DigiKitWhen Are Shortened Links Risky?
What to watch for when a link-shortening service hides the real destination.
Summary
A shortened link stops you from seeing its real destination before you click. That makes clicking a shortened link from an unfamiliar source the same as trusting an unknown address.
Step by step
- Consider whether the sender is trustworthy.
- Use a link-preview tool to see the real destination.
- Stop if it asks for an unexpected login page.
- When you shorten your own links, mention the destination.
Why it matters
With a normal link, you can usually guess where it goes by hovering over it or glancing at the address. A shortened link takes that clue away. That's why scam messages lean on shorteners so much. A short link in a text that looks like a delivery notice, a bank alert or an unpaid fine can lead to a fake login page. The shortening service isn't the villain. The problem is that the destination is hidden.
Risks that aren't about security
Malicious use isn't the only issue with short links. If the service shuts down or deletes free links, a link you printed on a brochure, a business card or a slide years ago simply stops working. Some services log every click. That's handy analytics for whoever shared the link, but for the person clicking it can mean being tracked. And because the short link only points somewhere, its owner can change where it goes later on.
Common mistakes
- Trusting a link just because it came from someone you know. A hijacked account can send short links to everyone in its contact list.
- Typing a password without checking the page's address. The logo and colors can be identical. Only the address bar shows a one-letter difference in the domain.
- Relying on a free shortener for printed material. A short redirect on your own domain lasts much longer.
- Treating QR codes as something different. A QR code is also a link that hides its destination, and it deserves the same caution.
A realistic scenario
An employee gets a text saying their package couldn't be delivered, with a short link included. Before tapping it, she pastes the link into a preview tool and sees the destination looks nothing like the courier's domain. She deletes the message and checks for pending deliveries in the courier's own app. She also forwards a screenshot to the company's IT team the same day.
What to do if you already clicked
If you didn't enter anything on the page, closing the tab is usually enough. If you typed a password, change it right away, along with any other account that uses the same one, and turn on two-factor authentication where you can. If you entered card details, call your bank without delay. If it happened on a work device, tell your IT team. Reporting it early is the easiest way to limit the damage.
