QR Code Security: Protecting Yourself from Quishing
You’ve likely scanned a QR code today—whether it was for a café menu in Melbourne, a parking meter in Sydney, or a discount offer in your inbox.
QR codes are everywhere, and while they make life easier, they’ve also opened the door to a rising cyber threat: quishing.
Quishing, short for QR code phishing, is one of the biggest challenges in QR code security today. Scammers hide malicious links inside fake QR codes, tricking people into giving away personal details or making fraudulent payments.
Let’s look at how this scam works, why it’s on the rise in Australia, and how you can protect yourself.
What is Quishing?
Quishing works much like traditional phishing—except instead of a suspicious email link, the bait is a QR code.
Criminals create a fake QR code that directs you to:
-
Fake login portals for services like MyGov or Australia Post
-
Dodgy payment sites that steal your credit card details
-
Malware-infected pages that compromise your device
Because all QR codes look alike, spotting a scam is harder—making QR code security even more important.
Real Australian Examples of Quishing
Unfortunately, this isn’t a distant threat—Australians are already being targeted.
-
Sydney parking scam – Fraudsters covered genuine pay-by-phone stickers with fake QR codes, tricking drivers into paying on fraudulent sites.
-
Brisbane café Wi-Fi trap – Customers scanning table QR codes were led to a bogus Wi-Fi login page that stole passwords.
-
Fake MyGov letters – Scammers mailed notices with QR codes that redirected to phishing sites imitating government portals.
Each case underlines why businesses and individuals must take QR code security seriously.
Why Quishing is Becoming Common
A few factors explain why scammers love QR codes:
Post-COVID habits
Australians embraced QR codes during the pandemic, and our trust in them is now being exploited.
Easy for criminals
Anyone can generate a QR code in seconds with free tools—no hacking skills required.
Harder to verify
A QR code hides its destination, making it harder to judge safety at a glance.
This combination makes QR code security more urgent than ever.
Many new phones show the url after scanning allowing you to see if it looks valid however older phones not so much.
Another handy trick is using Google Lens to check QR codes before opening them. Instead of scanning directly, open Google Lens on your phone, point it at the code, and it will show you the full link in plain text.
This gives you the chance to spot any dodgy URLs—like misspellings or strange domains—before you click through. It’s a simple extra step that adds an extra layer of QR code security.
How to Improve QR Code Security
You don’t need to stop using QR codes—just use them wisely.
For Everyday Users
-
Preview before opening – Most smartphones show a link preview; check the domain carefully.
-
Trust official sources – For payments or logins (e.g., MyGov, banking), go directly to the app or website.
-
Watch for tampering – Avoid codes that look like stickers slapped over existing signage.
For Businesses
Businesses play a key role in QR code security. To protect your customers:
-
Use branded QR codes with logos and colours
-
Print directly on menus, flyers, or invoices instead of stickers
-
Track and manage codes using secure platforms like QR Codes Australia
These steps make your codes harder to counterfeit while boosting customer trust.
