An alternative approach to domain-name management: domain leasing

by David Barnett and Daniel Smith-Juggins

Summary 

For many organisations and events, their domain name is the key element behind their public-facing website. However, domains can be managed in a range of ways, despite most frequently being purchased specifically for the use-case in mind. In this article, we explore the model of domain leasing, which can be a practical alternative for usage with short-lived events, competitions or marketing initiatives, and provides the potential for one party to retain ownership of a domain whilst allowing another to make use of it. 

Overview  

Leasing of domains is a practice whereby the owner (registrant) of a domain name enters into a contractual paid agreement[1] with a third party to utilise that domain for a period of time. In such an agreement, the listed registered owner of the domain remains unchanged, but the arrangement typically involves the reconfiguration of the domain's DNS settings to point at the lessee's desired content (potentially including use of e-mail functionality and creation of subdomains)[2,3]. The practice may also be referred to as domain 'renting', a term which is normally utilised for shorter-term agreements[4]

From a lessor's point of view, this type of agreement allows them to retain ultimate control and ownership of the domain name whilst generating revenue from their asset, while the lessee is able to make use of a (potentially high-value) domain (perhaps just for a limited period of time) without needing to provide a sizeable upfront payment - say, for a newly-launched business or short-term campaign. In some cases, a leasing agreement might also include an option for subsequent purchase. A leasing agreement also potentially involves a lower level of legal liability for the lessee against infringement claims. The model might typically also be appropriate for a brand owner working with franchisees or local representatives, and can lend itself to application for dot-brand domains. 

Domain leasing is most usually carried out via dedicated platforms (such as venture.com) or domain marketplaces, or through legal service providers, domain brokers or direct negotiation. Leasing costs are highly variable but might typically range up to thousands of dollars per month (plus associated costs) for a premium domain - such as a short, memorable dictionary word on a popular TLD. For example, as of the time of writing (03-Jul-2024), domains featured on Venture's website[5] include chatroom[.]org ($2.5k/mon), wishes[.]com ($3k/mon), eyelashes[.]com ($5k/mon) and driver[.]com ($15k/mon). For comparison, purchase of premium domains can involve multi-million-dollar prices; Wikipedia[6] lists over 40 domains which have sold for over $3M over the last twenty-plus years, including shop[.]com ($3.55M), clothes[.]com ($4.9M), casino[.]com ($5.5M), hotels[.]com ($11M), sex[.]com ($13M) and voice[.]com ($30M). More recently (reported in March 2023), OpenAI bought AI[.]com for $11M[7].

As an indicator of the types of domains typically associated with leasing agreements, we consider a sample set of (alphabetically, the first-listed) 1,000 domains under the management of leasing service provider Venture (as determined by nameserver analysis). The domains are overwhelmingly dominated by .com examples (984 instances), with the remainder comprised of .org (14) and .net (2). The domains range in length from 3 to 25 characters[8], with four-character domain names by far the most popular (Figure 1).

Figure 1: Distribution of SLD lengths of a sample of 1,000 domains under management by Venture

The longest domains in the dataset comprise entirely of examples where the SLDs are phrases consisting of dictionary words, with the three longest examples found to be americanconservativeunion.com (25 characters), adjustablemortgagerates.com (23) and automobiletransmissions.com (23). The vast majority of the mid-length examples also have SLDs consisting of phrasal word-pairs, with examples such as 'activefamily', 'airlinemeals', 'ancientworld', 'atlanticcity', 'baseballcaps', 'bathcabinets', 'bigdiscounts' and 'budgetprices' (all 12-character names). 

Practical considerations 

For brand owners, there are some key overall points to bear in mind when considering domain leasing. Some useful questions to consider prior to any contractual arrangement include: 

  • Aim - is the domain being used as a revenue generator (e.g. from a premium domain) or a short-term campaign / project run by a corporate entity? 
  • History - how has the domain been used previously? 
  • Ownership - who should retain ultimate control?  
  • Payment - how much is the lessee paying the lessor and when are the payments expected? 
  • Term - how long will the lease last? If a term is specified, is there a clear end date in any agreement? Should there be a provision for an outright purchase at the end?  
  • Indemnity - is there a clause indemnifying the lessor for any liability by the lessee in using the domain? 
  • Licence - what type of licence is needed (e.g. non-exhaustive, exhaustive, or a sole licence)?
  • Termination - are there provisions in place for early termination?  

