What is Ransomware?

Ransomware is a type of malware that infects your system, personal or business data. You will receive an onscreen message that your files are now encrypted, with a demand for payment to restore access.

How they contact you

Generally, via an email containing a link or attachment, such as a word document or pdf. However malicious advertisements or websites can lead to infection of Ransomware.

What they're after

Cybercriminals are usually after payment to decrypt your files. If you pay the ransom, there is no guarantee they will unlock your files.
