What is a mismatched URL?
A mismatched URL occurs when the visible link text in a message (like an email or a web page) doesn't match the hyperlink destination. Phishers use this technique to deceive users into thinking they're clicking on a legitimate link while directed to a malicious website.
A mismatched URL occurs when the visible link text in a message (like an email or a web page) doesn't match the hyperlink destination. Phishers use this technique to deceive users into thinking they're clicking on a legitimate link while directed to a malicious website.
Examples:
Visible Link vs. Actual Link:
Visible Text: www.yourbank.com
Actual Hyperlink: www.yourb4nk.com
in this example, the number "4" replaces the letter "a." The link looks legitimate at a glance, but it directs to a different, potentially malicious site.
Using Subdomains to Deceive:
Visible Text: www.yourbank.com
Actual Hyperlink: www.yourbank.com.phishing.com
In this case, "yourbank.com" appears as a subdomain of "phishing.com," the main domain. Unsuspecting users might believe they're going to "yourbank.com," but they're not.
How to Detect a Mismatched URL:
Hover Over the Link: Before clicking on any link, hover your mouse pointer over it. Most browsers and email clients will display the URL destination in the status bar or as a tooltip. This allows you to see where the link goes.
Check for Subtle Differences: Many phishers use URLs with slight, easy-to-miss misspellings or substitutions. Always double-check URLs for any anomalies.
Check the Protocol: Ensure the link starts with "https://" (the "s" stands for secure) rather than just "http://." The presence of "https://" doesn't guarantee a site's legitimacy. Still, it does indicate that the site encrypts data, offering a layer of protection.
Manually Type URLs: When in doubt, manually type the URL into your browser's address bar rather than clicking the link. This ensures you're going to a legitimate site, not a malicious one.
Why Phishers Use Mismatched URLs:
To Deceive Users: The main goal is deception. Users who believe they're on a trusted site are more likely to provide sensitive information.
To Bypass Security Measures: Some security tools check for known malicious URLs. Phishers can evade these measures by creating a new, slightly altered URL.
To Create Urgency: Phishing attempts often contain urgent messages, prompting quick action. When users act hastily, they're less likely to notice the mismatch.
Mismatched URLs are a classic trick in the phisher's playbook. Always be cautious and take a few extra seconds to verify any link before clicking, especially in unsolicited messages or emails. Being vigilant and knowing what to look for can protect you from many online threats.