Conclusion 

Domain leasing can be a useful alternative to purchasing, offering a brand owner a model whereby they can retain ownership of the (potentially high-value) asset, whilst giving a partner entity the opportunity to make use of its functionality. This operational framework, which generally requires a pre-defined contractual agreement, can be of particular applicability in situations where a franchising model is in place, or for short-lived events and campaigns.

An unnatural .bond: a study of a ‘megacluster’ of malware domains

A recent news story[1], following research from security provider Infoblox, highlighted the case of the 'Revolver Rabbit' cybercriminal gang, who have registered more than half-a-million domains to be used for the distribution of information-stealing malware. The gang make use of automated algorithms to register their domains, but unlike the long, pseudo-random ('high entropy'[2,3]) domain names frequently associated with such tools, the Revolver Rabbit domains instead tend to consist of hyphen-separated dictionary words (presumably so as to obfuscate their true purpose), with a string of digits at the end. The majority of their domains (approximately 500,000, i.e. 500k) were hosted on the .bond TLD (top-level domain, or domain extension), but with around 200k more reported across other TLDs.

As an investigation into the scale and execution of the campaign, I first consider domains with names of the relevant format with the .bond extension. As of the date of analysis (22-Jul-2024), the .bond zone-file (providing a comprehensive list of all domains currently registered across the extension) was unavailable for analysis; however, data from a third-party source[4] contained a similar number (actually slightly more) of .bond domains (385k) as DomainTools'[5], estimate of the total number registered across the extension (377k), and was therefore used instead for this study.

The study considers all .bond domains containing (at least) two hyphens, with the second hyphen immediately followed by a numerical digit[6]. This yields a dataset of just over 280k domains (actually over 70% of all domains registered on the TLD), and perhaps (in view of the previously reported estimate of 500k domains) suggests that a significant number of additional domains registered for use in the campaign may subsequently have lapsed. In order to provide an overview of the key features of the domains, I next consider a sample of 1,000 of these domains (actually the first 1,000 alphabetically). They show a number of features in common, including repeated use of the same registrars (with Key-Systems accounting for 985, and NameCheap for 15) and registrants (with registrant e-mail addresses @domain-contact.org given in 864 cases, @key-systems.net in 121, and @uptakeleads.com, @namecheap.com, and @withheldforprivacy.com in the remainder), and registration (domain creation) dates all within a relatively narrow time window (with 897 (89.7%) of the domains registered in the period since 29-May-2024, also noting that the most recent registration date was 20-Jul-2024, indicating that the campaign was likely still ongoing as of the date of analysis). These types of insights are key to the ability to 'cluster' together findings and establish likely connections between them[7].

Figure 1: Numbers of potential ('candidate') .bond malware domains by date of creation, from the sample of 1,000

At the time of the study, none of these domains resolved to any significant content other than pages of pay-per-click (PPC) advertisements, presumably emplaced as a means of monetising the domains - whose purchase has potentially involved an investment of over $1 million - between periods of alternative use. The lack of any more meaningful site content suggests either that the malware distribution takes place from 'deeper' pages of the sites, or that the domains may be utilised only for short periods of activity and are now either dormant or pending activation. There is also a suggestion from previous research that the majority of the domains may have been registered as 'decoys' to mask the small number of active examples.

Returning to the full set of 280k .bond candidate malware domains, the data actually shows a range of domain-name structure patterns, featuring examples with between 2 and 8 distinct strings (keywords) separated by hyphens (Figure 2). The longest identified domain containing 8 keywords - which may not necessarily be part of the Revolver Rabbit cluster - is es-sicily-and-south-of-italy-tour-packages-27j.bond.

Figure 2: Numbers of domains in the dataset by number of distinct keywords contained within the domain name

The dataset also features a number of 'sub-clusters', in which the same keyword pairs are used multiple times. The top ten most frequently occurring pairs are shown in Table 1.

