Payment system vulnerabilities in the Metaverse

Abstract

The Metaverse—which is a burgeoning virtual environment where users engage in social, educational, and commercial activities—has introduced new complexities in digital payment systems. This chapter examines the various vulnerabilities inherent in Metaverse payment systems, ranging from smart contract flaws to phishing and social engineering attacks. As these systems often involve real-world financial transactions or cryptocurrencies, they present attractive targets for exploitation. Through case studies and analysis, this chapter highlights common attack vectors, including quick response (QR) code manipulation, identity theft, and API vulnerabilities, while also providing mitigation strategies such as smart contract best practices, secure authentication mechanisms, and user education. This chapter also discusses future challenges, such as the evolving threat landscape posed by artificial intelligence (AI) and quantum computing, and the growing influence of decentralized finance (DeFi) within the Metaverse. The findings underscore the urgent need for robust security measures and collaborative efforts to protect users and ensure the integrity of payment systems in this rapidly evolving virtual world.
