Cyber threat actors employ a variety of sophisticated methods to sustain their operations and evade detection. One such method involves the procurement of domain names used during malicious activities. Rather than registering domains directly, threat actors often rely on third parties who specialize in providing anonymous and offshore domain acquisition services.
The primary motivation behind this practice is to enhance anonymity and reduce traceability. Direct registration increases the risk of linking domain ownership to threat actors. By leveraging intermediaries and bulletproof service providers entities that intentionally disregard legal and regulatory takedown requests threat actors can significantly mitigate operational risks.
These services typically involve domains registered with fabricated identities, compromised domains, or pre-existing active domains, offering a secure and resilient foundation for malicious operations.
Another important driver for the use of such services is the evasion of Know Your Customer (KYC) requirements and regulatory scrutiny. Legitimate domain registrars often mandate identity verification, making direct registration riskier for threat actors.
Anonymous and offshore services allow them to circumvent these controls, further complicating efforts by law enforcement to trace malicious activities. This approach not only strengthens operational security but also minimizes exposure to legal risks for illicit activities.
Moreover, some offshore providers openly advertise their ability to resist takedown efforts initiated by cybersecurity firms and law enforcement, especially for domains used in phishing campaigns targeting financial institutions or government entities. This reflects a shift from mere anonymity services to active anti-intervention positioning as part of their value proposition.
Our research identified that these services are marketed and sold primarily through two channels: web-based panels and Telegram bots. Additionally, evidence suggests that the offshore and anonymous domain service ecosystem often intertwined with bulletproof hosting operations has been active since the early 2000s:
The offshore domain service sector plays a critical role in enabling and sustaining malicious operations by offering domain registration and hosting solutions that emphasize anonymity, operational security, and flexibility. This sector directly supports activities such as phishing campaigns, ransomware distribution, cryptocurrency theft, and various black-market services by reducing traceability and circumventing traditional detection mechanisms.
Offshore domain providers often work in tandem with bulletproof hosting services, creating robust infrastructures that are highly resistant to legal takedown efforts and automated security controls.
3.1. Purpose and Use Cases of Offshore Domains
Offshore domain services are primarily used for the following purposes:
3.2. Service Providers on Underground Platforms
Many threat actors operating in the offshore domain market present their services through websites that, at first glance, resemble legitimate hosting and domain registration companies. However, upon closer inspection, it becomes evident that these platforms primarily cater to cybercriminals seeking anonymity, operational security, and resilience against takedown attempts.
These service providers often highlight features such as “No KYC“, “Bulletproof policies,” and “instant provisioning,” directly appealing to actors involved in phishing, malware distribution, ransomware operations, and other illicit activities.
During our intelligence research, we identified a threat actor openly advertising “Bulletproof domains” and “DMCA ignored” policies, offering domain services for high-risk activities such as affiliate programs, warez, torrents, and scam pages.
Threat actor emphasizes support for a wide range of controversial and illicit activities, including warez distribution, gambling operations, scam pages, and black-hat marketing campaigns. Prices for domain registration vary depending on the TLD, with payments accepted via cryptocurrencies such as Bitcoin (BTC), Monero (XMR), and Ethereum (ETH).
A threat actor offers offshore domain registration with explicit claims of bulletproof protection and 24/7 customer support through encrypted communication channels.
One such provider distinguishes itself by offering a “content-neutral” hosting policy, alongside fast domain replacement options for flagged or seized domains.

Some offshore providers promote themselves as “trusted platforms for red teamers and private projects,” offering domain registrations without any verification requirements.
In addition to traditional websites, certain services use Telegram bots to automate the ordering process and preserve operational anonymity.
While most offshore providers operate without content restrictions, a minority impose selective limitations to reduce unwanted attention or manage operational risks. For example:
| Analyst Note |
| The presence of content restrictions indicates that some providers seek to balance operational longevity with perceived ethical boundaries, aiming to avoid unwanted scrutiny from law enforcement or regulators. |
In addition to independent websites, many service providers actively advertise their offerings through dark web forums. These posts often include:
Example structure observed during research:
As observed during our investigation, underground bulletproof domain and VPS services are frequently promoted via Telegram using marketing language that closely mirrors that of legitimate infrastructure providers. One such example, originating from a channel, is shown below:
In addition to ransomware and phishing operations, offshore domain services have long been leveraged to facilitate a wide range of illicit trade activities ranging from counterfeit goods and fraudulent services to unlicensed pharmaceuticals-making them accessible on the clear web under a veil of anonymity:
3.3. Services Offered by Threat Actors
Threat actors offering offshore domain services provide a range of features that enhance operational security and usability:
| Analyst Note |
| These features create a robust ecosystem for threat actors, enabling them to establish resilient infrastructure that supports various cybercrime operations. |
Technological Infrastructure of Service Vendors
Offshore and bulletproof hosting service providers typically operate on privacy-oriented, highly resilient infrastructures. These providers are not only theoretically structured but have been directly observed by our team during a case investigation involving a known service that supplies domains to ransomware groups.
