Did You Scan a QR Code to Get Here?
If so, you’re not alone. QR codes are everywhere these days—on flyers, menus, posters, receipts, and even street signs. They’re convenient, fast, and increasingly used in marketing, payments, and everyday transactions. But here’s the important question: Can you trust the QR code you scanned?
At Bison Security Co., we believe cybersecurity and digital privacy begin with awareness. In this post, we’ll break down the hidden risks of scanning them, real-world examples of scams, and practical steps you can take to protect yourself and your loved ones.

The Rise of QR Codes: From Convenience to Cyber Risk
QR (Quick Response) codes were originally developed in the 1990s for tracking car parts, but they exploded into mainstream use during the COVID-19 pandemic. Restaurants began using them to replace physical menus, businesses used them for touchless check-ins, and advertisers embedded them everywhere.
While they may seem harmless, these codes are simply visual links. And just like with email or websites, those links can be malicious.
The Problem: You Can’t See Where It Goes
Unlike clicking a link in your browser, where you can hover over it to preview the URL, QR codes are opaque. Scanning one might:
- Take you to a fake website that steals your login credentials.
- Launch a malicious app download.
- Redirect to a phishing form disguised as a trusted service.
- Trigger a payment request or crypto wallet drain.
- Embed malware or spyware onto your device.
Real-World Examples of QR Code Scams
1. Fake Parking Meters
Several U.S. cities reported QR code stickers being placed on parking meters, tricking drivers into paying a fake website. These codes looked official, but redirected users to fraudulent payment portals.
2. Restaurant Menu Hijacks
Attackers have been known to place their own codes over legitimate ones on restaurant tables. When diners scan them, they’re taken to spoofed pages that collect payment info, personal data, or try to install malware.
3. Crypto Wallet Scams
In the crypto world, QR codes are often used for sharing wallet addresses. Hackers generate fake QR codes with their own addresses, leading to irreversible transactions to the wrong destination.
Why This Matters for Families and Small Businesses
At Bison Security Co., we focus on helping families and small businesses stay digitally safe. QR code scams are particularly dangerous for our community because they target:
- Parents and kids who may scan codes for games, online classes, or product info.
- Seniors who trust printed materials more than digital ones.
- Small business owners who use QR codes for marketing, payments, or client sign-ups.
If you’re not verifying the source of every QR code, you’re exposing yourself to unnecessary risk.
7 Steps to Stay Safe Around QR Codes
1. Never scan a QR code from a random source.
If it’s stuck on a pole, flyer, or street sign, be skeptical. QR codes can easily be tampered with or replaced.
2. Use a secure QR scanning app.
Some apps and devices preview the URL before opening it. Avoid apps that automatically launch the link.
3. Look for signs of tampering.
Check if the QR code looks like a sticker over another one. This is a common red flag.
4. Don’t enter sensitive information.
If a QR code leads to a form asking for logins, payment details, or personal data, stop and verify the URL.
5. Avoid scanning QR codes in emails or text messages.
These are especially risky and often used in phishing campaigns.
6. Update your devices regularly.
Make sure your phone, browser, and antivirus software are up to date to protect against exploits.
7. Teach your family and staff.
Awareness is your first line of defense. Talk to your kids, parents, and employees about QR risks.
What to Do If You Think You Scanned a Malicious QR Code
- Immediately close the webpage or app it opened.
- Clear your browser history and cache.
- Run a malware/virus scan on your device.
- Change any passwords you may have entered after scanning.
- Contact your bank or credit card provider if payment info was involved.

Not all QR codes are dangerous. Many businesses use them securely every day. But just like email and websites, they can be abused by attackers.
