What is a phishing text?

Phishing texts, also called smishing, are attacks from cybercriminals to trick someone through text messages. Often these texts are aimed at stealing personal information or scamming the recipient out of money by asking for information about credit cards or bank accounts. Some will encourage you to click on a malicious link that will download malware to your phone. The malware then goes to work to steal your personal information.

What to do if you get a spam text

Your best step is to block the text sender—don’t click any links!—and report the spam. Then, delete the text from your phone.

Silence is always the best policy. Never respond to spam texts, not even with “stop.” “Many times, spam texts are sent by programs that send them out en masse,” explains Burton Kelso, chief tech expert with Integral, a computer and laptop repair service. “When you respond to a text message, you’re letting the spammer know that your number is legitimate and that encourages the spammer to continue.” Then, your verified number could be sold to other text spamming companies, which is why “silence is always golden,” he says.

Report smishing to the authorities

Report spam messages to your cellular provider if you have AT&T, Verizon Wireless, T-Mobile, and Sprint. Simply copy and paste the text into a new message and send it to SPAM (7726). You will get a reply from the service asking for the number the text came from. Reply with the number and you’re done. “This won’t immediately stop the spam text, but it does help the community of smartphone users as far as identifying spam text numbers,” said Kelso.

You can also report the phishing text to the Federal Trade Commission and the Federal Communications Commission.

How to recognize spam texts when you see them

There are some key signs that a text message isn’t legit. First, is the company’s name is in the text? Legitimate brands will let you know up front when they’re reaching out to you.

Second, look at the link. Is the name of the company in the link? If so, it’s probably legit. If the email contains a shortened link (scammers often use a link), then don’t click it.

For example, lets you know that it will take you to a UPS tracking page.

On the other hand, the link gives you no clues, and could be from a scammer.

Scammers often use urgency to get you to take action without thinking. Catching you off-guard makes it easier to get you to click a link or answer with information.

Here’s an example of a smishing text that is vague, uses urgency tactics, and has a shortened link:

  • “You have a package that needs to be claimed ASAP.”

Other clues to look for include misspellings, bad grammar, slang, emojis, and typos. If the text doesn’t look professional, then it probably isn’t from a brand or company you trust.
