You’ve probably scanned a QR code this week without even thinking twice about it. Maybe it was at a restaurant to view the menu, at church to register as a first-time visitor, or to sign up for a community program or conference. QR codes have become part of our daily rhythm: quick, contactless, and convenient.
We’ve learned to trust them. But that’s exactly what cybercriminals are counting on.
In recent years, attackers have discovered a new way to exploit this everyday habit through a technique known as Quishing, short for QR code phishing. Instead of sending suspicious-looking links that people might hesitate to click, they hide those links inside QR codes. The moment you scan one, you could be redirected to a fake website designed to steal your login details, payment information, or other sensitive data.
What Is Quishing and How Does It Work?
At its core, Quishing works by taking advantage of trust and convenience. A QR code doesn’t show you what’s behind it. You only find out after scanning.
Here’s how attackers typically pull it off:
They create a malicious QR code and place it where you’d least expect trouble: an email from your “bank,” a printed flier, a event ticket machine, or even a church bulletin. The message around it usually sounds urgent or familiar, such as “Confirm your registration,” “Update your details,” or “Verify your account.”
Once scanned, the QR code takes you to a fake website that looks convincing enough to make you drop your guard. You enter your credentials, maybe even payment details, and your information ends up in the wrong hands.
Some advanced campaigns go even further, installing malware that silently monitors your device. What makes Quishing especially tricky is that traditional email filters or antivirus tools often fail to detect the threat since the malicious link is hidden inside the QR code image.
Why Quishing Is Becoming So Common
QR codes exploded in popularity during the pandemic, replacing menus, registration forms, tickets, and even offering touchless payments. People now scan them everywhere: in schools, offices, churches, and at community events.
That mass adoption, combined with habit, has made them a prime target. Attackers know most people don’t stop to check where a QR code leads before scanning, and that’s where the danger lies.
In a world where phishing emails are becoming easier to spot, Quishing feels fresh, familiar, and harmless. That makes it effective.
Recently the government agency NITDA (National Information Technology Development Agency) issued a public warning that scammers are increasingly using QR codes for phishing scams, payment fraud, data theft, and identity theft.
How to Stay Safe from Quishing
You don’t need to stop scanning QR codes; you just need to scan smarter. A few simple habits can make all the difference:
- Pause before scanning: If the QR code looks out of place or unfamiliar, don’t rush to scan it.
- Preview the link: Most smartphone cameras let you see the URL before opening it. Take a second to verify it looks legitimate and uses https://.
- Watch for tampering: Be cautious if you notice QR code stickers placed over printed originals on posters, menus, or notices.
- Avoid sharing sensitive data: Never enter your login credentials or payment info on a site you reached through a QR code, especially if it’s from an unsolicited message.
- Educate your team: Employees should understand that QR code phishing is real. Regular awareness training helps spot and stop these attempts early.
- Verify before acting: If a QR code claims to be from your bank, company, or a familiar organization, double-check through another official channel before scanning.
Next time you’re handed a QR code, whether it’s at a café, a church service, or a community event, take a moment to think before you scan. That small pause might just protect you from a very modern cyber trap.