String
                                                
No. instances
                                                
  dental-implants 8,130
  car-deals 4,401
  development-training 3,958
  influencer-marketing 3,854
  design-courses 3,333
  warehouse-inventory 3,040
  systems-panels 2,837
  air-condition 2,752
  warehouse-services 2,735
  electric-cars 2,545

Table 1: Top ten most frequently occurring keyword pairs (i.e. the string appearing immediately prior to the hyphen which is followed by a digit) within the dataset of 280k candidate domains

In these cases, the sub-clusters tend to feature domains where (only) the numerical string differs between the various examples; the first five 'dental-implants' domains (for example) are alphabetically: dental-implants-001.bond, dental-implants-01.bond, dental-implants-02.bond, dental-implants-024.bond, and dental-implants-0243.bond.

Next, it is informative to widen out the search across other gTLDs for which zone-file information is available, to determine how many domains with names of the same format appear across these other extensions. This search actually reveals over 354k more domains, for which the top twenty most frequently occurring domain extensions are shown in Table 2.

  buzz 2,922
  fun 1,505
  store 1,468

Table 2: Top twenty most frequently occurring TLDs in the dataset of additional candidate Revolver Rabbit malware domains (outside .bond)

Outside the group of TLDs within the table which are popular generally, it is striking that this list contains many new-gTLD extensions which have previously been noted as being associated with high rates of infringement and abuse, due to factors such as the ease and cost of registrations, and provider security policies[8]. For example, seven of the top-ten gTLDs found by Spamhaus to have the greatest rates of association with malware[9] appear also in the list in Table 2.

Overall, this analysis suggests that over 600k domains potentially associated with the Revolver Rabbit malware distribution campaign are still actively registered, together with others which may have been used previously and subsequently allowed to lapse. Given the costs of domain registrations, this suggests a substantial financial investment on the part of the cybercriminals, and provides an indication of the amount of revenue these malware campaigns may be able to generate, through the utilisation and sale of stolen credentials - in addition to any further profits which may be available through domain monetisation processes, such as the inclusion of PPC links on the sites.

The findings also provide an indication of the importance of brand-protection programmes encompassing both monitoring and enforcement - specifically in cases where particular brands or company customer bases are targeted. This particular case study highlights the difficulty in proactively monitoring for criminal activity (or other abuse) in cases where there are (for example) no specific strings (such as brand names) to monitor for in the infringing domain names. In these instances, it is necessary to make use of other domain-name characteristics, which are often less diagnostic or more 'fuzzy' in nature - such as shared registration details or similar domain-name structures or keyword patterns - which, when considered together, can identify links between otherwise apparently unrelated findings and establish the existence of 'clusters' of associated results.

Three('s a Crowd)Strikes and You’re Out: Infringing domain registrations after a bug in CrowdStrike's antivirus software

Overview 

The recent bug in CrowdStrike's 'Falcon Sensor' antivirus software, which triggered errors in around 8.5 million Microsoft Windows systems worldwide, has been compared to the 2017 WannaCry ransomware attack. However, it is at least an order of magnitude more significant in terms of impact. In this article, we consider the spike in potentially infringing CrowdStrike-related domain registrations which immediately followed the emergence of the issue. 

Introduction 

The corruption of a CrowdStrike software update led to massive IT outages across the world, affecting a range of industries, including aviation, healthcare and banking - and causing a large drop in CrowdStrike's share price[1]. A fix was deployed relatively quickly, but - as is unsurprising, following similar patterns which have arisen in response to a huge variety of prior events - the issue was exploited by a range of bad actors capitalising on increased public interest in the CrowdStrike brand and users seeking information and assistance. One manifestation of this activity was a spike in the numbers of related domain registrations, as initially reported by security service provider Secureworks[2,3], with warnings also being given about the likelihood of a continuation of scam activity[4].  

Domain registration analysis 

In order to assess the scale of the infringing domain registrations issue, we consider the set of gTLD[5] domains with names containing the CrowdStrike brand name, through analysis of domain zone-file data. As of the date of analysis (22-Jul-2024), 692 such domains were identified, of which 475 were likely official (i.e. under the ownership of CrowdStrike). Of the remainder, domain creation dates were available (via automated look-up) for 133 of the domains, of which 69 (52%) were registered in the three-day period between 19 and 21 July (Figure 1).  

