Generally spoken, Cyberwarfare describes a wide range of aggressive actions using and simultaneously targeting new media. Possible targets can be mere websites as well as computers managing sensitive data, stock exchange, controlling traffic or the like. Furthermore, it can occur on different “levels”, i.e. there seems to be a distinction between attacks on personal websites (personal context), the sabotage of governmental computers (political context) and the deprivation / destruction of information on corporation data bases (economical context).
