Stop Smishing Attacks: 5 Proven Cybersecurity Tips to Prevent Text Message Phishing

Your phone buzzes. A text, supposedly from your “bank,” urges you to click a link to secure your account. But is it really your bank? You pause—this feels off. I rarely get texts from my bank asking for things! That’s likely smishing (SMS phishing), a cyberattack surging in recent years. In 2024, nearly 1 in 3 phishing attacks targeted phones via text, with smishing scams spiking 22% in a single quarter. These fraudsters are cunning, but the good news is you can outsmart them. In this post, I’ll explain what smishing is, why it’s a threat, key warning signs, and simple steps to stay protected.

What Is Smishing, and Why Should You Care?

Smishing combines “SMS” and “phishing.” Cybercriminals send texts posing as trusted entities—banks, delivery services, or even your boss—to trick you into sharing sensitive information or clicking malicious links. One misstep can lead to stolen passwords, drained accounts, or malware infections.

Why is smishing so dangerous?

• It’s personal. Texts feel immediate and urgent, unlike emails.

• It’s deceptive. Scammers spoof numbers to mimic legitimate sources.

• It’s growing. Over 30% of phishing attacks now begin with a text, and 40% of mobile threats in 2024 were smishing-related.

Real-world example: fraudsters impersonating FedEx, texting users to “reschedule a delivery” via a malicious link. You click on the link, landing on a fake site that steals your credit card details.

Red Flags: How to Spot a Smishing Text

Smishing texts are often crafted to spark panic and prompt quick action. Stay sharp by watching for these warning signs:

• Urgent or threatening tone. “Your account is locked! Act now to avoid penalties.” Legitimate companies rarely demand instant responses.

• Suspicious links. Check the link text (but don’t click!). Shortened URLs (like bit.ly) or odd domains (e.g., “bank-security.xyz”) are major red flags.

• Unfamiliar sender numbers. A 10-digit number or strange area code is suspect. Scammers often spoof numbers, but businesses typically use shortcodes (e.g., 12345).

• Poor grammar or typos. Professional organizations proofread; scammers often skip this step.

• Requests for sensitive data. Banks never ask for passwords or PINs via text.

Pro tip: If a text seems questionable, trust your instincts. Scammers thrive on impulsive reactions.

5 Simple Steps to Prevent Smishing Attacks

You don’t need to be a cybersecurity expert to stay safe. Here’s how to secure your phone and foil smishing attempts:

1. Verify the Source Independently
   Ignore the text’s links or phone numbers. Visit the official website (e.g., your bank’s) or call the number on your credit card to confirm the message’s legitimacy.

2. Avoid Clicking Unknown Links
   A single click can install malware or lead to fake login pages. If you need to investigate a link, type it manually into a browser after verifying its source.

3. Enable Two-Factor Authentication (2FA)
   Activate 2FA on your accounts (banking, email, etc.). This extra layer of security stops scammers even if they steal your password.

4. Filter and Block Spam Texts

   • iPhone: Go to Settings > Messages > Filter Unknown Senders.

   • Android: Enable spam protection in Messages (check your device settings).

   • Report suspicious texts by forwarding them to 7726 (SPAM) to alert your carrier.

5. Stay Informed and Update Your Device
   Keep your phone’s software updated for the latest security patches. Follow cybersecurity resources (like this blog!) to learn about emerging scams. Apps like Truecaller can help identify questionable numbers.

What to Do If You Fall Victim

If you clicked a link or shared information, act quickly:

• Change passwords immediately for affected accounts. Use strong, unique passwords.

• Contact your bank or service provider to report fraud and freeze accounts if necessary.

• Monitor your accounts for unusual activity and review your credit report for unauthorized accounts.

• Report the scam. File a complaint at ftc.gov or ic3.gov to help authorities track and stop fraudsters.

Stay Ahead of the Game

Smishing is a rising threat, but you’re not defenseless. By recognizing warning signs, verifying sources, and securing your accounts, you can keep cybercriminals at bay. Share these tips with friends and family—scammers target everyone, and awareness is our strongest defense.
