Small businesses, large businesses, hospitals, police stations and entire cities are being brought to a halt by ransomware. Billions of dollars in productivity is being lost and billions in ransom are being paid. Ransomware is huge! After a slight decrease in activity in 2017, ransom-asking programs have come roaring back.

Swap a few bytes around, and a previously recognized malware program becomes unrecognizable. Malicious hackers and malware can change their tactics at will.
