Furthermore, ransomware is a type of malicious software designed to extort money by blocking access to files or computer system until the ransom is paid. Paying the ransom does not guarantee that the files will be recovered, or the system restored. Lastly, social engineering is a tactic used to trick people to revealed sensitive information. It can be combined any of the cyber-threats to encourage people to click on links, download malware, or trust a malicious source.
