This post is full of bad news like this:
Radware released its 2018 Executive Application and Network Security Report. For the first time in the survey’s five-year history, a majority of executives (53%) reported paying a hacker’s ransom following a cyber attack.
Ouch. Like most hacking/scam/spam tools, they are usually popular because they work. Ransomware has been working. It will continue to grow and evolve so long as that is true.
