QR codes are getting colorful, fancy, and dangerous

Help Net Security

QR codes are increasingly being stylized with colors and shapes, leading to new security risks. Researchers from Deakin University have identified that these visually appealing QR codes can be manipulated in 'quishing' attacks, where attackers trick users into scanning harmful codes. The assumption that QR codes are safe can make users more vulnerable to these scams. The study proposes a new method to detect compromised QR codes based on their structural analysis. This research emphasizes the need for users to remain cautious and critically evaluate QR codes, similar to how they approach links in emails or websites.
