As QR codes grow in popularity with consumers, malicious codes are becoming much more common. These codes seem unassuming at first glance. Indeed, it is impossible to tell the difference between a legitimate QR code and one linked to harmful content with the naked eye. Even tech-savvy consumers have been having trouble discerning the true nature of some codes. The Websense ThreatSeeker Network, one of the world’s most advance web security networks from Websense Web Security, has found a number of new malicious QR codes that are being sent to people’s emails.
It is not uncommon for an email account o be flooded with messages containing links to malicious content. These messages are commonly referred to as spam. Websense has found a growing trend on the Internet that shows that spammers are beginning to use QR codes as a way to attack consumers.

This shortened URL can sometimes be confusing for consumers as they are unable to tell whether it is safe or not.
