"The term 'Anonymous' simply means without a name or anonymous identity, and the organization is a faction of anonymous hackers or hacktivists.
They have their own websites and IRC channels, regularly hold gatherings, and focus on online brainstorming rather than engaging in illegal underground activities. The group uses a voting system to decide on the best course of action for any given situation. This renowned hacker group is skilled in using Distributed Denial of Service (DDoS) attacks against government websites, well-reputed corporate networks, and religious sites.
Anonymous' most famous slogan is:
We are Anonymous
We are Legion
We do not forgive
We do not forget
Expect us."
