What term describes the basic QR code's vulnerability where a malicious sticker can be placed over a legitimate one?
Answer
attagging
The very simplicity and open nature of the basic, standardized QR code—features that allowed for its massive global adoption—also create a specific security risk known as attagging. This vulnerability involves a malicious actor physically placing a sticker containing a fraudulent QR code directly over a legitimate one. Because the underlying ISO-standardized code is openly known and easily replicated, users scanning the surface may unknowingly interact with the malicious link or data embedded in the overlaid tag.
