URL Security: How to Protect Yourself from Malicious Links
Learn to identify phishing, typosquatting, and other URL-based threats
Introduction
Every day, millions of people click on malicious links that lead to phishing sites, malware downloads, or credential theft. Understanding URL security is essential for protecting yourself online. This guide will teach you how to identify dangerous links and stay safe.
Types of URL Threats
Phishing
Fake websites that mimic legitimate ones to steal your credentials. Often sent via email or social media.
Typosquatting
Domains with common typos like 'googel.com' or 'amazom.com' that catch users who mistype URLs.
Homoglyph Attacks
Using similar-looking characters from different alphabets, like Cyrillic 'а' instead of Latin 'a'.
URL Shortener Abuse
Hiding malicious destinations behind shortened URLs like bit.ly or tinyurl.
Open Redirects
Exploiting legitimate sites' redirect features to send you to malicious destinations.
Warning Signs
Be especially cautious with URLs that:
- Come from unexpected emails or messages
- Create urgency ('Your account will be deleted!')
- Ask you to 'verify' or 'confirm' account details
- Have unusual domain extensions (.xyz, .top, etc.)
- Contain IP addresses instead of domain names
How to Recognize Suspicious URLs
- Check the domain carefully - look for misspellings and extra characters
- Hover over links before clicking to see the actual URL
- Be wary of URLs with many subdomains (login.secure.bank.evil.com)
- Look for HTTPS, but remember attackers can use it too
- Be suspicious of shortened URLs from unknown sources
- Check if the domain matches the expected organization
Protection Tips
Use a URL checker
Always verify suspicious links before clicking. LinkPreview can help you analyze any URL.
Enable 2FA
Even if you fall for phishing, two-factor authentication can save your account.
Keep software updated
Browser security updates protect against many URL-based attacks.
Use a password manager
They won't auto-fill on phishing sites because the domain doesn't match.
Check SSL certificates
Click the padlock icon to verify the site's identity.
