What is a ransomware attack?

Ransom + Software = Ransomware

Ransomware will either:

  • lock the computer to prevent the user from normal usage or
  • encrypt the data that it stored on the victim’s hard disk to prevent access.

Ransomware is a type of malware that forces its victim to pay the ransom through certain online payment methods so as to grand access to their system or to decrypt their data.

Payment is often required in the form of cryptocurrency such as Bitcoin.

In order to minimize the impact of ransomware maintain an offline backup of end-user data.

Example of Ransomware: Locky, CryptoLocker, Cerber, Simplelocker.
