As the authors know that traditionally, "Cryptography" is used for information processing and communications, it helps people to store information securely and it is used very frequently for private communications. But Cryptovirology is the study of applications of cryptography to build the malicious software (malware). It is an investigation, how modern cryptographic tools and paradigms can be used to strengthen, develop and improve new malware attacks. This is a forward engineering discipline that can be used for attacking rather than defending. In this paper, they present the clear process of "How the crypto virus can damage the victim's system, based on Extortion mechanism" with showing the live scenario that causes the loss of access to information, loss of control and loss of money also.
