Ransomware is a type of malicious software created to block a user or organization’s access to their computer files. It achieves this by encrypting the files and then demanding a ransom in exchange for the decryption key. Cyberattackers use this tactic to force organizations into a situation where paying the ransom becomes the simplest and most cost-effective way to regain access to their data. Some versions of ransomware also have additional features, such as stealing data, to further compel victims to pay.