Figure 1: Numbers of registered CrowdStrike-related domains, by date of creation (for the last year) 

The statistics provide some indication that the peak in activity has now passed (with 42, 19 and 8 domains registered on each of the last three days, respectively). However, this may in part be due to the fact that new registrations can take up to a few days to appear in the zone files.  

For the 69 domains registered since the emergence of the news story, there is a familiar mix of content types. 26 (37%) do not currently resolve to any live content (14 with no site response, and 12 displaying placeholder pages), which is typical of sites kept in a 'dormant' state before subsequently being 'weaponised'. A further 24 (35%) resolve to pages displaying pay-per-click ads, as a way of monetising the incoming web traffic, in addition to those displaying significant website content (19 instances). The keyword patterns are also informative, with eight of the domains containing 'fix', three containing 'help' and one containing 'support'.  

The active sites are dominated by sites purporting to offer assistance with a fix - either self-implemented (which could present a potential attack route in cases where the information given is not genuine), or offering their own IT support services (Figure 2). Other content types within the dataset include one site encouraging affected users to take legal action, and others featuring general information or parody content.  

Figure 2: Examples of sites hosted on CrowdStrike-related domains and offering assistance with fixes for the issue

Conclusion 

The flurry of infringement activity following the CrowdStrike software bug IT outage provides the most recent illustration of how high-profile events and news stories frequently trigger subsequent spikes in attack numbers and brand abuse. In this case, the infringements pose security risks to customers which can additionally affect company reputation and highlight the need for customer education and awareness campaigns. 

More generally, the study shows the importance of proactive brand protection programmes - particularly during periods of vulnerability following significant stories. These initiatives should incorporate monitoring approaches which are both proactive and reactive - i.e. able to respond to identified patterns and trends in observed infringement activity - in combination with enforcement actions able to rapidly take down threatening content as soon as it appears.

Fail to prepare, and prepare to fail: Olympics domain infringements

The issue

With the 2024 Summer Olympics set to begin in Paris on the 26th July, we have conducted a review of the current landscape of related domain names. Previous studies have noted that high-profile events of this nature tend to be associated with spikes in related infringements, where bad actors take advantage of increased levels of public interest to create scams and misdirect users to their own content.

Methodology

We have considered the set of registered domains (as of 26-Jun-2024) with names containing 'olympic', 'olympique', or 'paris(-)(2)(0)24', which generated over 16,000 results.  After filtering out official registrations and unrelated matches (e.g. those relating to previous competitions or generic use), we are left with  a dataset of just under 1,000 third-party domain names of high potential relevance.

Findings

The domains feature a range of content types, with 550 of the domains (i.e. 57%) not returning any live website response, and several more resolving just to placeholder pages. It is not uncommon for newly registered domains to be left in a 'dormant' state by their registrants, prior to being subsequently 'weaponised' for scam or infringing use, highlighting the importance of monitoring inactive domains of concern for changes in content. Many more of the domains in the dataset resolve to pages explicitly offering the domain name for sale (Figure 1), highlighting also the popularity of domains being registered for monetisation and profit generation.

Figure 1: An example of a page offering the sale of the host domain name (second-level name 'paris2024') and other names relating to the subsequent games

The domains resolving to live content are associated with differing levels of risk. Several are relatively benign (including instances of news or informational sites, claims of affiliation, sites offering related products or services such as accommodation, and references to other events taking place in Paris in 2024). However, a significant number resolve to content which appears to be potentially infringing and are of concern (Figure 2).

Figure 2: Examples of potentially infringing websites hosted on domain names relating to Paris 2024 - top to bottom: potential phishing (in conjunction with references to travel visas); site offering ticket sales; e-commerce site (potential counterfeits); potential piracy (unauthorised streaming) website; site promoting a cryptocurrency scheme; boycott site

Another striking observation is the extent to which the levels of infringing activity ramp up as the event in question approaches, as shown by the registration profile of the high-relevance third-party domains (Figure 3).

