"A Computer Scientist Explains How QR Codes Work and What Makes Them Dangerous"

There are security risks associated with QR codes, which are graphical representations of digital data that can be printed and later scanned by a smartphone or other device. In December 2023, the Federal Trade Commission (FTC) gave another warning about the dangers of scanning a code from an unknown source. Scott Ruoti, assistant professor of computer science at the University of Tennessee, explains why visiting URLs stored in QR codes can be dangerous in various ways. The URL of a QR code may direct a user to a phishing website designed to trick them into entering their username or password for another website. The URL could direct the user to a legitimate website and trick that website into performing a malicious action, such as granting an attacker access to their account. Although such an attack requires there to be a vulnerability in the website, such flaws are common. This article continues to discuss the different ways in which QR codes threaten security.
