Abstract

Malware, classified as ransomware, encrypts data on a computer, preventing individuals from accessing it. The intruder then demands a ransom from the user for the password that unlocks the files. Recent cyberattacks against prominent corporate targets have increased the extensive media attention on ransomware. The primary reason for computer intrusions is financial gain. Ransomware targets individual owners of information, keeping their file systems captive until a ransom is paid, compared to malware, which permits criminals to steal valuable data and then use it throughout the digital marketplace. Ransomware's terrifying complexity level heralds a paradigm shift in the cybercrime ecosystem. Ransomware has become more mysterious, with some latest forms working without ever connecting to the Internet. In this chapter, the authors will discuss the overview of ransomware, the history and development of ransomware, some of the famous cases, the anatomy of ransomware attacks, types of ransomware attack vectors, and the prevention of such kinds of attacks in cyberspace.
