Shortened URLs: what they are and what precautions to take

Shortened URLs are normally used on social media, such as Twitter, and in short messages (especially SMS), mainly due to the limit on the number of characters in each message. Shortened URLs are web addresses with a reduced number of characters that represent a much longer web address, although they take visitors to the same page.

They are very practical, but at the same time, it is important to take precautions before opening them, because it's not immediately obvious what real website address they are concealing.

What should you do when you come across a shortened link?

• First and foremost, it's important to analyse the substance of the message containing it. In the case of alert, urgent or even threatening messages, it's probably a scam, meaning you should not click on it.
• To find out what website the link leads to, we recommend using a tool that reveals the original extended link, such as http://unshorten.it/
• Clicking on certain shortened URLs could take you to a login screen in an effort to try to steal your personal details and passwords. They could also prompt you to download files that could infect your device with malware.
• If the message with the shortened URL seems to have been sent by your bank, never click on the link. Directly type in your bank's website address in your browser or use the legitimate app. Never log into your bank from links that you get via email or messages.
• On social media or other channels, even if the messages come from an apparently reliable sender, be wary.

Remember that CaixaBank will never ask you for your personal details, username or password through any channel. If you need to access online banks or other services, always do so by typing in the address into your browser yourself or using Now, the official app.
