Cyber terrorism involves using computers and telecommunications to conduct terrorist activities such as violence, destruction, or disruption to create fear and influence governments. The FBI defines terrorism as unlawful violence against people or property to intimidate or coerce for political or social goals. The US National Infrastructure Protection Center also defines cyber terrorism as criminal acts using computers and telecommunications to cause confusion and uncertainty in a population to influence them politically, socially, or ideologically. Cyber terrorists prefer these methods as they are cheaper than traditional attacks, more difficult to track, allow anonymity, have no physical barriers, and enable remote and widespread attacks impacting many people.
