I was checking out Dark Reading, a fabulous site for information security news, and today’s article by Ericka Chickowski, titled “QR Code Malware Picks Up Steam” caught my attention.
QR codes (Quick Response codes) are being used more and more by mobile marketers, and are a hacker’s dream for spreading malware. A QR code is a 2D barcode that can store data which can then be read by smart phone users. The data is an easy way to direct a user to a particular website with a simple scan of the QR code, but it could also just as easily be a link to a malicious website.
Wikipedia lists some of the risks associated with QR Codes:
Malicious QR codes combined with a permissive reader can put a computer’s contents and user’s privacy at risk. They are easily created and may be affixed over legitimate QR codes. On a smartphone, the reader’s many permissions may allow use of the camera, full internet access, read/write contact data, GPS, read browser history, read/write local storage, and global system changes.
