Web3 and Ransomware Attacks

This chapter explores the escalating threat of ransomware attacks and the potential of blockchain technology as a defense mechanism. Ransomware, known for encrypting victims’ files and demanding ransoms, presents a significant threat across various sectors. This chapter examines blockchain’s strengths and weaknesses in combating ransomware, focusing on its immutability, data protection, and decentralized storage capabilities. It discusses the technical architecture of blockchain in resisting ransomware, including data entry, chain linkage, distributed ledgers, and consensus mechanisms. The chapter also addresses implementation considerations like smart contract programming, data access control, and integration with external threat intelligence for automated incident response.
