    An enormous number of look-a-like  domains are registered each year by cybercriminals to imitate well-known companies and gain money. In addition to phishing emails and bogus websites, these domains are also used to divert web traffic and distribute malware.

    To deceive their customers into thinking they’re dealing with well-known businesses, look-alike websites use deceptive tactics to harm established companies’ reputations, financial resources, and customer data. 

    In this article, we will understand what domain attacks are, what makes them possible, and steps to prevent brands from being victims of similar domain attacks.

    Scope of the Problem

    Domain names are used by internet users to discover companies, services, professionals, and personal websites. By registering domain names that appear to be linked to other domains or companies, cybercriminals profit from users’ errors, taking advantage of the internet’s crucial role in domain name registrations. Cybersquatting is a term for this practice.

    In order to carry out domain-based attacks, attackers employ a variety of techniques, including phishing, social engineering, and malware. There are several ways criminals try to evade detection, from mimicking legal websites to depending on subtle differences that fool the untrained eye.

    Tactic 1: Copycatting

    It’s one of the most prevalent methods used by criminals to impersonate your website. In many cases, this is done by choosing an alternate top-level domain, or TLD, or by adding additional TLDs to a domain name. To make people believe they are dealing with a respectable business, attackers often employ these techniques. This makes it easier to carry out phishing or malicious assaults successfully. If a site looks to be authentic, an assault employing a generic, disposable domain will be more successful.

    The logo and brand name of your company will frequently appear on malicious domains in an attempt to fool visitors into thinking they are visiting a legitimate site. Unwitting victims may be persuaded to give personal or financial information or purchase counterfeit items from these sites because of the familiarity and confidence that these sites establish.

    Tactic 2: Piggybacking 

    A common tactic used by cybercriminals is to imitate well-known brands with spoofed or look-alike domains. Either they are parked or they are serving up real-time data, depending on the situation. However, parked domains may be used to quickly display harmful material and make ad income. Another common usage is to deliver material that might jeopardize a brand’s reputation, such as counterfeit goods.

    Tactic 3: Typosquatting and Homoglyphs

    Attackers are constantly on the lookout for new ways to defraud unwary internet users who are unlikely to realize that their traffic is being faked. In addition to typosquatting and homoglyphs, there are a number of other possibilities.

    Using frequent URL misspellings that users are either likely to make on their own or aren’t aware of is known as “typosquatting.” Typo attacks are common when a company has no registered domains that are near to its real domain name. In addition to trademark infringement, attackers may use legal images or other intellectual property to make malicious websites appear to be legitimate.

    Adding a letter to the organization’s name, such as the ‘i’ in the picture below, is an example of this practice:

    Another type of domain spoofing is the use of homoglyph attacks. A look-alike letter from a non-Latin script can be used in these attacks, but the core principles of domain spoofing remain unchanged.

    For example, the Latin “a” is written in Cyrillic as “a.” Despite their superficial similarity, the Unicode values of these letters differ, and as a result, the browser will treat them differently. Attackers have a lot of room to maneuver because of the large number of Unicode characters already in existence. Traditional string matching and anti-abuse algorithms are fooled by impersonators using homoglyph assaults.

    What makes a look-alike domain attack possible?

    There is a structure among the majority of domain threats that appear to be identical. As you can see below, each stage of the creation process is laid out:

    Step 1: Make use of a similar domain name.

    When an attacker is looking for a domain name to spoof, they first check to see if the registrar has any open variants and then register a similar domain name.

    Step 2: Publish DNS records

    Afterward, they set up an A or MX record for email delivery, depending on the situation.

    Steps 3 and 4 (website): Make a website and distribute the URLs.

    Phishing sites are generally secured using free SSL certificates obtained by threat actors. A variety of methods will be used to disseminate the URL of the fake site.

    Steps 5 and 6 (email): Get an email server set up, and then start sending emails.

    Scammers use an email server to create a BEC or ransomware assault, then create and send emails to their intended victims.

    Why domain protection is necessary

    Domain names and the websites they host are critical to an organization’s online reputation and brand. They are often the first point of contact between your organization and a prospective client, business partner, or employee. Cybercriminals are fully aware of this and are attempting to exploit the present situation by launching attacks.

    As a result of malevolent, impersonating websites hurting the brand’s reputation, customers may wish to buy elsewhere.  Both the client and retailer lose money as a consequence, which has a negative impact on both sides.

