QR codes are everywhere these days. You can find them on restaurant menus, flyers, and posters. They’re used both offline and online, providing a convenient way to access information. Just scan them with your smartphone camera, and you’re directed to a link, a coupon, a video, or some other online content.
However, with the rise in popularity of QR codes comes a darker side. Cybercriminals are exploiting this technology for malicious purposes. Scammers create fake QR codes that can steal your personal information or infect your device with malware, all while tricking you into paying money. At TechNellogic, a managed IT service firm in Missoula, MT, we emphasize the importance of exercising caution when scanning QR codes. This emerging scam highlights the potential dangers lurking behind those seemingly innocent squares.
The QR Code Resurgence
Originally designed for tracking parts in the automotive industry, QR codes have experienced a renaissance in recent years. They’ve become integral to various industries, including retail and hospitality, thanks to the convenience they offer for instant access to information. Unfortunately, cybercriminals are quick to adapt, and a new phishing scam has emerged, exploiting the trust we place in QR codes.
How the Scam Works
Scammers print out fake QR codes and place them over legitimate ones. For example, they might stick a fake code on a poster advertising a product discount or a movie. When you scan the fake QR code, thinking it’s legitimate, it may direct you to a phishing website asking for sensitive data, such as credit card details or login credentials.
Additionally, scanning the QR code may prompt you to download a malicious app that can:
Spy on your activity
Access your copy/paste history
Access your contacts
Lock your device until you pay a ransom
The fake code could also direct you to a payment page that charges you for something supposedly free. Here are some tactics to watch out for:
Malicious Codes Concealed
Cybercriminals often tamper with legitimate QR codes by adding a fake QR code sticker over a real one, embedding malicious content or redirecting users to fraudulent websites.
Fake Promotions and Contests
Scammers use QR codes to lure users into fake promotions or contests. When users scan the code, it may direct them to a counterfeit website that prompts them for personal information, leading to identity theft or financial fraud.
Malware Distribution
Some malicious QR codes can initiate downloads of malware onto the user's device, compromising security and potentially damaging device 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.
Use a QR Code Scanner App: Consider using a dedicated QR code scanner app instead of the default camera app on your device. Some third-party apps offer 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 to 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. Be careful when scanning codes in public places—don’t scan if they appear damaged or tampered with.
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 personal information on websites accessed through QR codes, including your address or credit card details. Only use trusted and secure payment methods.
