Ransomware, like its name, is used to ask a ransom.

It could be related to email attachments and phishing, and then, there are other kinds of ransomware, such as NotPetya, which are designed to exploit existing vulnerabilities.

However, just because your company has decided to pay the hacker, it doesn’t always guarantee that the key will be granted. This is also one of the many reasons why ransomware is so dangerous. In most cases, unsuspecting employees are tricked to give admin or access details, which the hacker users to encrypt data or files.
