This isn’t a specific artwork or project, but I know that “denial-of-service” attacks are sometimes used by hacktivism groups to make a certain website unavailable to users. I’m not sure about how a denial-of-service attack works specifically, but it basically leads to a server overload. It’s a crude example of hacktivism for sure, but I thought it would fit because the internet group “Anonymous” has used denial-of-service attacks in the past to bring down websites of organizations of which they find fault with. For example, recently on January 20, 2012, they used denial-of-service attacks on the Department of Justice and FBI websites to call attention to the website Megaupload being shut down.
