What are the types of ramsomware?

Before starting to create NAS (like Synology or NAS) ransomware protection, you need to know more about ransomware. In fact, it has two types in the following:

Locker ransomware: It directly lock users out of system or desktop while leaving only a window telling you that your files  have been encrypted and ask for ransom, WannaCry Ransomware Attacks 2017, for example. Thankfully, it doesn't result in a complete loss or access to important files. And you can choose to reinstall Windows to remedy your computer if you have a system backup before this happen. 

WannaCry Ramsome

Encrypting or Cryptographic ransomware: It blocks access to your files by encrypting files in place and your files are decrypted when you pay for the ransom. But there are many reports say only a percentage of files are recovered finaly. This type of ransomware is most likely to affect your NAS or shared storage.

It is essential to protect NAS from ransomware

Evidently, ransomware is a big threat to those who manage network-attached storage (NAS) or other network-based devices, even every computer user. So, it is necessary to protect NAS from ransomware protection. 

In 2017, there is a big ransomware named WannaCry, which spreads like a worm through NSA cyber weapon called Eternal Blue. It infected over 200.000 computers worldwide. Once a computer is infected, it can spread to all the devices on the same network in seconds.
