“Ransomware is the most profitable type of malware in history. In the past, attackers primarily tried to steal information and maintain long-term access to their victims’ systems and resources. They typically did not deny access to systems or destroy data. Ransomware has changed the game from stealthy access to extortion.
In a ransomware attack, victims pay attackers directly to recover their files. The emergence of anonymous currencies such as Bitcoin and Ripple has meant that attackers can profit easily and with relatively low risk. This makes attacks highly lucrative and funds development of the next generation of ransomware. As a result, ransomware is evolving at an alarming rate”.
