Cyber criminals seek to exploit human or organizational vulnerabilities, in order to steal, exploit – and even resell via illegal markets – confidential and personal information (e.g. passwords, user profiles, financial data, etc), that are so used to achieve economic profits. Additionally, more structured bodies (such as terrorist and other groups) carry out cyber-attacks against Corporates and Public Institutions, both to generate strategic disruptions and to make massive financial revenues, usually made through the ransom paid by the victim to recovery vital information, blocked by a malicious software (the ransomware).
