The convenience of QR codes (Quick Response codes) has made them a ubiquitous part of our daily lives. Whether you are ordering food at a restaurant, checking into a hotel, paying for parking, or scanning a product label, these black-and-white patterns are everywhere. However, this ease of use has opened a new door for cybercriminals.<\/p>\n

This lack of transparency is the primary “hook” that attackers exploit.
