Ransomware is malware that obstructs a user from accessing digital assets through various mechanisms. These assets are held hostage and inaccessible until the user pays a ransom. In most cases, this is accomplished using encryption where, once the malicious program executes, it will target and encrypt certain files and will release the decryption key at the time of payment. Some ransomware instances target only certain common user-generated files such as media and documents. In this case, system files and others required for the operating system to function correctly (user authentication, process execution, etc.) are unaffected. Others encrypt much more and seek to lock out entire systems.
