QR codes have become ubiquitous in various settings, from restaurant menus to flyers and posters. They offer a convenient way to access online content by scanning it with your smartphone camera. However, the surge in the popularity of QR codes has brought about a dark side, with cybercriminals exploiting this technology for malicious purposes. Scammers generate fraudulent QR codes, putting individuals at risk of personal information theft, malware infections, or financial deception. Caution is paramount when scanning QR codes, underscoring the hidden dangers behind these seemingly innocuous squares.

Once relegated to tracking automotive parts, QR codes have undergone a modern resurgence, finding new life as a marketing tool. Their popularity stems from the seamless access they provide to instant information, making them an indispensable asset in sectors like retail and hospitality.

However, with this renewed ubiquity comes a concerning twist. Cybercriminals, ever adaptable, have devised a phishing scam capitalising on the trust in QR codes. This underscores the need for heightened vigilance when engaging with these once-ingenious squares.

How the scam works

The scam operates by the scammer creating a counterfeit QR code, strategically placing it over a legitimate one—perhaps on a poster advertising a product discount or a movie. Unsuspecting individuals scanning the fake QR code believe it to be genuine. However, the consequences of this simple action can be severe, potentially leading to significant financial loss or identity theft.

The fraudulent code may redirect users to a phishing website, prompting the input of sensitive information such as credit card details or login credentials. Alternatively, scanning the QR code might initiate the download of a malicious app containing malware capable of activities like spying on user behaviour, accessing clipboard history, retrieving contacts, or even holding the device hostage until a ransom is paid.

Sometimes, the fake QR code leads to a payment page, deceiving users into paying a fee for something purportedly free.

Watch out for these tactics

Malicious Codes Concealed

Cybercriminals employ cunning tactics, overlaying legitimate QR codes with fake stickers, embedding malicious content or redirecting users to fraudulent websites. Their methods are sophisticated and often complex to detect, requiring users always to be vigilant.

Fake Promotions and Contests

QR codes entice users into counterfeit promotions or contests, redirecting them to bogus websites that solicit personal information, risking identity theft or financial fraud.

Malware Distribution

Some malicious QR codes trigger malware download onto users’ devices, compromising security and potentially causing damage or unauthorised access to personal data.

Stay Vigilant: Tips for Safe QR Code Scanning

Verify the Source

Exercise caution when scanning QR codes from unknown or untrusted sources. Confirm the legitimacy of the code and its source, especially if it requests personal information.

Use a QR Code Scanner App

Opt for a dedicated QR code scanner app instead of your device’s default camera app. Some third-party apps offer additional security features like code analysis and website reputation checks.

Inspect the URL Before Clicking

Before visiting a website prompted by a QR code, scrutinize the URL. Ensure it matches the legitimate website of the claimed organization.

Avoid Scanning Suspicious Codes

Trust your instincts. Refrain from scanning QR codes that appear suspicious, damaged, or tampered with, especially in public places. Scammers often exploit curiosity, so exercise caution.

Update Your Device and Apps

Regularly update your device’s operating system and QR code scanning apps to benefit from security patches that address known vulnerabilities.

Be Wary of Websites Accessed via QR Code

Avoid entering personal information on websites accessed through QR codes, such as addresses, credit card details, or login information. Exercise caution and refrain from making payments or donations through QR codes. Stick to trusted and secure payment methods.
