A hacker known as Martha Root broke in and deleted three white supremacist websites at the end of a talk during the annual hacker conference Chaos Communication Congress in Germany.
I agreed with another comment that this is probably not cyber terrorism, because definitions of cyber terrorism indicate a wide spread impact on people while this only impacts a relatively small group. Your definition isn’t quite right either as one potential goal for cyber terrorism is to cause disruption or fear. Terrorism as a general term may be politically motivated but it doesn’t have to have the goal of influencing policy directly. Technically revenge can be a goal of terrorism.
