It has become a sad reality of modern life that personal information you have innocently provided to the companies you do business with has been hacked and stolen. In this video, Adam Levin, cyber expert and author of Swiped, tells you what to do when your personal information has been compromised. It is crucial to note what information has been stolen in order to know what action to take. Of particular concern is when your Social Security number is part of the hack. In such an instance, Mr. Levin notes, it is important to take advantage of monitoring services that hacked companies offer. You can also freeze your credit to prevent new accounts from being opened. You can never have too much credit or identity monitoring.
