Ransomware is easy to deploy and very effective – cybercriminals can inflict maximum damage if they encrypt your file server or database and if you haven’t backed up your data they can take your business offline. Ransomware is the term for the many variations of malware that infects your computer systems, locks your files and demands payment to access them.
A cryptovirology attack encrypts critical files and systems and renders them inaccessible to the owner.
Ransomware sometimes marks the files for permanent deletion or publication on the internet. The perpetrators then demand a payment (usually in untraceable cryptocurrency like Bitcoin) for the private key required to decrypt and access the files.
