Denial of Service (DoS) is a common attack method used to flood network connections with the intention to render the network server unusable. DoS attacks are typically motivated by retaliation, perhaps from a fired employee or various other reasons, including social hacktivism or cyber terrorism. Most DoS attacks target web servers by overwhelming them with SYN requests faster than the server can respond to them. DoS attacks can barrage a server by depriving it of other critical resources such as CPU, memory, and bandwidth possibly leading to a system crash.
The name “anonymous” is a term widely used in online blogs and forums to hide the identity of an individual who post commentaries, images, or upload videos. The origins of the groups Anonymous can be traced back to the /b/ board of 4chan, a website that originally started out as an image board, where users can post almost anything anonymously and without fear from reprisal and criticism. The name Anonymous would soon be touted as the name of an activist group who use the Internet as their engine of protest. Anonymous isn’t centrally organized nor does it have any leadership structure, but rather, a system of self governing as interpreted by a group or individual at the time of action for which its purpose is determined to bring global attention to social events from around the world.
