Types Of Smishing Attack – Signs And Prevention

Introduction

Ever received a text message that seemed a little “too good to be true?” Maybe it promised a prize or claimed your account needed urgent attention. That, my friend, could be a smishing attack—a sneaky form of cybercrime that's gaining momentum. So, what exactly is smishing? It’s a type of phishing that uses text messages to lure victims into revealing sensitive information. With the increasing use of mobile devices, smishing scams are becoming alarmingly common. Read on to learn how these scams work, the red flags to look out for, and how to keep your information safe.

What is Smishing?

Smishing combines "SMS" (short message service) with "phishing”, creating a devious strategy to trick unsuspecting users. Essentially, smishing is a type of phishing that uses text messages to manipulate people into sharing personal details - such as passwords, bank account numbers, or credit card details. These scams prey on trust and urgency, often masquerading as legitimate organisations like banks, government agencies, or even online retailers. The danger? Unlike emails, which often get filtered for spam or phishing attempts, text messages feel more personal and urgent - making it easier for fraudsters to access private information.

How Does Smishing Work?

A smishing attack typically starts with a simple yet suspicious text message. These messages may:

• Claim your bank account has been compromised
• Offer too-good-to-be-true discounts or prizes
• Warn you of a missed payment or urgent action required

The text will include a link or phone number urging immediate action. Clicking the link may lead to a fake website designed to collect your personal data, or it could install malware on your device. In some cases, the fraudster may ask you to reply with sensitive details directly.

Types of Smishing Attacks

There’s no one-size-fits-all approach for these cyber criminals. Let’s explore these common types of smishing attacks:

1. Banking Smishing
Fraudsters pose as your bank, claiming suspicious activity on your account. They might ask you to verify your identity or reset your PIN through a malicious link.
2. Prize or Lottery Scams
“You’ve won a jackpot!” These messages tempt victims with fake rewards, asking them to click a link or share personal details to claim their prize.
3. Delivery Notifications
With online shopping booming, delivery scams have skyrocketed. A smishing text might pretend to be from a courier, urging you to pay a delivery fee or confirm your address via a malicious link.
4. Tech Support Smishing
These scams claim your device has a security issue, prompting you to download an app or call a fake support number.
5. Subscription Renewal Scams
“Your subscription is about to expire. Renew now to avoid disruption!”

This type of scam usually attacks popular services like streaming platforms.

Signs to Detect a Smishing Attack

Spotting a smishing text message can be tricky, especially since these scams are designed to look genuine. However, paying attention to certain red flags can help you avoid falling victim. Here's a closer look at the key signs:

1. Urgency: Messages Demanding Immediate Action

Smishing texts often create a sense of panic or urgency to manipulate recipients into acting without thinking. For example, messages might say:
• “Your account has been locked. Click here to reactivate immediately.”
• “You need to verify your identity within 24 hours or your account will be deactivated.”
This tactic works because it taps into fear and the desire to fix a problem quickly. Legitimate organisations rarely use fear-based tactics to communicate.

2. Unfamiliar Senders: Numbers That Don’t Match Official Contacts

Many smishing scams come from unknown or suspicious-looking phone numbers. These might be random sequences, international numbers, or even spoofed numbers designed to appear legitimate.
For example, a message claiming to be from your bank might come from a personal-looking number (e.g., +91 9876543xxx) rather than the official short code used by your bank. Always double-check the sender's contact details against the organisation’s official communication channels.

3. Grammatical Errors: Professional Organisations Rarely Make Obvious Typos

While professional companies ensure their communications are free from typos and grammatical errors, smishing messages are often riddled with mistakes. This could include:
• Misspellings (e.g., “You’r acount has been locked.”)
• Incorrect punctuation or formatting
• Awkward phrasing or unprofessional language
These errors are a strong indicator that the message isn’t from a legitimate source.

4. Suspicious Links: Shortened or Obscure URLs

One of the hallmarks of a smishing attack is the inclusion of links, often shortened or disguised, to trick users into clicking. These URLs may lead to fake websites designed to steal personal information or install malware on your device.
For instance, a link like bit.ly/123xyz or a domain that resembles a real one (e.g., bank-secure-login.com instead of bank.com) is a major warning sign. Before clicking any link, hover over it (if your device allows) or verify it through a trusted source.

5. Requests for Personal Info: Legitimate Companies Don’t Ask for Sensitive Information via Text

A clear red flag is when a message asks for personal or financial details directly. Scammers may request information like:
• Bank account numbers
• Passwords
• Credit card details
• OTPs (One-Time Passwords)
Remember, reputable organisations, especially banks or government agencies, will never ask for sensitive information through text messages. If you receive such a request, contact the organisation directly through official channels to verify the claim.

Tips to Prevent Smishing Attacks

Protecting yourself from smishing doesn’t require advanced tech skills. Follow these simple tips to stay safe:

1. Think Before You Click

Never click on links in unsolicited text messages. If a message seems urgent, verify its legitimacy through official channels.

2. Avoid Sharing Personal Information

Legitimate companies won’t ask for sensitive data like passwords or PINs via text.

3. Enable Two-Factor Authentication (2FA)

An additional security layer for your account is necessary to strengthen it in the face of smishing attacks. Even if a smishing attack compromises your password, 2FA can block unauthorised access.

4. Keep Your Software Updated

Outdated operating systems and apps are easier targets for malware. Regular updates patch vulnerabilities.

5. Use Anti-Malware Tools

Install security apps to scan for malicious links or apps.

6. Block Suspicious Numbers

Most mobile devices let you block specific numbers. If you receive a smishing text, block the sender immediately.

7. Report Smishing Attempts

In India, you can forward suspicious messages to 1909 or report them to the National Cyber Crime Reporting Portal.