Figure 3: Numbers of high-relevance, third-party Paris 2024 domains actively registered, by original month of registration (where available via automated look-up)

New-gTLD domain extensions - many of which have been previously noted as being popular with infringers - feature heavily amongst the dataset, with the top ten extensions in the overall dataset including .store (5th place; 28 instances), .shop (6th; 25), .online (8th; 24) and .site (10th; 16). An interesting observation is the inclusion of the city-specific new-gTLD .paris in the list (4th place; 30 instances). We also see that the most popular registrars in the dataset are retail-grade providers (Table 1) - again traditionally popular with infringers - and the extensive use of privacy protection in the domain whois records (Table 2).

Take-aways

The range of observed infringements highlights the importance of brand owners conducting proactive programmes of monitoring and enforcement, particularly at times when the brand profile is elevated. This simple study has considered just domain-related findings, but in the modern connected Internet, infringements tend to be manifested across a wide range of channels, and a holistic view is key to addressing the issues.

As with previous studies, new-gTLD extensions comprise a significant proportion of the results of interest. It is also noteworthy that, of the new-gTLDs appearing in the top ten extensions in this study's dataset, only one (.shop) is included in the GlobalBlock scheme[1] (subject to a 'premium domain pricing threshold'[2]). Furthermore, any domains featuring additional keywords would also not be covered (noting that the sites shown Figure 2 include examples featuring terms such as 'tickets', 'visa' and 'schedule'), showing the importance of augmenting these types of blocking schemes with more comprehensive online brand protection programmes.

Finally, the prominence of the .paris domain extension within the dataset shows that city-specific TLDs - which are often overlooked - can be of key importance in relation to particular events.

Re-registered domains, spam, and search-engine optimisation

Google has recently announced some changes to their search and prioritisation algorithms, intended to tackle the problem of 'spammy, low-quality content' in search results. Of particular interest are the improvements to the process of handling 'expired domain abuse' - in particular, the addition of options to their spam reporting tool - in response to the previous practice of infringers purchasing expired domains and posting new spam content.

The reasons for repurposing domains can include taking advantage of the higher level of trust associated with the content previously present on the site, to boost the search ranking of the new material[1,2,3,4,5]. This spam content can take a number of forms, including adult or gambling-related material, or blog-style sites promoting third-party content. The use of the practice to promote sites offering the sale of counterfeit goods has also been noted[6,7]. This issue also presents the possibility for increasing the effectiveness of more egregious types of abuse, such as explicit brand impersonation.

As a simple case study into the potential scale of the issue, we have looked at instances of re-registered domains across the .app, .biz and .blog TLDs. These specific extensions were selected due to the fact that they are 'mid-sized', popular TLDs[8] with low-cost, low-restriction registration options, which are generally 'well-trusted' by general Internet users[9,10], but (paradoxically) also include one example (.app) which has previously been noted as being particularly prone to infringement and abuse[11].

In order to carry out the analysis, we consider the set of those domains which were registered between the 03 and 10-Jun-2024, based on a comparison of zone files. Of these, we then consider the subset which had also previously been actively registered as of Q3 2023 (i.e. instances of re-registrations). The statistics for these are shown in Table 1.

TLD

Re-registrations
                                      
  .app 1,427,146 14,862 1,860
  .biz 1,270,822 5,304 744
  .blog 269,389 3,253 199

Table 1: Numbers of registered domains (totals as of 10-Jun-2024), new registrations, and re-registrations for the three TLDs

Of the re-registrations, we then consider those which resolve to live sites (also as of 10-Jun-2024). These are associated with a range of content types, including large numbers resolving just to placeholder or error pages, sites featuring pay-per-click (PPC) links, or pages offering the domains for sale. However, for the analysis, we focus on the subset resolving to 'spammy' content. This determination is - of course - somewhat subjective, but essentially considers material which appears non-legitimate and/or appears to be unrelated to the name of the domain in question. The 'hit-rate' for re-registrations featuring spam content was greatest for .biz (58 identified examples, compared with 5 for .blog, and 4 for .app). It is also worth noting that - particularly for .app - significant numbers of the re-registrations had actually gone dead again by the time of analysis. Many of these featured long, pseudo-random domain names and may be associated with automated registrations used for malicious or infringing purposes[12].

