Ransomware

Ransomware (also referred to in some cases as cryptoviruses, cryptotrojans or cryptoworms) comprises a class of malware which restricts access to the computer system that it infects, and demands a ransom paid to the creator of the malware in order for the restriction to be removed. Some forms of ransomware encrypt files on the system’s hard drive, while some may simply lock the system and display messages intended to coax the user into paying. Modern ransomware attacks were initially popular within Russia, but in recent years there have been an increasing number of ransomware attacks targeted towards other countries, such as Australia, Germany, and the United States among others.
