What Does Ransomware Do to an Endpoint Device?

Ransomware takes over an endpoint device such as a computer, tablet, mobile phone or network server, and encrypts the data. This makes it impossible for the user to access any of the files, applications, photos or anything else on the device unless they pay a ransom to have it all unlocked.

Basically what ransomware does to an endpoint device is shut it down and make it inoperable for the user. It can then spread from the endpoint device to the network and other connected devices as well.
