8 Ways to Prevent Typosquatting Attacks Targeting Your Business

BOLSTER has also paired this article with a FREE resource, 'Leveraging AI to Stop Typosquatting Attacks.'

Typosquatting is a tactic nearly as old as the Internet itself, perhaps in part because it’s so easy to pull off. All the attacker needs to do is purchase a domain and wait. Provided their URL is close enough to that of an established brand, someone will eventually stumble upon their trap, courtesy of a mistyped URL — a ‘B’ instead of a ‘V,’ perhaps, or .co instead of .com.

This particular kind of URL spoofing is almost always malicious. In some cases, it’s part of a phishing campaign, intended to compromise user accounts and other data. Other times, the website itself hosts a malicious phishing payload such as ransomware. The attacker might even be a plagiarist looking to sell counterfeit products.

If a threat actor creates a convincing enough typosquatting attack, imitating your website, they can cause tremendous damage to your brand as visitors may believe that you’re genuinely associated with malicious or poor-quality content. To make matters worse, a manual website takedown request is often so time-consuming that by the time it’s finally fulfilled, the damage has already been done.

That’s the bad news. The good news is that it’s possible to prevent typosquatting and protect your customers and business partners from fraudulent websites. It starts with understanding what typosquatting is and how it works.

The Anatomy of a Typosquatting Attack

Typosquatting has a great deal in common with other phishing attacks, particularly if it’s intended as part of a larger brandjacking campaign. A typosquatter typically creates a website or URL that seems just legitimate enough to momentarily fool a visitor.

Where typosquatting differs from phishing is that in a vacuum, it’s largely passive, reliant entirely on the user to enter and visit an incorrect URL.

Typosquatted URLs typically take one of the following forms:

  • Common misspelling of the original’s name or website.
  • Alternative spelling of the original website.
  • Different top-level domain from the original. This may also involve the use of country code top-level domains.
  • Identical to the original save for the presence or absence of a hyphen or period — this may also be referred to as a doppelganger domain.
  • Singular rather than plural (or plural rather than singular).

Some of the largest businesses and brands in the world have been targeted by typosquatting attacks, including Google (goggle), AirFrance (Arifrance), Equifax (Equifacks), and Microsoft (MikeRoweSoft). Celebrities and politicians, too, must frequently deal with typosquatters.

The Different Types of Typosquatting

Typosquat domains are usually created with one or more of the following objectives in mind.

It’s important to know the different ways typosquatting attacks can target your business

Distribution of ransomware or malware

Rather than featuring any content, a typosquat domain may simply perform a drive-by download of ransomware, adware, or spyware.


The threat actor’s spoof site is intended to imitate the genuine article. This is often done with the purpose of identity theft or business credential theft. Even a single stolen password can, without the necessary checks and balances, take down an entire organization.

Financial fraud is another common reason for brandjacking, as the attacker fools visitors into either purchasing counterfeits or buying products they’ll never see.

Revenue generation

Typosquatting may exclusively exist for revenue generation purposes. Generally, they’ll achieve this in one of two ways—either through ad impressions, or via phony affiliate links.

Traffic manipulation

A typosquatter might use their site to drive traffic to competitors and away from the brand in question. Occasionally, as was the case with John Zuccarini, this traffic redirection has a far more malicious goal in mind.


The typosquatting site wasn’t necessarily created with malicious intent, but instead mocks or otherwise derides the brand. This can still cause significant reputational damage.


Some particularly clever typosquatters are well aware that larger businesses often opt to make strategic domain purchases. Viewing this as a quick and easy payday, they purchase a domain with the intent of selling it to the related business.

Out of Network, Out of Control: How to Reign In Typosquatting

Digital transformation has fundamentally disrupted cybersecurity. It’s pushed technology products into cloud-based, self-service consumption models, shattering the security perimeter in the process. This trend is only further exacerbated by the shift to distributed work and the increasing prominence of personal devices in the workplace.

To address this new paradigm, organizations must embrace a digital risk protection strategy.

The external attack surface represented by these websites is massive. It’s impossible to contend with manually — businesses must take a different approach, one that begins with the right phishing and scam detection and remediation service.

1. Awareness and education

As is often the case with cybercriminals, typosquatting relies largely on the ignorance and carelessness of their targets. As such, a little education can go a long way toward bringing their efforts crashing down. Coach your employees on the importance of being mindful when browsing the web, including double-checking every URL they enter—or just using search engines for navigation, instead.

This education should be part of general security awareness training, which is equally crucial to avoiding social engineering attacks.

2. Trademark registration

One potential avenue for combatting typosquatters is to register your website under a trademark. That way, if all else fails, you can take the legal route and file a Uniform Rapid Suspension (URS) lawsuit against the typosquatter via the World Intellectual Property Organization. This is particularly effective against anyone seeking to blackmail your organization with a phony domain name.

3. Strategic domain ownership

A diligent company could attempt to purchase every variation of each domain it owns. Unfortunately, this approach is so cost-prohibitive that it’s nearly impossible. Even a simple, six-character brand name like Google has tens of thousands of potential variations; purchasing every single one could cost hundreds of thousands or even millions per year.

What you must do instead is make your purchases strategically. Determine which domains are the likeliest candidates for typosquatting and acquire those first. Ideally, your organization will be able to tap the expertise of one of its security vendors for help in that regard.

4. Deep learning

The web is impossible to monitor with human eyes alone. What your organization needs is AI-driven real time detection. Once you enter your domain names and business information, that should be all the system needs to go to work continuously analyzing the internet, dark web, app stores, and every other digitally accessible ecosystem for signs of impersonation and fraud.

It’s also imperative that you choose a platform with fast detection and a low false positive rate — if your organization must babysit the platform, that defeats the purpose of automation.

5. Automated, zero-touch takedowns

Detection through continuous monitoring is only half the battle. Remediation is where time is truly lost, which is why your organization must seek a platform that automates and streamlines the process. Seek a vendor that maintains relationships with registrars and hosting providers worldwide, one whose solution leverages API integrations to bring down potentially fraudulent sites before they’re even live.

6. Advanced real-time monitoring

Monitoring aside, a phishing and scam detection solution should also be capable of contextualizing potential threats. For instance, if a typosquat domain has a Mail Exchange (MX) record, that may be an indicator that it will be used to launch a phishing or business email compromise (BEC) campaign. Traditional tools and processes cannot effectively prevent a threat of this nature, as they lack a means of applying contextual analysis at scale.

7. Rich threat intelligence

Threat actors do their best work in the shadows, away from the prying eyes of security professionals. Find a solution capable of denying them this — one with a robust monitoring dashboard that grants fully detailed, actionable visibility into each suspicious domain and asset it detects. A high level of customization is also a must, along with the freedom to display threat intel in a range of different formats and based on a wide selection of metrics, including:

  • Grouping look-alike domains, sites, apps, and platforms by geographic location, top level domain, IP address, etc.
  • Domain usage data
  • Registrant information
  • Recommended actions

A More Intelligent Way to Prevent Typosquatting
