In addition to stealing money, using this technique it would also be possible access certain sensitive data of the victims stored on their devices, which would be shared with attackers at the time of scanning the code.
For that reason, it is recommended be careful with those QR codes that are scanned with the mobile, always reviewing aspects that may reveal a fraudulent code, such as the absence of HTTPS protocol in the link to which it directs, or the use of a suspicious url. Also, it may be a good idea to use apps like Google Lens when scanning the codes, since the Google tool shows a link preview to which the QR code directs us, instead of accessing it without first asking the user.
