QR Code Scams (Quishing Attacks) – A Hidden Cyber Threat

QR codes are becoming part of our daily life – from scanning for restaurant menus 🍽️, online payments 💸, event tickets 🎟️, to login authentication.

But cybercriminals are now weaponizing QR codes to launch a new type of phishing called Quishing (QR Phishing).

⚠️ How Attackers Exploit QR Codes

1. Fake Payment QR Codes

Example: A scammer pastes a fake QR code on a shop counter.

You scan it and unknowingly transfer money directly to the hacker instead of the shop owner.

2. QR Codes in Emails / Messages

Example: You get an email saying “Scan this QR to verify your account”.

After scanning, it opens a fake login page that steals your username & password.

3. Malware via QR

Example: A QR code on a poster promises “Free Wi-Fi / Free Gift”.

Once scanned, it downloads malware or spyware into your phone.

🛡️ How to Defend Yourself (Defenses)

✅ Verify the Source – Only scan QR codes from trusted apps, shops, or official websites.

✅ Preview Links Before Opening – Use QR scanner apps that show you the URL before visiting it.

✅ Check for Tampering – Criminals often paste fake QR stickers on top of real ones (like at ATMs, shops, parking meters).

✅ Don’t Trust Random Codes – Avoid scanning QR codes from emails, flyers, posters, or social media posts unless 100% verified.

✅ Enable Multi-Factor Authentication (MFA) – Even if your password gets stolen, MFA adds an extra security layer.

🔐 Key Takeaway

Just because a QR code looks simple doesn’t mean it’s safe.

👉 One scan can expose your personal data, banking details, or even compromise your device.

Stay alert, stay secure! ⚡