Figure 1 shows four examples of .biz domains featuring 'spammy' content (e.g. adult or gambling/gaming-related material or random blog content) which had (according to information from archive.org) previously resolved to live, apparently legitimate content (for companies or organisations for whom the domain name itself has specific relevance). Some of these domains have long histories, going back a decade or more. They are therefore potentially examples of domains which have been re-registered to take advantage of the previous level of trust in the websites, and their consequent boosted search-engine rankings. Furthermore, some have been re-registered multiple times since their original incarnation. It is also worth noting that, amongst the dataset, we see numerous instances of repeated use of similar site templates, suggesting potential serial infringement by particular entities.

Figure 1: Examples of re-registered .biz domains now resolving to 'spammy' content

The scale of the issue indicates the potential for subsequent abuse and, perhaps even more concerningly, the misplaced belief that the new material has a definitive link with the previous legitimate content. Brand owners should bear this in mind when allowing domains to lapse - which might take place as part of a domain portfolio rationalisation project.

Overall, the Google reporting tool should be welcomed by brand owners. Alongside mechanisms such as the UDRP to address the underlying domain itself, the reporting tool provides another low-cost way of addressing IP infringement in the web and domain space.

Some more new domains in the .locker

Next in line for launch in the new-gTLD programme is the .locker domain-name extension. It entered its Sunrise period on the 19th June 2024, and will go into Early Access on the 18th September 2024 (when domains can be secured at a premium price) and subsequently into General Availability on the 26th September 2024. The extension was originally owned by telecommunications company Dish DBS, before being acquired by Orange Domains in August 2023[1], with the intention of use in conjunction with digital locker services (including both electronic file and physical storage)[2,3].

Like some previous examples - such as .box[4] - the new .locker extension promises to provide dual Web2 / Web3 functionality[5]. This is achieved by it offering integrated support for the Bitcoin protocol, meaning that it will be compatible with applications such as cryptocurrency wallets. The Web3 'digital identity' will be reserved for holders of the corresponding Web2 domain name, but its use will not be compulsory[6].

As of the date of analysis [05-Jun-2024], the .locker zone file contained just a handful of entries[7], comprising reserved domain names relevant to the technical infrastructure of the TLD[8]. However, we would expect the numbers to start ramping up once the Sunrise period opens and brand owners are able to start securing domains, before likely jumping up once again once registrations become generally available to all.

Similarly to .zip, the new extension may be attractive to infringers because of the potential for abuse due to the possibility for confusion with legitimate file-storage solutions. It may also transpire that the TLD will be popular with piracy-related applications, in reference to the old 'cyberlocker' terminology[9] (cf. the potential for the shortly-available .ad extension to be abused for advertising fraud[10]).

In light of this development, brand owners are advised to secure key brand terms and/or keyword strings across the new extension, as soon as purchase is possible - even if only as defensive registrations to prevent fraudulent use. Additionally - as with any emerging area of Internet content - ongoing monitoring of the space will also be advisable, in order to stay one step ahead of the infringers.

A bit of a nasty (anti)virus: the landscape of fake antivirus websites

BLOG POST

Following a recent report by Trellix[1] about bogus websites posing as antivirus providers, we have conducted a landscape review of domains beginning with the names of major antivirus and antimalware providers. The analysis considers all examples where the second-level domain name (SLD) - i.e. the part to the left of the dot - consists only of the brand name, or where any keywords from a set of high-relevance keywords are also present.

New-gTLD extensions feature heavily within the list of 1,440 domains, with .live (106 domains), .online (48), .xyz (33), .site (22) and .shop (19) being the most popular. New-gTLDs are commonly associated with high rates of infringement and abuse, and give rise to particular security concerns in the technology sector, where many of the extensions have specific relevance[2].

The review identified a number of high-concern websites posing direct potential threats, such as those offering (potentially malicious) downloads and instances of user credential collection (i.e. potential phishing). Other identified infringement types included e-commerce sites, offers of discount codes and information sites. Significant numbers of domains where the SLD consisted just of the brand name were also found to be potentially infringing.

Given that this study focuses solely on a small subset of the full range of potentially infringing sites, the number of threatening findings is concerning. This analysis highlights the importance of proactive programmes of brand protection, incorporating a policy of defensive domain registrations (to address the issue of 'brand-only' SLD examples). Other advisable initiatives include greater clarity by brand owners on the identity of their official sites (perhaps involving the use of dot-brand extensions) and engagement with 'fraudcasting' schemes, to push out browser warnings for fraudulent sites.

