rising QR Code threats drive Innovation in Mobile Security

The increasing prevalence of QR codes in daily life – from marketing campaigns to digital payments – has unluckily been accompanied by a surge in malicious activity known as “QRishing” (QR code phishing). This emerging threat has spurred the progress of proactive security solutions, with a recent collegiate contest highlighting promising new approaches to safeguarding users.

A competitive Landscape for Security Solutions

The 5th Future and Software Contest, focused on “Information Security SW Web and App Development,” recently concluded with a highly competitive field of 204 teams, representing 609 students. Sponsored by Ciswon and Eduplus, the contest saw participants tackle critical issues like mobile information security, data privacy, artificial intelligence vulnerabilities, deepfakes, and industrial security. The event underscored a growing awareness of the need for robust security measures in an increasingly interconnected world.

The contest’s opening remarks were delivered by Lee Sang-hoon, Chairman of Future and Software, who emphasized the legacy of innovation established by the organization’s founder, Lee Joo-yong, a pioneer in bringing computer technology to Korea. Chairman Lee expressed optimism about the students’ potential to contribute significantly to the software industry.

“Mijung” Team Wins with Real-time QR Code Threat Detection

Taking the grand prize was the “Mijung” team from Daegu Catholic University, comprised of students Lee Ji-won, Ona-hee, and Lee Si-eon.Their winning project, “Trust QR,” addresses the escalating problem of QRishing by providing a real-time detection solution. Recent statistics indicate a 150% increase in reported QR code scams in the last year alone, demonstrating the urgency of this issue.The team’s solution focuses on three key areas: rigorous QR code safety testing, proactive detection and blocking of malicious codes, and the implementation of a machine learning model for accurate threat identification. Unlike simply relying on users to visually inspect a QR code, Trust QR operates in the background, analyzing the code’s destination before a user is redirected.This is akin to a spam filter for email, preventing users from accessing harmful content.

Automating Security with Machine Learning and AI

Mijung leveraged Auto ML to streamline the development process for their machine learning and deep learning models, automating tasks like data preprocessing, model training, evaluation, and deployment. The team utilized python and Android app development to create a user-amiable application.

Looking ahead, Mijung plans to refine their machine learning models, integrate advanced hooking techniques, and explore compatibility with existing security platforms to broaden the reach of their solution. They also envision a sustainable business model based on targeted advertising and partnerships with security-conscious businesses.

Beyond the Winner: Recognizing Innovation in Cybersecurity

While Mijung secured the grand prize (a 5 million won award and a high-end laptop), other teams were also recognized for their contributions. The Excellence Prize was awarded to the AEICE team (Go Eun
