How Phishing Links Work — and Why They Are Getting Harder to Spot

A link is just text. It takes fewer than fifty characters to build a URL that looks legitimate and points somewhere dangerous. Understanding the mechanics of phishing links removes much of their power.

How a phishing URL is constructed

A legitimate bank URL looks like this: https://www.crdb.co.tz/login

A phishing URL trying to imitate it might look like any of these: - https://crdb.co.tz.login.verify-account.com - https://crdb-co-tz.verification-portal.net - https://www.crdb.co-tz.info/secure/login

In each case, the fraudster controls a domain they registered — verify-account.com, verification-portal.net, co-tz.info — and places the bank's real name somewhere in the path or subdomain to create visual familiarity.

The redirect chain

Modern phishing attacks rarely send you directly to a fake login page. They use a chain of redirects: a first URL shortener that looks harmless, a second domain that performs a browser check, then the final destination page. This chain is designed to make automated scanning harder and to show different content to security researchers versus real victims.

HTTPS is not a guarantee of safety

A padlock icon in your browser means the connection is encrypted, not that the website is legitimate. Fraudsters routinely obtain valid SSL certificates for their fake domains. The padlock means your data is transmitted securely to the fraudster, not that you are safe.

URL shorteners and forwarding services

Short links — bit.ly, t.co, tinyurl — hide the destination until you click. In messaging contexts, fraudsters use them because the short link passes platform spam filters. Lindanix expands and analyses the full destination chain before returning a verdict, so you never need to click to find out where a link leads.

What makes a link safe versus suspected versus dangerous

Lindanix uses domain age, registration data, hosting reputation, link-in-path analysis, and content pattern matching to classify links. A domain registered three days ago serving a page with a password form and a bank logo is not safe by any reasonable standard. You should know that before you type a single character.
