Beware the square: how to spot malicious QR codes

If you’re scanning a QR code that’s supposed to take you to a legitimate website, how can you be sure that it’s actually taking you to a safe place? Well, if you’re using the QR code-scanning feature built into your default camera app or many other run-of-the-mill scanning apps, the unfortunate reality is that you can’t be sure. The sole goal of such features is simply to unscramble the QR code and surface a link for you to click on. Fortunately, Sophos created a free app that will scan QR codes and tell you if the site they’re sending you to is safe or not. It’s called Sophos Mobile Security, and is available for Android and for iPhone.
