The dissertation looks at the phenomenon of hacktivism: the marriage of political activism and computer hacking. It defines hacktivism as the nonviolent use of illegal or legally ambiguous digital tools in pursuit of political ends. These tools include web site defacements, redirects, denial-of-service attacks, information theft, web site parodies, virtual sit-ins, virtual sabotage, and software development.
