QR code security covers the risks and best practices around using QR codes safely. Since QR codes can encode any URL, they can potentially direct users to malicious websites.
The main risk is 'QR phishing' (quishing): attackers place malicious QR codes over legitimate ones, redirecting users to phishing sites. Best practices include: using a trusted generator, previewing URLs before visiting, using dynamic codes (the provider validates the destination), and placing QR codes in tamper-evident locations.
Use tamper-evident stickers for payment QR codes in stores.
Educate employees to preview QR code URLs before clicking.
Use branded, recognizable QR codes that attendees can trust.
QR codes themselves are just data. The risk is in what they link to. Always preview the URL before visiting.
Use tamper-evident materials, place codes in monitored areas, and use dynamic codes so you can verify the destination.
Be cautious. Preview the URL, check for stickers placed over original codes, and avoid codes from unknown sources.
