Hacker
Is anybody else reminded of Steve Jackson Games' "Hacker"?
You could spend an action "cleaning" up a system, removing everybody else who had compromised it.
(now, if only SJG would do a Hacker: Designer's Edition Kickstarter, after the success of the Ogre: Designer's Edition Kickstarter).
There are days I wish somebody would write a Warhol Worm that would infect every already infected botnet zombie out there, then "kill" them by overwriting the hard disk: the old "Nuke the entire site from orbit" approach to cleansing the Internet.
