Definition – A type of malicious software designed to block access to a computer system until a sum of money is paid.
Example – A ransomware attack can encrypt your files with a secret key that will only be provided by the attacker should you pay the ransom.
Ransomware can be hidden in files that seem safe or legitimate, such as PDF and Excel files. Even if you pay, it is not guaranteed that the attacker will release the key to your files. For this reason, you should have regular backups of your computer stored in a secure location. Greencrypted provides anti-virus software that can protect against ransomware attacks, and a backup solution to keep your files safe just in case.
