What the suspicious link checker looks for
Most phishing and scam links rely on a trick in the address itself, because the address is the one thing a person can read before clicking. This checker reads the link the way a careful friend would. It finds the real domain (the part that decides who owns the site), compares it with brands that are often impersonated, and looks for the patterns attackers use to disguise where a link goes. Everything happens in your browser: the link is never uploaded, logged or opened.
The tricks it recognises
- Misleading subdomains. In
paypal.com.secure-login.examplethe owner issecure-login.example, not PayPal. Domains read from right to left. - Mistyped and swapped letters. Names like
paypa1(a one for an L) orrnicrosoft(r and n for m) are built to pass a quick glance. - Look-alike alphabets. Some letters from other alphabets are visually identical to Latin ones. Domains that mix alphabets are flagged.
- Hidden destinations. An
@sign, a link shortener or a redirect parameter can make a link start with one name and end somewhere else. - Raw IP addresses and odd ports. Real services use names.
- Direct downloads. A link that points straight at an installer or archive deserves more caution than a web page.
Why the questions matter
The same link can be fine or dangerous depending on context. A perfectly ordinary address in an unexpected message that asks you to sign in is a classic phishing setup, while the same address typed by you is much safer. The three questions adjust the advice to your situation, and a browser warning always outranks everything else on this page: if your browser says the site is dangerous or the certificate is wrong, stop.
What this tool cannot tell you
It cannot prove a website is safe or malicious. A brand-new scam domain with no obvious tricks will look clean, and a legitimate site can have an unusual address. It does not check blocklists, open the page or see the message around the link. Use it as a second pair of eyes, then confirm through a route you trust: type the real address yourself, open the official app or call a number printed on a card or the company's own website.
If you already clicked
Do not panic. If you only opened the page, close it. If you typed a password, change it immediately on the real site and anywhere you reused it, then turn on two-step verification. If you entered card details, call your bank. Our guide on what to do if you clicked a phishing link lists the steps in order.
