Quishing is a type of QR code-based phishing attack that is becoming increasingly prevalent as QR codes gain more usage across various sectors.

This article explores quishing, the associated risks, examples, and strategies for protection.

QR Code Quishing what is it?

What is Quishing?

Quishing is the practice of using a QR code to trick individuals into visiting malicious websites or downloading malware. It is a form of phishing that relies on QR codes instead of traditional email or text-based links.

According to Cloudflare, "Quishing occurs when an attacker leverages QR codes to conduct phishing attacks, directing victims to fraudulent websites that request personal or financial information."

How Does Quishing Work?

Quishing operates by generating a QR code that, when scanned, directs users to malicious websites or prompts them to download harmful files. Here’s how attackers typically execute a quishing attack:

  1. Creating a fake QR code: Attackers generate a QR code that contains a phishing URL or malware.
  2. Replacing legitimate codes: They might replace real QR codes, such as those on restaurant menus, parking meters, or business advertisements, with fraudulent ones.
  3. Scanning and data theft: Once users scan the QR code, they’re unknowingly directed to a site designed to steal personal information, credentials, or install malware.

Real-World Example:

In a recent case, restaurant patrons were tricked by fake QR codes placed on menus, leading them to enter credit card details on a phishing site disguised as the restaurant's payment page.

What Happens If You Scan a Fraudulent QR Code?

When you scan a fraudulent QR code, a variety of harmful outcomes can occur:

  • Redirection to phishing sites: Users are sent to fake websites that look legitimate but are designed to steal credentials or personal information.

  • Credential theft: Directing users to login pages that appear legitimate but are designed to steal login details.

These attacks take advantage of the trust users place in QR codes, assuming them to be safe and secure.

How to Detect a Quishing Attack?

Detecting a quishing attack can be tricky, but there are signs to watch for:

  • Suspicious URLs: Always inspect the URL the QR code is directing you to before taking action. Use secure scanning apps that preview URLs.
