QR codes are everywhere these days; on restaurant menus, flyers, utility bills, commercials on your TV, posters and more. They’re used both offline and online and are convenient and easy to use. Just scan them with your smartphone camera and you’re directed to a link, a coupon, a video, or some other online content.
With the rise in popularity of QR codes comes an unfortunate dark side. Cybercriminals are exploiting this technology for nefarious purposes by creating fake QR codes. They can steal your personal information, infect your device with malware or trick you into paying money.
It’s crucial to exercise caution when scanning QR codes. This emerging scam highlights the potential dangers lurking behind those seemingly innocent squares.
The QR Code Resurgence
QR codes were originally designed for tracking parts in the automotive industry. They have experienced a renaissance in recent years, and are widely used as a form of marketing today.
They offer the convenience of instant access to information; simply scan a code. They’ve become an integral part of various industries, including retail and hospitality.
Unfortunately, cybercriminals are quick to adapt. A new phishing scam has emerged, exploiting the trust we place in QR codes.
How the Scam Works
The scammer prints out a fake QR code and place it over a legitimate one. For example, they might stick it on a poster that advertises a product discount or a movie.
You come along and scan the fake QR code, thinking it’s legitimate. The fake code may direct you to a phishing website, which may ask you to enter sensitive data such as your credit card details, login credentials, or other personal information.
Scanning the QR code could also prompt you to download a malicious app containing malware that can do one or more of the following:
- Spy on your activity
- Access your copy/paste history
- Access your contacts
- Lock your device until you pay a ransom
The code could also direct you to a payment page that charges you a fee for something supposedly free.
Here are some tactics to watch out for:
Malicious Codes Concealed
Cybercriminals tamper with legitimate QR codes. They often add a fake QR code sticker over a real one. They embed malicious content or redirect users to fraudulent websites.
Fake Promotions and Contests
Scammers often use QR codes to lure users into fake promotions or contests. When users scan the code, it may direct them to a counterfeit website. The website may prompt them to provide personal information leading to potential identity theft or financial fraud.
Malware Distribution
Some malicious QR codes start downloads of malware onto the user’s device resulting in compromised security, including unauthorized access to personal data and potential damage to the device’s functionality.
Stay Vigilant: Tips for Safe QR Code Scanning
Verify the Source
Be cautious when scanning QR codes from unknown or untrusted sources. Verify the legitimacy of the code and its source, especially if it prompts you to enter personal information.
Inspect the URL Before Clicking
Before visiting a website prompted by a QR code, review the URL. Ensure it matches the legitimate website of the organization it claims to represent.
Avoid Scanning Suspicious Codes
Trust your instincts. If a QR code looks suspicious, refrain from scanning it. Scammers often rely on users’ curiosity. Be careful when scanning QR codes that you see in public places. Don’t scan them if they look suspicious, damaged, or tampered with. Exercising caution is paramount.
Update Your Device and Apps
Keep your device’s operating system and QR code scanning apps up to date. Regular updates often include security patches that protect against known vulnerabilities.

Don’t pay any money or make any donations through an unknown QR code. Only use trusted and secure payment methods.
