GandCrab ransomware

This is a specific form of malware whose goal is to encrypt the data on an infected server. This makes the data inaccessible to users and can cripple an organization. The cybercriminals will decrypt the data if their financial demands are met. Paying the ransom may or may not get your data back. Remember, you are dealing with criminals and their word is not to be trusted.

    1. Always use strong passwords.
