The prevalence of ransomware programs, both those that encrypt data and those that don't, has exploded over the past two years, with companies being increasingly targeted.

This includes programs that only lock the computer's screen to prevent its use as well as those that hold the data itself hostage by encrypting it -- the so-called cryptors. The rise of cryptors in particular has been significant, accounting for 32 percent of all ransomware attacks last year compared to only 7 percent the year before, according to Kaspersky Lab.
The number of users hit by crypto ransomware during the period studied grew 5.5 times to reach more than 700,000, while the number of corporate users in particular who encountered such threats rose from 27,000 to 159,000 -- an almost six-fold increase.
