Smishing

Messages that seem harmless, but aren't always.

Smishing, what is it and how do you avoid it?

It's a type of scam where cybercriminals send text messages that appear legitimate. They impersonate banks, companies, or known services to get the victim to click a link or share personal information.

The goal is to gain access to confidential data in order to commit fraud. And the more convincing the message, the greater the risk of falling into the trap.

How does smishing work?

1. You receive a suspicious message

The SMS mentions an issue with an account, an unauthorised charge, or a pending action. The tone is usually urgent and designed to prompt a quick reaction.

2. The message contains a fraudulent link

That link redirects to a site that mimics the official website of a company or organisation. At first glance, it looks real.

3. It requests personal or banking information

On the fake website, you're asked to enter passwords, card numbers, or other sensitive data. By doing so, you're handing this information directly to the scammer.

Warning signs of a smishing attempt

  • The message creates a sense of urgency: “update your details”, “avoid account suspension”, etc.
  • The sender seems familiar but may have subtle differences in the number or name. It’s common for scammers to use the same name as the company or institution they’re impersonating.
  • The link doesn’t lead to a secure page: there's no https://.
  • It asks for information that no legitimate entity would ever request through any channel.

Tips to prevent smishing

  • Be suspicious of messages that create urgency or offer unexpected rewards.
  • Never share access codes or personal data with any entity via SMS, email, or phone call.
  • Avoid clicking on links in unverified messages.
  • Always check the full URL of any link, especially if it’s shortened.
  • Stay informed about the most common fraud techniques to reduce your risk.
