Why Are Shortened Links (bit.ly, t.ly) Dangerous? How to Preview Them Safely

September 20, 2026 · 1 min read

Link shortening services squeeze long addresses into a message. They have legitimate uses, but because they hide the real destination, they are also a favourite of scammers.

Why are they risky?

With a short link you can’t see the destination domain. You can’t tell whether t.ly/ab12 leads to a bank page or a fake phishing site until you tap it. Some attacks start with the tap alone: a malicious file is downloaded or a form page opens.

Before you tap a link

1. Check the sender: is it from a number you don’t know?
2. Was it expected? Don’t trust a “your parcel” message if you aren’t waiting for one.
3. Watch the domain: extensions like .xyz, .top, .click and look-alike spellings of brands are suspicious.
4. Use a preview: you can see a link’s redirect chain and page title without opening it on your phone.

Safe preview in HiSMS

When you long-press a link in HiSMS, you get a “Safe preview” option. The link is opened through the server, not your phone, so the page content never reaches your device. You see the redirect steps and page title. The feature is optional and runs only when you ask for it.

Block suspicious link patterns

With rules such as t.ly/* or *.xyz you can automatically quarantine every message containing links from those services.

If you already tapped

• Don’t enter any information; close the page.
• If something was downloaded, don’t open it; delete it.
• If you entered information, change the password of the account immediately and call your bank.

For link safety, try HiSMS.
