What Is Typosquatting? How Attackers Exploit Misspelled Domains
Typosquatting is one of the most common techniques used in phishing attacks and brand impersonation campaigns. Attackers register domain names that closely resemble legitimate websites, hoping users will visit them by mistake or trust them without noticing small spelling differences.
A typosquatting domain may differ from a legitimate website by only a single character. At first glance, the fake domain often appears identical to the real one. This makes typosquatting especially effective on mobile devices, where URLs are harder to inspect.
In this guide, you'll learn how typosquatting works, why attackers use it, common typosquatting techniques, real-world examples, and how to identify suspicious domains before they cause harm.

What Is Typosquatting?
Typosquatting, sometimes called URL hijacking, is the practice of registering domain names that are intentionally similar to legitimate websites.
The goal is to capture traffic from users who:
- Make typing mistakes
- Fail to inspect URLs carefully
- Click phishing links
- Trust familiar-looking domains
- Use mobile devices where URLs are truncated
Many typosquatting domains are used for phishing attacks, credential theft, malware distribution, advertising fraud, or brand abuse.
How Typosquatting Works
Step 1. A Popular Brand Is Selected
Attackers target well-known companies because users already trust them.
Common targets include:
- Amazon
- PayPal
- Microsoft
- Apple
- DHL
- Netflix
Step 2. A Similar Domain Is Registered
The attacker registers a lookalike domain containing a subtle variation.
Step 3. Traffic Is Directed to the Domain
Victims arrive through phishing emails, SMS messages, QR codes, advertisements, or typing errors.
Step 4. The Attack Occurs
The victim may be shown a phishing page, malware download, fake login portal, or fraudulent payment page.
Why Attackers Use Typosquatting
Typosquatting is attractive because it exploits human behavior rather than technical vulnerabilities.
Benefits for attackers include:
- Low registration costs
- High success rates
- Brand trust abuse
- Phishing opportunities
- Credential theft
- Advertising fraud

Typosquatting vs Homograph Attacks
| Typosquatting | Homograph Attack |
|---|---|
| Uses spelling changes | Uses visually similar Unicode characters |
| Easy to spot when inspected | Can appear identical |
| Examples: paipal.com | Examples: Unicode lookalikes |
Although related, these attacks are technically different.
How To Detect Typosquatting Domains
- Inspect domains carefully.
- Check spelling character by character.
- Verify brand ownership.
- Inspect domain age.
- Review redirects.
- Look for added keywords.
- Analyze suspicious URLs before opening them.
2check.click can identify brand impersonation patterns, lookalike domains, suspicious redirects, and other phishing indicators associated with typosquatting attacks.
Why Domain Age Matters
Many phishing domains are newly registered shortly before being used in attacks.
A recently created domain is not automatically malicious, but when combined with typosquatting indicators it becomes a strong warning sign.
Business Risks
Typosquatting attacks affect both organizations and consumers.
Potential consequences include:
- Credential theft
- Financial fraud
- Business email compromise
- Customer trust erosion
- Brand abuse
- Malware distribution
Typosquatting Prevention Checklist
- Inspect URLs carefully.
- Use password managers that verify domains.
- Enable MFA.
- Avoid clicking unexpected links.
- Verify brands independently.
- Analyze suspicious domains before visiting them.
