In a world where people scan QR codes without a second thought, attackers have found a simple way to exploit this habit. Behind an innocent looking code, there can be a malicious link that leads to a fake website, a dangerous download, or an attempt to steal personal information.
Why QR codes are risky
• You cannot see the destination before scanning
• Attackers can place a sticker over a real code and redirect to a malicious link
• Most users scan automatically without checking the source
• Many devices do not have tools that scan and block malicious links in real time
How it looks in real life
• Restaurant menus that redirect to a fake site
• Parking payment codes that lead to a fraudulent payment page
• Public signs with replaced stickers that send users to an attack page
• Messages with QR codes offering prizes or fake delivery updates
How to protect yourself
• Scan only QR codes from trusted sources
• Check that the code is not a sticker placed on top of another code
• Use phishing protection tools that analyze links before opening
• Never enter personal information after scanning unless you verify the page
