According to ESET, ransomware has grown by over 50% over the past year and 250% in the first quarter of 2017. Most attacks target the USA, which correlates with the general trend of ransomware in PCs. Ransomware is expected to continue to rise in its extent, and develop new and more powerful capabilities aimed at gaining the largest possible profits.
