What qr code attacks is, who it affects, and what a child should learn — a free entry from the Digital Guardians Threat Dictionary.

Target age range: Suitable for upper elementary to high school ages (approximately 10–18). Even younger kids encounter QR codes (in school or public), so early education helps. This lesson is especially key for teens who have more independence with smartphones in public places or online.

Threat definition

QR Code Attacks (Quishing) – A QR code is that square barcode you scan with your phone to open a link or information. While QR codes themselves are just tools, attackers exploit them by creating malicious QR codes that lead to dangerous outcomes. In a QR code phishing attack (“quishing”), the scammer makes a QR code that, when scanned, directs the user to a fake website or prompts a harmful action. Because people can’t read a QR code’s content with their eyes, we tend to trust that scanning it will do what the nearby instructions say (e.g., “Scan here for a free prize” or “Menu”). Scammers abuse that trust: the code might instead take you to a spoofed site that steals your login/password, trigger a malware download, or hijack a device function. These bad QR codes can be printed on stickers and slyly placed over real QR codes (like on restaurant tables or parking meters) or sent digitally via email/text. The core danger: when you scan a malicious QR code, you could unknowingly hand over sensitive info or infect your device – all because the QR code lied about where it was taking you.
