Ransomware: A Threat to Cyber Security

Abstract

All computer system using anti-virus that is because of threat against virus or malwares. Cybersecurity normally protect systems against all these viruses but as technology increasing the threat against technology also increasing. One of the new threat is Ransomware. It is a kind of virus which directly steal user’s money or it forces victim to pay some Ransom in order to get the access of victim’s original files. These all can be done through Cryptography. Fact is that cryptography is used to secure information but here Ransomware uses cryptography against it. Ransomware extort money from the victim by encrypting their valuable information. And to get back access of important files victim needs to pay some ransom. This paper tries to investigate the working of a Crypto Locker (Ransomware) and formal analysis of malware. This analysis leads to some conclusion concerning this phenomenon also few strength and weaknesses of money extort malware. This paper presents novel Ransomware, its encryption schema and some prevention, detection approaches.
