What is Ransomware?
What it is
Ransomware is a type of malware that infects computers and encrypts or locks files and systems until a ransom is paid.
Ransomware works by infecting a computer, locking users out of the system (usually by encrypting the data on the hard drive), and then holding the decryption or other release key ransom until the victim pays a fee, usually in bitcoin
As far as impact is concerned, look no further than the WannaCry and Petya outbreaks that affected thousands. Affected hospitals had to turn away patients or shutdown their emergency wards. Car manufacturing plants had to stop production, and power grids were disrupted.
