What is SMS Spoofing and How to Prevent it

In today’s digital era, mobile communication plays a crucial role in our daily lives. However, this convenience comes with risks, one of which is SMS spoofing. SMS spoofing is a technique used by cybercriminals to send messages that appear to come from a trusted source but are actually from a different sender. This article will explain what SMS spoofing is, how it works, the different types, how to prevent it, and what steps to take if you suspect fraudulent activity on your Groww account.

How Does SMS Spoofing Work?

SMS spoofing works by manipulating the sender information displayed on a recipient’s phone. Cybercriminals use software or services that allow them to change the alphanumeric sender ID, making the message appear to come from a legitimate source, such as a bank or a trusted company. This deceptive tactic is often used to:

• Phishing: Trick recipients into revealing sensitive information such as passwords, credit card details, or personal identification numbers.
• Fraudulent Transactions: Mislead recipients into authorizing fraudulent transactions.
• Spreading Malware: Send malicious links that, when clicked, download malware onto the recipient’s device.

How to Prevent SMS Spoofing

1. Verify the Sender:
   • Check Details: Always verify the sender’s information before responding to any SMS. Look for discrepancies in the sender ID or message content.
