What is smishing?

Smishing is a type of phishing cybersecurity attack that uses deceptive text messages to trick recipients into providing personal information or clicking malicious links.

It’s called “smishing” because it combines the terms “phishing” and SMS (Short Messaging Service). Phishing is traditionally a social engineering attack over email, but smishing takes place over text messaging channels.

Scammers use smishing to perpetrate identity theft and fraud or even to spread different types of malware. Shielding yourself against smishing attacks involves staying vigilant, understanding the signs of suspicious phishing text messages, and learning to protect your mobile security. 

Smishing vs. phishing vs. vishing

Phishing, smishing, and vishing are all tactics for stealing personal information—the difference lies in the form of their delivery. 

Vishing and smishing are types of phishing.

Phishing is a social engineering tactic used by scammers and cybercriminals. It’s often carried out via fake emails pretending to be from trusted sources. Phishing attacks accounted for 36% of all data breaches in the US in 2023.

Smishing, or SMS phishing, involves sending scammy, fraudulent, or malicious text messages hoping to get someone to reply or click a link.

Vishing, or voice phishing, is when scammers impersonate professionals or other trusted sources over the phone to trick victims into revealing sensitive data or transferring money or digital currency.

How does it work?

Cybercriminals use a combination of malware, malicious links, text threats, and social engineering tactics (like fear-inducing language and manipulation) to carry out smishing attacks. Here are the usual steps of a smishing attack:

1. A scammer sends a text message using social engineering tactics to trick you into believing the message is legitimate.
2. You click an infected link or provide personal information.
3. The scammer uses your information to carry out further attacks, commit fraud, or even sell the stolen data on the dark web.

5 types of smishing attacks 

Smishing text messages can come in many forms because hackers like to customize their messages to fit their targets. Keep these different kinds of smishing texts on your radar to help ensure the Cyber Safety of your smartphones and tablets.

1. Delivery notification and package-tracking smishing

Package delivery scams are among the most common types of smishing attacks, especially during holidays or major sales events. You might receive a FedEx, UPS, or USPS scam text notifying you about a delivery snag or requesting an update on shipping details. The text is a scam, aiming to trick you into clicking a harmful link or divulging personal information.

2. Financial services smishing scams

Financial services smishing scams take advantage of the fact that almost everyone uses banks and credit card companies to manage their finances. These smishing messages pose as legitimate banking institutions to get you to volunteer sensitive data like your Social Security number, address, phone number, password, email, and more. Smishers often send fraud alerts, warning targets about suspicious activity on their account, prompting them to click a link or call a phone number, both of which are malicious.

Some IRS-related scams to watch out for are messages promising tax credits or help with setting up an online IRS account. The IRS has reported an increase in smishing attacks, so keep that in mind if you receive a text message supposedly from the IRS. And remember that the IRS will never text you.

3. Confirmation smishing scams

A confirmation smishing scam uses fake confirmation requests to get you to expose sensitive information. This could be for an online order, an upcoming appointment, or an invoice for business owners. The smishing text may contain a link directing you to a site that asks you to input login credentials or other sensitive data to verify your appointment or purchase.

4. Customer support smishing scams

Customer support smishing scams send smishing texts posing as any company a person may trust—not just banks or credit card companies. They may pose as a representative from an online business or a retailer notifying you of an issue with your account. They’ll provide instructions to solve the issue, which may include directing you to a fake site infected with spyware. 

5. Gift or giveaway smishing scams

This type of smishing attack offers you a free gift or advertises a fake contest giveaway, trying to get you to click a malicious link to claim your prize. If you tap the link and end up on a website, your “gift” may be your own device infected with malware.

Smishing attack warning signs

Use these smishing attack warning signs to help determine if you’re dealing with smishing spam texts on your mobile device:

• Suspicious phone numbers: Smishing messages often come from numbers that don’t follow the typical 10-digit layout or use a series of the same number.
• Misspelled words or grammatical errors: Reputable businesses ensure their communications are free of typos and grammatical errors before sending them to customers. These careless mistakes are red flags and often signs of a scam.
• Links and files from unknown numbers: Phishing through text messages often includes deceptive links with unusual URLs that take you to an unsafe website.
• Urgent requests: Scammers frequently employ urgency to frighten their victims. However, genuine companies give ample notice about issues, so delete these messages or verify them with the supposed sender through an official channel.
• Money requests: Messages urging online money transfers are likely scams aiming to drain your funds.
• Prize notifications: Receiving prize alerts for contests you didn’t enter is a red flag; steer clear of engaging or clicking any embedded links.

How to avoid smishing scams

 Your cell phone is likely one of your most used and trusted devices. Avoid potential smishing scams with the help of these cybersecurity tips:

• Do not send personal information via text: Never give out personal details, such as passwords, credit card numbers, addresses, or emails via text.
• Inspect new phone numbers: Odd phone numbers may indicate a smishing attempt. Be careful of international numbers or those that don’t follow the typical format.
• Avoid clicking suspicious links or files: The core of a smishing attack is often a malicious link. Avoid clicking these links at all costs. Also, if you can tell a text is fake when you receive it, delete it immediately.
• Contact the business directly: Scammers commonly impersonate valid businesses or banks. If a text seems questionable, contact the institution directly to verify it.
• Never respond: One of the best ways to avoid future smishing attempts is to not engage. Replying to a smishing text confirms that your number is active and may lead to further attacks.
• Use two-factor authentication: Even if you get tricked and your password gets compromised, two-factor authentication adds an extra protective layer. For example, biometric technology uses a fingerprint or facial recognition to verify your identity.
• Download antivirus software: Downloading trusted antivirus software like Cyber1guard can help keep your device secure by protecting against hacking and blocking malware and other online threats before they infect your device.
