Cryptovirology: Virus Approach

  title={Cryptovirology: Virus Approach},
  author={Saurabh Anandrao Shivale},
Traditionally, "Cryptography" is a benediction to information processing and communications, it helps people to store information securely and the private communications over long distances. Cryptovirology is the study of applications of cryptography to build the malicious software. It is an investigation, how modern cryptographic tools and paradigms can be used to strengthen, develop and improve new malicious software attacks. Cryptovirology attacks have been categorized as : give malware… Expand

Better understanding is given of the concept of “Cryptovirology” which presents how cryptography can also be misused in the world of cyber crime. Expand
Overinfection in Ransomware
It is shown that the overinfection in ransomware can have four levels: Level 0 to ensure that the ransomware is not executed twice at the same time on the same machine, Level 1 to avoid re-encrypting its encrypted files, Level 2 to coordinate between its infections on thesame machine and Level 3 to manage the infection between many target machines in the same computer park.

Cryptovirology: extortion-based security threats and countermeasures
The idea of Cryptovirology is presented, which employs a twist on cryptography, showing that it can be used offensively to mount extortion based attacks that cause loss of access to information, loss of confidentiality, and information leakage, tasks which cryptography typically prevents. Expand
An Implementation of Cryptoviral Extortion Using Microsoft's Crypto API
This chapter presents an experimental implementation of cryptoviral extortion, an attack that we devised and presented at the 1996 IEEE Symposium on Security & Privacy [16] and that was recentlyExpand
