Ransomware is a malicious piece of software that encrypts a user or company’s files. Once encrypted by an attacker it is almost impossible for the victim to regain access to the files without a “decryption” key that is held by the attacker or “file kidnapper”. The “kidnapper” of the file(s) then demands a fee from the company to regain access to its own files. Typically, the attacker, sets a short time span -- usually 72 hours or less -- for the infected user or entity to fork over a ransom. (Attackers do not like to leave digital trails and use temporary servers to accomplish their illicit activity). The ransom is usually payable in Bitcoin – an anonymous currency increasingly popular with criminals. The hackers will display some sort of screen or webpage explaining how to pay to unlock the files.
