLine and Lumma. 

A high frequency of identical system identifiers between geographically dispersed incidents indicates the reuse of templates rather than isolated deployments within the virtual environment. ISPsystem's VMmanager platform facilitates rapid provisioning and lifecycle management of Windows and Linux virtual machines, making it widely used by hosting providers. 

According to Sophos, the default Windows images in VMmanager use the same hostname and certain system identifiers upon deployment. Within benign environments, such uniformity may go unnoticed, while within hostile environments, it becomes a disguise.

The bulletproof hosting operators exploit this architectural feature by enabling their clients to instantiate virtual machines en masse, which allow malicious command-and-control and payload delivery servers to be embedded within pools of otherwise legitimate systems. The result is infrastructure dilution: malicious nodes become statistically indistinguishable from thousands of benign peers, resulting in a challenge in attribution efforts and a reduced likelihood of swift remediation. 

Several of these virtual machines had a concentration that was not evenly distributed. A significant proportion were traced to a small number of hosting providers with history of abuse complaints or regulatory scrutiny, such as Stark Industries Solutions Ltd., Zomro B.V., First Server Limited, Partner Hosting LTD, and JSC IOT. 

Moreover, researchers identified MasterRDP as a recurrent element in the ecosystem, providing VPS and RDP services that are resistant to legal intervention while maintaining direct control over physical infrastructure. The Sophos analysis revealed that over 95 percent of ISPsystem virtual machines with internet-facing hostnames came from four default Windows hostnames generated by ISPsystems. 

There was a correlation between each of these identifiers and detected cybercriminal activity, strengthening the assertion that templated infrastructure is being systematically repurposed to sustain large-scale ransomware and malware operations. 

After expanding their dataset, the researchers identified over 7,000 internet-facing servers sharing one autogenerated hostname, which were spread across Russian, multiple European countries, the United States, as well as Iran and Israel. According to Sophos' Counter Threat Unit, two hostnames in particular recurred consistently both in the WantToCry investigation and in the reporting of general threat intelligence. 

The identifiers identified in this report were not restricted to one particular campaign. Observations from third parties and telemetry correlated them with operations involving LockBit, Qilin, and BlackCat, as well as NetSupport RAT deployments. 

Among the uses of these systems have been host-and-control servers for ransomware, secondary malware payloads distribution, phishing campaigns, botnet management, and staging exfiltrated data for monetization. This pattern of reusable infrastructure templates is likely to have persisted for a minimum of five years, according to investigators.

Ironically, despite the strategy reducing operational costs and speeding up deployment for threat actors, it introduces a measurable signature. Defenders can benefit from the widespread reuse of static hostnames across thousands of ISPsystem-provided virtual machines by clustering these hosts into clusters that can be useful for attribution and campaign tracking. 

Virtual machines were identified by a narrow group of hosting providers, including several companies which have been repeatedly linked to cybercriminal or state-sponsored activity. According to Sophos, some legitimate traffic may originate from these environments, however additional intelligence identifies Stark Industries Solutions Ltd. as the most prominent provider.

Cybercriminal ecosystems and Russian state-sponsored operations are linked to First Server Limited and First Server Limited. Regulatory scrutiny has followed the establishment of Stark Industries in early 2022, shortly prior to the Russian invasion of Ukraine. Several threat groups have been observed to leverage Stark Industries' infrastructure since that time. 

Stark Industries Solutions and its operators were imposed restrictive measures by the European Council in May of last year for their involvement in destabilizing activities by Russian state-affiliated actors, based on their role in facilitating such activities.

Due to its apparent connection with Doppelganger, a Russian disinformation campaign sanctioned by the UK government in October 2024, First Server Limited has also received attention. According to our assessment, MasterRDP is among a number of bulletproof hosting providers that lease ISPsystem managed virtual machines on abuse-tolerant infrastructure to customers who conduct ransomware and malware operations. 

ISPsystem's VMmanager remains a viable and widely used virtualization management platform in the global hosting industry, according to researchers. The software itself is not inherently malicious; however, it is attractive to threat actors seeking scalable infrastructure due to its low cost, ease of onboarding, and rapid deployment capabilities. 

A combination of its widespread user base with its extensive ubiquity allows malicious deployments to maintain operational cover, enabling ransomware and malware campaigns to persist among thousands of routine, compliant virtual machine instances. As a result of these findings, the hosting ecosystem is facing a broader structural challenge. 

Because virtualization platforms reduce infrastructure deployment barriers, security responsibility is increasingly shifting away from providers, resellers, and enterprise customers to ensure that template hygiene is implemented effectively, unique system identifiers are enforced, and anomalous clustering patterns are monitored.

As a result of proactive hostname randomization, stronger customer vetting, transparency in abuse response, and cross-industry intelligence sharing, threat actors may be less likely to use templated infrastructure. 

As demonstrated by these consistent artifacts exposed in the campaign, even commoditized infrastructure leaves discernible patterns behind. It will not be sufficient to dismantle individual malicious nodes. Instead, it will be necessary to address the systemic weaknesses that allow legitimate technology to be silently adapted for large-scale, persistent cybercrime operations.
