QR codes are everywhere these days. You can find them on restaurant menus, flyers, and posters. They are used both offline and online. QR codes are convenient and easy to use. You scan them with your smartphone camera and then directed to a link, a coupon, a video, or some other online content.
With the rise in popularity of QR codes and convenience comes an unfortunate dark side. Cybercriminals are exploiting this technology for nefarious purposes. Scammers create fake QR codes, steal your personal information, infect your device with malware and often trick you into paying money.

The QR Code Resurgence
QR codes were originally designed for tracking parts in the automotive industry. They have experienced a renaissance in recent years. As a result, they’re used as a form of marketing today.
They offer the convenience of instant access to information. You 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
Scammers can print 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 is legitimate.
The fake code may direct you to a phishing website, which asks you to enter sensitive data such as your credit card details, login credentials, or other personal information. Alternatively, scanning the QR code may prompt you to download a malicious app that contains malware that can spy on your activity, access your copy/paste history, access your contacts or lock your device until you pay a ransom.
The code could also direct you to a payment page that charges you a fee for a supposedly free service or product.
Here are some tactics to watch out for.
Malicious Codes Concealed
Cybercriminals tamper with legitimate QR codes, embedding malicious content that redirects users to fraudulent websites.
Fake Promotions and Contests
Scammers use QR codes to lure users into fake promotions or contests. When users navigate to the counterfeit website, they are prompted to provide personal information, which can lead to potential identity theft or financial fraud.
Malware Distribution
Some malicious QR codes start downloads of malware onto the user's device. This can result 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 the code prompts you to enter personal information.
Use a QR Code Scanner App
Consider using a dedicated QR code scanner app. Use that rather than the default camera app on your device. Some third-party apps provide extra security features such as code analysis and website reputation checks.
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. Do not scan QR codes 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.
Be Wary of Websites Accessed via QR Code
Don't enter any personal information on a website that you accessed through a QR code. This includes things like your address, credit card details, login information, etc.
Don't pay any money or make any donations through a QR code. Only use trusted and secure payment methods.