    Many companies keep tabs on domains relevant to their brand to make sure it is being portrayed correctly. Larger companies with a big number of subsidiary brands may find this approach much more challenging. It’s easy for businesses to become overwhelmed by the volume of notifications because of the pervasive nature of domain attacks. In order to safeguard their brand, products, trademarks, and other intellectual property, businesses must keep a watch out for websites that may be imitating or pirating such items.

    Active monitoring of domains that may infringe on a company’s trademark is the only way to ensure it is protected.

    How to defend against look-alike domains

    An established and continuous strategy for data gathering, curation, and mitigation may help companies effectively handle domain risks. Adopting a multi-pronged strategy is considered excellent practice.

    1. Collection – the gathering of enough domain intelligence to spot possible risks

    2. Curation – intelligence research and development to discover genuine domain dangers and assemble adequate proof

    3. Mitigation – the steps taken to mitigate the risk posed by known domain threats

    Collection

    Organizations require access to new and current registered domain names to identify domain hazards. There are some good domain intelligence resources:

    • TLD zone files keep track of every newly registered domain on a daily basis.
    • For millions of new SSL certificates issued every day, the certificate transparency tracks current domains, subdomains, third-level domains, fourth-level domains, and so on.
    • DNS traffic comprises domain names that are searched and may be used to track new domains.
    • Look-alike versions of valid domains can be used in DNS searches to determine if such look-alike variations exist.

    Domain intelligence gathered from the aforementioned sources can be scrutinized for signs of domain impersonation.

    Curation

    To detect possible risks, domain intelligence must be searched for brand-related phrases and variants.

    However, keywords might appear in domain strings accidentally. The analysis is required to eliminate the process’s false positives.

    Two separate elements of a domain can reveal whether it is genuinely a danger:

    1. Analyze the domain string and provide a score based on how likely it is to be confused with legal brand usage.

    • Does it closely match keywords?
    • Can you tell whether a word is different?
    • Are there any letters, symbols, or capitalizations that can cause a user to become confused?

    2. Examine the content by visiting each of the domain’s pages.

    • Do you have any data?
    • Does it appear to be associated with a reputable brand?

    It’s not always easy to tell if two pieces of information are connected or not. To assess if a suspicious domain is a threat, marketing, legal, or other company operations may need to review the domain.

    A second set of considerations must be made when the domain is judged suspect:

    1. A thorough review of all of the domain’s material should be conducted in order to uncover any illicit or harmful activity. Web pages should be thoroughly inspected by security experts in search of any indications of malicious activity.
    2. Inspect the domain to see whether it has an MX Record. The domain’s mail servers are included in this record. If a domain has an MX record, it may send an email even if it does not have any content. BEC, email phishing, and spam operations can take advantage of this. MX records may be used to detect whether a domain is malicious.

    Mitigation

    It is imperative that a domain be entirely eliminated as a danger once it has been identified as a threat. Domain security teams should implement a thorough domain mitigation approach that involves removing the danger and employing indicators to prevent internal users from accessing it.

    Attempts to visit look-alike domains by enterprise users and systems should be detected and prevented by incorporating them into internal intelligence and workflow procedures.

    Automated interfaces with intelligence and security tools and controls are ideal here. Security restrictions are less likely to have an adverse effect on users as a result of this mitigating strategy. On the other hand, this approach doesn’t deal with the danger posed by users who bypass security safeguards. In addition, this method fails to address the dangers of brand and customer fraud.

    Taking the malicious domain offline is the only surefire way to reduce the risk posed by a lookalike domain. Security teams must have enough proof to immediately shut down a domain that is being used for nefarious purposes. A potentially harmful domain should be watched until proof of malicious material or activity can be found to warrant the removal of the site if at first no evidence is present when the domain is initially discovered.

    Security teams can take down a domain if they have gathered enough evidence to support its removal. Domain registries, in general, have a wide range of anti-abuse authorities. 

    When presented with evidence, they will often delete names that have been abused for:

    • Hosting phishing sites
    • Hosting malware
    • Botnet command and control
    • Disseminating material that encourages the exploitation of children

    In these cases, the registry can clearly see that abuse is occurring. However, in other cases, the domain may be involved in fraud that the registration does not consider to be abusive. Takedowns are not necessary unless there is a court order or a request from police enforcement for them to be removed.

    Legal action isn’t the best approach to deal with these threats, unfortunately. A domain shutdown by legal action is extremely time-consuming and expensive, regardless of whether it is pursued through litigation or arbitration. Domain risks can’t be mitigated using this method. It’s a last resort, after all.
