Why QR codes are risky
A QR code is just a machine-readable way to encode a link or other data, and its visual pattern gives no hint of where it leads. This concealment is exactly what scammers exploit: a QR code on a poster, email, or sticker could point anywhere, including a malicious site, and you cannot tell by looking. QR-code phishing, sometimes called quishing, uses this to trick people into visiting fake sites or making payments.
Preview before you open
The key defense is to preview the destination before actually opening it. Most modern phone cameras and QR scanners show the link they have read before you tap to visit it. Pause and read that address: does it go where you expect? If the preview shows an unexpected or suspicious site, do not proceed. This simple habit of reading the link first defeats most QR-code phishing, which relies on you scanning and tapping without looking.
Check the address bar after opening
If you do open a QR code's link, check the browser's address bar to confirm you are on the real site before entering anything. Phishing sites imitate real ones, but the address will differ. Be especially careful before typing passwords, payment details, or personal information, verify the address is genuinely the organization's official site. Treating a QR code's link with the same scrutiny as any suspicious link is the right mindset.
Be wary of physical and unexpected codes
Physical QR codes are easy to tamper with: scammers place stickers over legitimate codes on parking meters, menus, or payment terminals. Be cautious with codes in public places, especially for payments, and look for signs of tampering. Equally, treat unexpected QR codes in emails or messages with suspicion, just as you would an unexpected link, since they may lead to phishing sites or malware.
Guidance for payments and logins
For workplaces and individuals, apply extra caution to QR codes requesting payment or login. An unexpected QR code asking you to pay or sign in is a classic attack. Verify through a trusted channel, use the organization's official app or website directly rather than the code, and in a workplace, report suspicious codes. Never enter credentials or payment details via an unverified QR code, however official it looks.
The bottom line
QR-code phishing exploits the fact that a QR code hides its destination. Defend yourself by previewing the link before opening it, checking the browser address bar before entering anything, being wary of tampered physical codes and unexpected codes, and treating payment or login requests with extra caution. Understanding this lets you use QR codes safely without being tricked into fake sites or payments.
