QR Code Phishing: What Is Quishing?

QR code phishing, or quishing, hides malicious links inside scannable codes. Because people cannot read the destination, the trick is effective.

How quishing works

Attackers place fake codes on emails, posters, parking meters, or packages that lead to credential-stealing sites. Email scanners often miss links hidden in images.

Common scenarios

Fake parking payments, package delivery notices, and urgent login prompts are frequent. Some messages impersonate IT asking staff to scan a code to verify an account.

Spot the signs

Be wary of unexpected codes, stickers placed over existing ones, and pages asking for credentials or payment. Check the full web address before entering details.

Stay safe

Use your phone camera preview to inspect the link, avoid scanning codes from unknown emails, and type official addresses manually when in doubt. Enable multi-factor authentication.

For organizations

Include QR scenarios in training, scan inbound images, and give staff an easy way to report suspicious codes.

Putting it into practice

To apply this in your own organization, begin with a short assessment of where you stand on QR code phishing today. Write down who owns it, which tools are involved, and the single biggest gap. Fix the highest-risk gap first, assign a clear date, and review progress after thirty days. Share what you learn with the team so improvements stick, and document the decisions you make so new staff can follow them. Revisit the topic every quarter, because threats, tools, and business needs change quickly, and small regular adjustments are far easier than large emergency fixes.

Common mistakes to avoid

Many teams struggle with QR code phishing because they try to do everything at once, skip documentation, or treat it as a one-time project. Others rely on a single person who holds all the knowledge, or buy tools before defining the problem they need to solve. Avoid these traps by starting small, writing down simple procedures, spreading responsibility across the team, and checking results on a regular schedule. If something is not working, adjust quickly instead of abandoning the effort, and keep a short log of what you changed and why. That record makes future decisions faster and helps new colleagues understand the reasoning behind your approach.
