To fight the increasing threat posed ransomware, security researchers practitioners have developed decryption tools. These aim help victims recovering data, generally decrypting compromised without paying ransom. Unfortunately, there has been minimal research on effectiveness recovery There scant understanding regarding extent which these tools can actually recover data. The presented this work aims cover gap providing an empirical study tools’ terms For doing so, we tested total 78 created 11 companies against 61 ransomware samples. That allows us present in-depth critical discussion real studied. We found nearly half fail satisfactorily conclude still lot be done before make positive impact victims. finish our offering some additional insights recommendations could improving