Their infrastructure is built on the following technical pillars:
4.1. Observed Technologies in Offshore Infrastructure
In our OSINT-based scanning of servers the following technologies were most commonly observed:
Browser Trust Level: Endpoints are often marked as “Trusted”, despite their use in illicit operations.
Web Server: Nginx – one of the most widely used HTTP servers.
Admin Panel: Webmin – a Linux server management interface, accessible via port 10000.
Remote Access: OpenSSH – standard for secure server connectivity.
WAF/Security Layer: F5 Big-IP Access Policy Manager.
These technologies are composed of widely adopted open-source and commercial solutions. No uncommon or advanced components were identified; the systems are generally built on mainstream, reliable infrastructure choices.
| Analyst Note |
| By configuring their infrastructure with common components like Nginx and Webmin, threat actors ensure both performance and camouflage. The fact that these systems are labeled “Trusted” by browsers delays initial detection and hinders reputation-based filtering mechanisms. |
Offshore Domain Services, Trends, and Crime
Based on our analysis, we identified more than 10 popular offshore domain service providers, each responsible for registering over 1,000 domains. Most ransomware groups and dark web forums also utilize services from offshore domain providers.
During our investigation, we also discovered dedicated providers that exclusively serve crypto drainer groups:
Our findings indicate that the two most frequently used offshore domain providers by threat actors are Offshore Service Provider 1 and Offshore Service Provider 2.
Domains registered via these entities typically appear under the names associated with their respective corporate fronts. The total number of domains registered under these two providers is around 300,000 overall.
A steady increase was observed in offshore domain service activity across Q1 2025, with March showing a more than 50% rise compared to January:
This pattern suggests growing demand for quickly deployable infrastructure, commonly used to facilitate phishing, malware delivery, and command-and-control operations.
The upward trend not only reflects a growing reliance on offshore and bulletproof hosting providers by threat actors, but also points to an acceleration in underground trade between these actors.
Our findings reinforce the connection between domain infrastructure services and ransomware operations, indicating that threat groups function as part of a mutually reinforcing ecosystem, where service provisioning, data extortion, and monetization tactics are increasingly interdependent.
(Note: In the TLP:WHITE version of this report, the real names of these providers are anonymized.)
5.1. Usage Patterns of Offshore Domain Providers
To illustrate the scale and consistency of usage, we identified a representative sample of domain names registered under Offshore Service Provider 1 and Offshore Service Provider 2.
While the full domain names and registrar information have been restricted in this version, the sample clearly reflects a recurring pattern of registrations associated with suspicious or malicious operations.
Note: Full domain details are presented only in the classified version of this report.
Supporting this assessment, our team identified through the analysis of the Black Basta chat leak that domains used in their operational activities had been registered via “Provider 1” offshore service provider with known ties to bulletproof infrastructure.
This finding further reinforces the broader trend of cyber threat actors deliberately leveraging privacy-focused and jurisdictionally distant registrars to obscure infrastructure ownership and hinder attribution efforts.
5.2. Registrar Abuse Response Gap
One of the key factors contributing to the resilience of offshore domain services is the lack of timely and effective abuse handling by certain domain registrars. Despite receiving multiple abuse complaints including those related to phishing, ransomware, and crypto scams some registrars consistently fail to take down malicious domains or respond only after extended delays.
Our research revealed that the majority of domains used by offshore providers were registered via two major registrars, referred to here as Registrar 1 and Registrar 2.
Both entities appear frequently across infrastructure used by ransomware groups, crypto drainers, and phishing campaigns. These registrars are often characterized by:
Historical abuse reports associated with these registrars indicate recurring patterns of delayed or absent takedown responses, reinforcing their position as preferred intermediaries within the underground domain ecosystem.
| Analyst Note |
| The abuse response gap represents a systemic weakness in global domain governance. Threat actors are well aware of this policy blind zone and actively register domains through non-cooperative registrars to extend campaign longevity. |
The following table outlines the observed associations between ransomware groups and the top five offshore domain providers, reflecting their alignment with infrastructure acquired via lenient registrars.

| Analyst Note |
| These service providers, commonly used for illicit activities, host hundreds of thousands of domain names. This widespread infrastructure use demonstrates the critical role such providers play in supporting large-scale phishing and ransomware operations, as well as various other cybercriminal campaigns. |
Conclusion and Evaluation
The continued availability and evolution of offshore domain services significantly contributes to the sustainability of cybercriminal operations. These services act as both a shield and an enabler, protecting the identities of malicious actors while offering the technological capabilities needed for persistent and scalable attacks.
Our analysis of Q1 2025 data reveals a clear upward trend in the underground offering of such services, particularly those related to domain provisioning. This growth reflects an increasing operational dependency on offshore infrastructure among cybercriminal groups, especially in the context of ransomware and data extortion campaigns.
