Canon-novellen Tarkin nämner en cyberattack som utförs av separatisterna under Klonkrigen:
It had been just nine months after the Battle of Geonosis that Count Dooku’s scientists had succeeded in slicing into the Republic HoloNet by seeding the spaceways with hyperwave transceiver nodes of a novel design. The Separatists could have kept quiet about the infiltration and tasked the nodes to gather intelligence about Republic military operations. Instead, Dooku—as if suddenly intent on winning hearts and minds rather than defeating the Republic with his droid armies—began using the HoloNet to broadcast propaganda Shadowfeeds, providing Separatist accounts of battle wins and disinformation about Republic war crimes, and in the end spreading apprehension among the populations of the Core Worlds that a Separatist victory was imminent.
A base under my command was recently attacked by unknown parties. The attack followed the successful sabotaging of a HoloNet relay station and the insertion of both prerecorded and real-time holovids, in an attempt to mislead us into dispatching reinforcements to a secondary base.
Det är inte klart hur HoloNet-relästationen saboterades, men igen är detta ett exempel på cyberwarfare.
