Phishing links are the entry point for the majority of account compromises, malware infections, and identity theft cases. The good news is that most phishing URLs have detectable red flags — if you know what to look for. Here’s how to evaluate any link before you click it.

Check the Domain First, Not the Link Text

The most important thing to understand about phishing links is that the visible text of a link tells you nothing. A link can display “paypal.com” while pointing to “paypa1.com/login.” Always check the actual destination URL, not the text.

On desktop: hover over the link and look at the URL displayed in the bottom-left status bar of your browser. On mobile: long-press the link — most apps show a preview of the destination URL.

Spot Domain Spoofing Techniques

Phishers use several tricks to make malicious domains look legitimate:

• Typosquatting — registering domains with common typos: “paypa1.com”, “arnazon.com”, “gooogle.com”
• Subdomain spoofing — putting the real brand name as a subdomain: “paypal.com.evil-domain.com” — the actual domain is “evil-domain.com”, not “paypal.com”
• Homograph attacks — using visually similar characters from other alphabets: using a Cyrillic “а” (which looks identical to a Latin “a”) in a domain name
• Hyphen tricks — “pay-pal.com” or “paypal-secure.com”
• Extra words added — “paypal-login-verification.com”, “amazon-account-update.net”

The rule: look at the root domain (the part just before the TLD: .com, .net, .org). Everything to the left is a subdomain; everything to the right of .com is a different TLD. The root domain is the only part that matters for legitimacy.

Suspicious URL Structures

Beyond the domain itself, URL structure reveals intent:

• Unusually long URLs with random strings — legitimate sites use clean, readable URLs; attackers use obfuscated strings to hide malicious parameters
• IP addresses instead of domain names — links pointing to http://192.168.1.1/login instead of a named domain
• HTTP instead of HTTPS for login pages — any legitimate site asking for credentials uses HTTPS
• Shortened URLs — bit.ly and similar services hide the destination; expand them first using a URL expander tool
• Unusual top-level domains — .xyz, .top, .click, .info on a financial or institutional-looking site is a red flag (though not conclusive)

Context Clues in the Message Itself

The link doesn’t arrive in isolation. Evaluate the surrounding context:

• Urgency and threats — “Your account will be suspended in 24 hours” is a manipulation technique, not a legitimate business practice
• Unsolicited contact — Did you initiate this interaction? Legitimate companies don’t send unexpected login prompts
• Mismatched sender — The display name says “PayPal Security” but the actual email address is “[email protected]”
• Grammar and formatting — Not all phishing is poorly written, but awkward phrasing or formatting inconsistencies remain common

Use a Scanner for Links You’re Not Sure About

When you’ve got a link that feels suspicious but you can’t immediately identify why, the Phishing Link Scanner analyzes the URL for phishing indicators — domain patterns, structural red flags, and context signals — giving you a clear verdict and a breakdown of any red flags found. For real-time threat intelligence, also check the link on VirusTotal.com, which queries 70+ security engines.

Building the Habit

The goal isn’t to become suspicious of every link — it’s to build a quick evaluation habit for unexpected or high-stakes links. Routine links from services you regularly use in expected contexts (your bank’s app sending you a notification you initiated) are low risk. Unexpected links arriving via email or text claiming urgent action is needed deserve scrutiny before you click.
