Ransomware is a form of malware, or malicious software, used to encrypt sensitive files held in business and personal devices, essentially locking users out of their own data or networks. Once deployed, the ransomware encryption restricts access to files and the victim receives a notice that a “ransom” must be paid to unlock the data or device. The ransom request often requires payment by Bitcoin or other types of anonymous cryptocurrency. Access to data is supposed to be restored once the ransom is paid and the attackers provide a decryption key.
