| Description | (Cornell University) The commoditization of Malware-as-a-Service (MaaS) allows criminals to obtain financial benefits at a low risk and with little technical background. One such popular product in the underground economy is ransomware. In ransomware attacks, data from infected systems is held hostage (encrypted) until a fee is paid to the criminals. This modus operandi disrupts legitimate businesses, which may become unavailable until the data is restored. A recent blackmailing strategy adopted by criminals is to leak data online from the infected systems if the ransom is not paid. Besides reputational damage, data leakage might produce further economical losses due to fines imposed by data protection laws. Thus, research on prevention and recovery measures to mitigate the impact of such attacks is needed to adapt existing countermeasures to new strains. | |
