What is smishing? How to spot and avoid an attack

Cell phones and mobile devices make connecting with friends and family easy—but they can also make you available for malicious interactions with scammers. 

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.

	Channel	Content	Example
Smishing	SMS or text messages	Requests for info or  malicious links	A text with a link to confirm a  supposed delivery
Phishing	Email	Requests for info or malicious links	An email from your bank with a link to reset your password
Vishing	Phone calls, automated recordings, or voicemails	Threats or requests for info, support, or money	A caller poses as the IRS threatening legal action unless you pay unpaid taxes

How does smishing 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.
