QR codes have become a staple of modern life, offering a quick and convenient way to access information, make payments, and share data. But this convenience has also made them a target for cybercriminals. A disturbing trend is emerging malicious QR codes are increasingly being used in phishing attacks, and the numbers are rising.
Recent reports indicate that a significant percentage – as high as 8% – of phishing attacks now leverage malicious QR codes, a stark reminder that even seemingly innocuous technologies can be weaponized.
Attackers replace legitimate QR codes with malicious ones, often in plain sight. These malicious codes can be found in various locations:

When an unsuspecting user scans the malicious code, user can be redirected to a phishing website designed to steal their login credentials, personal information, or even financial details. In some cases, the QR code might trigger a direct download of malware onto the user’s device.
