Cyberterrorism

Government officials and Information Technology security specialists have documented a significant increase in Internet problems and server scans since early 2001.

But there is a growing concern among federal officials that such intrusions are part of an organized effort by cyberterrorists, foreign intelligence services, or other groups to map potential security holes in critical systems.
A cyberterrorist is someone who intimidates or coerces a government or organization to advance his or her political or social objectives by launching computer-based attack against computers, network, and the information stored on them.

Cyberterrorism in general, can be defined as an act of terrorism committed through the use of cyberspace or computer resources (Parker 1983). As such, a simple propaganda in the Internet, that there will be bomb attacks during the holidays can be considered cyberterrorism. At worst, cyberterrorists may use the Internet or computer resources to carry out an actual attack. As well there are also hacking activities directed towards individuals, families, organised by groups within networks, tending to cause fear among people, demonstrate power, collecting information relevant for ruining peoples' lives, robberies, blackmailing etc.
