In this digital age, there are many new threats to our digital security. One of the most insidious forms of cyberattack is smishing.

In this blog article, we’ll explore what smishing is, how it works, the different types of smishing attacks, common smishing scams, how to prevent smishing attacks and the tools you can use to defend against smishing.

What is Smishing?

Smishing is a type of malicious attack that uses SMS (Short Message Service) text messages to try to steal your personal information or money. It’s a form of phishing, but instead of using email messages, it uses SMS text messages to deliver the malicious payload.

The messages usually appear to come from a legitimate source or person, such as your bank or a friend, and they often include a link to a malicious website or a malicious file to download.

Smishing is a form of social engineering, meaning attackers use psychological tactics to manipulate people into giving up sensitive information or money. It’s a sophisticated attack, and it’s becoming more and more common as people become more reliant on their mobile phones.

How Does Smishing Work?

Smishing works by sending a text message that appears to come from a legitimate source or person. The message will contain a link or a malicious file to download. When you click on the link, it will take you to a malicious website, or it will download a malicious file. A malicious website or file is designed to steal your personal information or money.

The attackers may also use social engineering tactics to try to convince you to give them your personal information or money. For example, they may say that your bank account needs to be verified or that you need to pay a fee to renew your subscription. They may also use scare tactics to make you think that you’ve been hacked, or that your account has been compromised.
