In this chapter, you will examine how blockchain technologies, while enabling innovative financial systems, have also created new opportunities for fraud and criminal exploitation. You will learn how vulnerabilities in blockchain infrastructure, smart contracts, and centralized platforms have led to high-profile hacks, Ponzi schemes, and market manipulation. Through detailed case studies, you will explore the mechanics of major exploits, including cross-chain bridge attacks, ransomware operations, and transactions on darknet markets. You will understand how fraudsters use laundering techniques such as coin mixing, peeling chains, and shapeshifting to obscure transaction trails. By the end of this chapter, you will be familiar with the evolving landscape of blockchain-based e-crime and the analytical tools used to study and mitigate it.
