Though a free gift card to Best Buy or Target sounds like a lucky break, never reply to an unsolicited text message that promises one. It’s a scam. The Better Business Bureau is advising people to not reply to any text messages from unknown senders or text messages that otherwise seem strange. These messages could contain malware leading to identity theft.

WALA FOX10 of Mobile, Alabama reported that the local Better Business Bureau is receiving up to 20 reports of text message scams each week. The station interviewed Stephanie Knight of the Mobile BBB who said that by clicking on the fraudulent messages “you are opening up a world of your information.” Knight also said if the sender is a 1-9 or 1-9-0 number, there’s a good chance the message is a scam.

The type of data that can be accessed from these scams includes social security numbers and bank information. One way to effectively protect yourself against identity theft is to place a freeze on your credit report. This notifies credit agencies, who won’t allow any use of your credit information without your consent.
