The rise of digital payments and touchless transactions has fueled the widespread adoption of QR codes across industries. From retail stores to banking and government services, scanning a QR code has become second nature to many Filipinos. But with convenience comes risk—are QR codes a tool for seamless transactions, or do they expose users to cyber threats?
In a recent episode of KakaComputer, host Andresito de Guzman sat down with Onil Jaia Leyda, Technical Solutions Consultant at ManageEngine, to explore the hidden risks and security challenges associated with QR codes.
QR Codes: A Growing Trend in Digital Transactions
With the Bangko Sentral ng Pilipinas (BSP) pushing for cashless transactions, QR codes have become a standard for payments, e-commerce, and even public transport systems. Their ability to store and transmit data instantly has made them an essential tool for businesses looking to streamline operations and enhance customer experiences.
However, this rapid adoption has also attracted cybercriminals looking to exploit security gaps. Attackers use QR phishing (quishing), malware injection, and fake payment diversions to steal sensitive information from unsuspecting users.
Understanding QR Code Threats
- QR Phishing (Quishing)
Cybercriminals generate fraudulent QR codes that, when scanned, redirect users to fake websites that mimic legitimate platforms. These sites collect login credentials, personal information, and financial data without users realizing they are being scammed.
- Malware Injection
Some QR codes prompt users to download apps or files that contain malicious software. Once installed, these programs can track keystrokes, steal passwords, or even hijack a device for remote access.
- Fake Payment Redirection
QR codes are widely used for digital payments, but scammers create counterfeit codes that reroute funds to fraudulent accounts. Because these scams are difficult to trace, victims often realize the fraud too late.
How to Protect Yourself from QR Code Scams
Given these risks, both individuals and businesses must take precautions when using QR codes. Here are some key best practices:
Verify Before Scanning – Ensure that QR codes come from trusted sources, especially when making payments.
Use Secure QR Scanners – Some scanning apps have built-in security features that detect suspicious links.
Check the URL Carefully – When redirected to a website, look for misspellings or unusual domain names that indicate a fraudulent site.
Enable Two-Factor Authentication (2FA) – Protect financial accounts by enabling extra security layers to prevent unauthorized transactions.
Be Cautious with QR Code-Based Downloads – Avoid scanning QR codes that prompt file downloads unless they come from a verified source.
The Future of QR Codes: Innovation vs. Security
As QR code adoption continues to grow, businesses and regulators must find a balance between innovation and cybersecurity. Solutions such as encrypted QR codes, AI-powered fraud detection, and stricter regulations can help mitigate risks while maintaining the convenience that QR codes offer.
Onil Jaia Leyda emphasizes the need for cybersecurity awareness and proactive security measures to protect consumers and businesses from emerging threats. Organizations that implement secure QR code practices will be better equipped to maximize the benefits of digital transactions while minimizing risks.
QR codes have transformed the way businesses and consumers interact in the digital landscape. However, their convenience must be matched with security awareness. By staying vigilant and implementing best practices, individuals and organizations can protect themselves from the growing wave of cyber threats targeting QR code technology.
As the digital economy continues to expand, one thing remains clear—security and innovation must go hand in hand to ensure a safer, more efficient digital future.