This specific case of infringements targeting antivirus brands is an interesting one - essentially an instance of 'gamekeeper turned game'. The very nature of these brands is such that consumer trust is a key element (in addition to technical effectiveness), so the emergence of these types of attack poses a real risk to brand reputation and value.

WHITE PAPER

Introduction

A recent report by cybersecurity service provider Trellix[1] highlighted the detection of three fake sites posing as official antivirus providers. In all cases, these sites were offering the download of purported security products, but were actually distributing malicious applications, which aimed to access confidential data, steal information or mine cryptocurrency[2]. As of the time of writing (29-May-2024), only one of these sites (bitdefender-app[.]com) was still active (Figure 1), though all three still generated browser messages warning of dangerous content.

Analysis

As an investigation into the scale of this type of issue, we consider the landscape of domains with names beginning with any one of 16 of the top antivirus and antimalware providers[3,4,5]. It is also worth noting that none of the other potentially threatening examples presented in this article were found to generate browser warnings, an additional factor of concern regarding the potential for exposure of consumers to infringing or harmful content. Analysis is based on zone-file information from ICANN's CZDS service, available for 1,087 gTLDs (domain extensions).

The analysis yielded a dataset of over 14,000 domains, though this will include 'false positives' such as instances where the brand strings appear as sub-strings of longer terms, and references to the brand name in an unrelated context. Accordingly, for the first round of filtering, we considered only those domains where the second-level domain name (SLD) string (i.e. the part of the domain name to the left of the dot) consisted only of the brand name, or where any of the following high-relevance keywords were present in the domain name: virus; malware; secur*, app, download, update, login, scan, protect, enterprise, activat*, defend, online, setup, instal*. This generated a candidate set of just over 1,900 high-relevance domain names. From these, we next removed any which appeared to be under the control of the official brand owner in question, on the basis of the use of an enterprise-class registrar and/or re-direction to a definitively official website. This leaves a set of 1,440 probable third-party domains of potential concern. Significant numbers of these domains utilise new-gTLD extensions, noted in many previous studies as being associated with high rates of infringement and abuse[6]; the new-gTLD extensions with more than 10 domains in the dataset are: .live (106), .online (48), .xyz (33), .site (22), .shop (19), .pro (17), .store (13), .zip (11), .click (11), and .deals (11). 

Of the 1,440 sites, 439 generate a live website response, according to an automated site-visitor script (though this is likely to be a conservative estimate, since some websites will generate a false-negative response - e.g. if the site is slow to respond). 

Amongst the live sites, a range of content types were identified, including instances of unrelated third parties apparently legitimately using the same brand name (particularly where the brand is a relatively generic acronym, such as AVG, or a common name, such as Norton), cases of misdirection to unrelated content (including gambling-related or other undesirable content in some cases), and sites monetised through the inclusion of pay-per-click links, or by displaying pages offering the domain name for sale. There is also the potential for any of these sites to be activated with more significant content at a later date. 

However, the sites currently of highest concern are those displaying official branding, or referencing the brand name in a context relevant to the business area of the brand in question. Some of these sites may be (possibly official, but potentially unauthorised) distributors (Figure 2) or other affiliated organisations (e.g. mcafee[.]education, which re-directs to mcafeeinstitute[.]com). 

Figure 2: Example of a purported official distributor's website (avgverlengen[.]nl, re-directed from avg[.]partners and avg[.]tips)

A number of others have the appearance of legitimate sites, but may be fake - in many cases, a definitive determination is difficult, which is clearly unsatisfactory from a customer confusion point of view. One of the categories of highest concern are those sites where the SLD consists just of the brand name, as these present (if non-legitimate) the highest potential for confusion with genuine sites. The dataset includes a number of such examples, including avast[.]partners, bitdefender[.]digital, bitdefender[.]icu, bitdefender[.]lat, emsisoft[.]lat, eset[.]ovh, f-secure[.]store, surfshark[.]click, and totalav[.]xyz (Figure 3) which, if not official sites under the control of the respective brand owners, pose a serious concern. 

