Hacktivism (a portmanteau of hack and activism) is "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." It is often understood as the writing of code to promote political ideology - promoting expressive politics, free speech, human rights, or information ethics. Acts of hacktivism are carried out in the belief that proper use of code will have leveraged effects similar to regular activism or civil disobedience. Fewer people can write code, but code affects more people.
Hacktivist activities span many political ideals and issues. Freenet is a prime example of translating political thought (anyone should be able to speak) into code. Hacktivismo is an offshoot of Cult of the Dead Cow; its beliefs include access to information as a basic human right. The loose network of programmers, artists and radical militants 1984 network liberty alliance is more concerned with issues of free speech, surveillance and privacy in an era of increased technological surveillance.
Hacktivism is a controversial term. Some argue it was coined to describe how electronic direct action might work toward social change by combining programming skills with critical thinking. Others use it as practically synonymous with malicious, destructive acts that undermine the security of the Internet as a technical, economic, and political platform.
Essentially, the controversy reflects two divergent philosophical strands within the hacktivist movement. One strand thinks that malicious cyber-attacks are an acceptable form of direct action. The other strand thinks that all protest should be peaceful, refraining from destruction.
