We make use of cell phones to do almost everything we do today, be it checking up on our loved ones or shopping for new stuff. However, this comfort comes at a cost, for these smartphones, as smart as they claim to be, are vulnerable to a host of cyberattacks that can put our personal and professional details at risk. One such threat is smishing.
For the unversed, smishing is when scammers make use of text messages to trick you into revealing sensitive information or making money transfers. They do so by using disposable numbers to send CTA messages, which, if acted upon, can give the attacker access to your personal information, financial accounts, or even your contact list.
However, there are various ways to guard yourself against smishing attacks. You can always verify the senders, review your accounts, make certain you never click on suspicious links, or enable endpoint security software or mobile security software on your device.
In this blog, we will ponder the meaning of smishing and how it works to shed light on the sundry ways you can protect yourself from falling prey to it, one tactic at a time.
The meaning of smishing is derived from the amalgam of terms like SMS and phishing. Accordingly, smishing is a type of phishing attack where an attacker, with help from text messages or messaging apps, tricks people into disclosing sensitive details, downloading malware, or transferring money.
Contrary to traditional email-based phishing, smishing takes advantage of the trust and urgency people ascribe to text messages. The attackers often impersonate brands or trusted authorities to make their messages look genuine and evade detection. With smartphones used in huge numbers across the globe, smishing attacks are a real threat to all, both businesses and individuals alike.