Figure 3: Examples of sites whose legitimacy is unclear (with all five examples registered via privacy protection service providers), and where the SLD consists just of the brand name: bitdefender[.]icu; eset[.]ovh; f-secure[.]store; surfshark[.]click; totalav[.]xyz

Widening out to the larger set of domains which feature additional keywords of relevance, sites featuring a range of content types were identified. These include examples of (potentially non-legitimate or unauthorised) sites featuring e-commerce content (e.g. avastantivirus[.]pro (re-directs to datav[.]fr), bitdefenderantivirus[.]space, kasperskyantivirus[.]space, nortonantivirus[.]space (all re-direct to software-defender[.]com),  malwarebyteschannelstore[.]com, avgonline[.]com, bitdefenderonline[.]com, bitdefenderperu[.]com, malwarebytessoftware[.]com, nortondefenderhub[.]com, norton-setup[.]com), offering coupons, vouchers or discount codes (e.g. bitdefenderantiviruscoupon[.]com), offering product information (e.g. malwarebytesnew[.]com, mcafee-activate[.]xyz, mcafeecom-activatesetup[.]com, mcafeecom-setup[.]com, vipre-antivirus[.]com, avastupdates[.]com, norton-com-setup[.]live, norton-setup[.]net – which actually directs users to a third-party site at fox2[.]kr) and sites making other general claims of affiliation (e.g. bitdefender-indonesia[.]com, bitdefenderkorea[.]com). (Figure 4). 

Figure 4: Example of an e-commerce site (avgonline[.]com), a site offering discount codes (bitdefenderantiviruscoupon[.]com), and an information site (mcafeecom-activatesetup[.]com)

However, the examples of greatest concern, from the point of view of posing direct potential threats, are those offering downloads (which may be malicious) (e.g. surfsharkvpnapp[.]com, kasperskydownload[.]com, mcafeedownload[.]com, spybot-freedownload[.]com, spybot-free-download[.]com, avastlogins[.]com (re-directs to a URL on loneseo[.]tongxinfl[.]cn)) or collecting user credentials (i.e. potential phishing) (e.g. esetprotect[.]cloud, nortonsetup[.]cloud, nortonsetup[.]xyz, trendmicrosetup[.]online) (Figure 5).

Figure 5: Examples of sites offering downloads (surfsharkvpnapp[.]com and avastlogins[.]com) and sites collecting user credentials (nortonsetup[.]cloud and trendmicrosetup[.]online)

It is also worth noting that three of these sites (for example) - nortonsetup[.]cloud, nortonsetup[.]xyz and trendmicrosetup[.]online) - all have a very similar appearance and appear likely to have been generated from a common site template (perhaps as part of a single coordinated campaign by a particular individual infringer). This assertion is strengthened by the facts that all three are registered via 'Privacy Protect, LLC' with Hostinger Operations, UAB as registrar, and all three reference the same hyperlink (http[://]gmpg[.]org[/]xfn[/]11) in the metadata sections of the HTML of the websites. These types of insights are key to the process of 'clustering', a means of drawing links between infringements, and forming the basis for the potential for factors such as building cases of bad-faith and allowing for efficient bulk takedown actions[7].

Discussion

The numbers of results identified in this simple study (considering only 16 antivirus brands, and looking only at branded domain names where the brand name appears at the start) indicates that the scale of the issue of antivirus infringements, scams and fake sites is likely to be considerable, and certainly comprises far more examples than the handful of sites reported in the original article. 

These findings highlight not only the importance of care being taken by consumers, but also the necessity for brand owners - particularly in industries where digital security is such a central concern - to employ comprehensive brand protection programmes comprising monitoring, analysis and enforcement. Defensive domain registrations are also likely to play a significant part of this picture, as shown by (for example) the significant numbers of potential infringements where the second-level domain name consists just of the brand name; for key TLDs, these types of domain names should certainly be kept under the control of the brand owners in question. 

Another point to take away is the importance of organisations communicating the identity of their official site(s) clearly to their customer base, and educating them on the risks of engaging with other unapproved entities. Increased adoption of dot-brand domain-name extensions may be a key part of this solution. Finally, it would also be advantageous for brand owners to more extensively explore schemes to proactively push out alerts to browsers, whenever fake sites are detected or reported[8]
