Fraudes en línea MurallApp.

Abstract

This research addresses the phenomenon of online fraud in Colombia, which has experienced an exponential growth of 859% in recent years, positioning Bogotá as one of the primary epicenters of cybercrime with over 15,000 reported cases in 2025. The study identifies that the vulnerability of users, particularly the millennial generation, stems from a lack of digital education and the absence of proactive technological protection tools. The primary objective is to promote an information security culture through the development of MurallApp, a comprehensive strategy that combines a mobile application for real-time fraud detection with multimedia educational programs. Utilizing a mixed-methods research approach that integrates documentary inquiry, quantitative surveys, and qualitative interviews with key stakeholders—including financial institutions and victims—a prevention model based on the pillars of trust, reputation, and security is proposed. The expected results are directed toward the reduction of risks associated with phishing, sextortion, and data loss, establishing a security protocol that empowers citizens and strengthens confidence in the national e-commerce ecosystem with a regional expansion projection by the year 2030.
