QR Code Phishing (Quishing)
A growing cyber threat in 2026

What is Quishing?
Quishing is a phishing attack that uses malicious QR codes to trick users into scanning and visiting fake websites.
Instead of sending a clickable link, attackers hide the link inside a QR code.


Attackers use QR codes to:

  • Steal Microsoft / Google login credentials
  • Capture banking or payment details
  • Deliver malware to mobile devices
  • Redirect to fake payment pages


Common places you may see malicious QR codes:

  • Invoice emails
  • Posters or public advertisements
  • Fake restaurant menus
  • HR or internal company documents
  • Parcel delivery notices


How to protect yourself:

  • Don’t scan QR codes from unknown sources
  • Always preview the URL before opening
  • Be cautious of urgent login requests
  • Use mobile security or endpoint protection


Remember:

QR codes are not always safe — they can hide malicious links.
