Ransomware is malicious code that renders the files and/or operating environment of an endpoint unavailable—be it an end user device or a server—until a payment is made to the cybercriminal.
Cybercriminals use ransomware to take over devices or systems to extort money. Once the malware has been installed, the hacker controls and freezes you out of it until you pay a ransom. In the earliest versions of ransomware, the attackers claimed that after you paid the ransom, you would get a decryption key to regain control of your computer.
