Hacking, the apolitical counterpart of hacktivism, is also not necessarily a form of terrorism. However, cyberterrorists often use hacking as a tool of terrorism. Terrorists may be tempted to use computer attacks for several reasons including the following. First, cyberterrorism can be relatively inexpensive. Second, terrorists can easily remain anonymous when they use computer terrorism. Third, the scope of the attack can potentially be larger than physically combative ones. Fourth, cyberterror can be launched and managed remotely and fifth, computer terrorism can garner instant and widespread media attention. Cyberterrorism is not only in the province of international terrorist organizations but may also be used by fanatical religious groups or even by disgruntled employess. Using computer terrorism can also become an adjunct to traditional forms of terror like bombs.

Weimann's report puts computer terrorism into perspective, dispelling myths and exposing realities.
