QR codes have become a fixture of modern life, appearing on restaurant tables, product packaging, event posters, and payment terminals. Their convenience has made them nearly universal, but that ubiquity has also attracted the attention of cybercriminals. A new form of phishing attack called “quishing” exploits QR codes to steal personal information, and security experts warn that these scams are on the rise.
A Virginia Beach-based technology company has developed a mobile application designed to address this growing threat. Qrblox, launched by Terahertz Inc., combines scanning technology with security features aimed at protecting users from malicious QR codes before they can cause harm.
The app distinguishes itself through its ability to scan QR codes from multiple sources. While most smartphone cameras can scan codes directly, Qrblox allows users to scan codes from photos, screenshots, or images already saved in their device’s gallery. This functionality addresses situations where users encounter QR codes in digital formats or photographs that cannot be scanned in real-time, such as images of restaurant menus, promotional materials, or social media posts.
At the core of the app’s security approach is its URL inspection feature. Rather than immediately redirecting users to a website after scanning a code, Qrblox displays the embedded URL and provides an AI-generated summary of what the destination website contains. This preview system gives users an opportunity to evaluate whether a link appears legitimate before visiting it, potentially stopping phishing attempts that rely on users clicking through without hesitation.
“In today’s world, people need to be more aware of the threats that come with scanning QR codes, especially with the rise of quishing scams,” says Sarah Oh, CEO of Qrblox. “Qrblox was built to give consumers peace of mind by ensuring they’re scanning QR codes safely. Our app offers both convenience and security, empowering users to engage with QR codes confidently.”
Quishing attacks typically work by embedding malicious URLs within legitimate-looking QR codes. These codes might be placed over authentic codes on parking meters, restaurant tables, or promotional materials, or they might appear in digital communications designed to look like official correspondence from banks, delivery services, or government agencies. Once scanned, they can direct users to fake websites that harvest login credentials, payment information, or other sensitive data.
The problem has grown alongside the increased adoption of QR codes during recent years. What was once a niche technology became mainstream as businesses sought contactless solutions for menus, payments, and customer engagement. That rapid expansion created opportunities for bad actors to exploit users who had become accustomed to scanning codes without scrutiny.
Beyond its security features, the app includes several tools designed to enhance user engagement. An AI-powered chat feature allows users to interact directly with websites or their chatbots to gather additional information before visiting, providing another verification layer. The app also maintains a detailed scan history with calendar views and statistics, enabling users to track their scanning activity over time.
In a gamification element, Qrblox offers daily prizes to users who scan at least one QR code each day, encouraging regular use of the app’s security features. A daily leaderboard tracks the most active users, adding a social component to what is primarily a security tool.
The application is currently available for free download on iOS devices. By making the security app available at no cost, Terahertz Inc. aims to make QR code safety accessible to a broad audience of mobile users who regularly encounter these codes in their daily lives.
The development of specialized security applications like Qrblox reflects a broader trend in cybersecurity, where threats evolve alongside the technologies they exploit. As QR codes became more common, they naturally attracted the attention of scammers looking for new vectors to reach potential victims. The response from security-focused developers has been to create tools that maintain the convenience of QR codes while adding protective layers that were not originally part of the technology.
For users concerned about QR code safety, security experts generally recommend several practices: verify the source of a QR code before scanning, be wary of codes that appear to have been placed over existing codes, avoid scanning codes from unsolicited emails or text messages, and check URLs carefully before providing any personal information. Applications like Qrblox automate some of these verification steps, making secure scanning more accessible to users who may not have technical expertise.
As digital threats continue to evolve, the arms race between security developers and cybercriminals shows no signs of slowing. Tools that add protective layers to everyday technologies like QR codes represent one approach to keeping users safe while preserving the convenience that made those technologies popular in the first place.
