Quishing

Quishing is phishing through a QR code, so the malicious link is hidden in an image that email filters and users cannot read at a glance.

How it works

QR codes appear in emails, PDF attachments, parking meters and posters. Scanning them opens the link on a phone, outside the protections of a work computer.

The destination is usually a credential or payment page; physical stickers over genuine codes are also common.

How to protect yourself

  • Check the URL a scanner shows before opening it; be wary of codes in emails and on stickers.
  • Decode suspicious codes with a tool that shows the link defanged.
