It's an amorphous group of people that can include anyone who wants to use the brand to put forth their cause, according to Internet activist Gregg Housh, formerly with Anonymous.
There’s also the real-world manifestation of the Anonymous movement, which has been represented at rallies around the world by protesters wearing the now-iconic Guy Fawkes masks obscuring their identity.
While there are no specific goals, there is an overarching desire to combat censorship, promote freedom of speech, and counter government control that sparks people in the so-called collective into action, according to Housh.
Anonymous is known to vigorously go after its targets. It has been associated with crashing Web servers, website defacement and leaking hacked private information.
For example, the group allegedly targeted computer security firm HPGary and its CEO, claiming that the company was going to disclose details of Anonymous members to the FBI.
The group also uses it tech-savvy abilities to promote causes it supports.
