At this point, there have been so many data breaches, it’s more likely than not that some of your personal information has been compromised. “There are two kinds of consumers — those who know they’ve been breached, and those who don’t,” says Identity Theft Resource Center president and CEO Eva Velasquez. Many Americans are in the first camp. According to a Gallup poll, 27% of Americans say their credit card information has been stolen in the past year, and 11% say their computer or smartphone has been hacked. And the rest are scared: Almost 70% of Americans worry that hackers will steal their credit card numbers from retailers, and 62% worry that hackers will target their personal devices. It’s hard to say whether there has really been an increase in the number of data breaches, or we’ve just gotten better at detecting and reporting incidents, Velasquez says. Either way, the outdated magnetic stripe technology in the United States probably makes it too easy for hackers to run off with your credit card number. “Thieves are going to go where it’s easiest to steal,” Velasquez says. “We’ve got the most antiquated technology protecting the actual cards, and we’re the biggest issuer of those cards – we’re a treasure trove.” At MONEY, we’re tracking the major data breaches that may have exposed your personal information in recent months. Read on to see if you’ve been affected. If so, we’ll walk you through what you need to know about protecting yourself from identity theft.
