Ransomware

Ransomware (also known as rogueware) is malicious software, kind of computer virus that locks an access to a computer or to the data. The author then demands ransom for providing access key (to your own data).

How does ransomware work?

Ransomware is a kind of computer virus that is activated after uploading to your computer and encrypts your data or an entire access to the computer. The author then demands ransom through an anonymous payment channel, often through Bitcoin. After the payment he send you an access key by which you are able to open data (or computer, phone) again. If you do not pay, your data stay locked forever.
