Anonymous

Anonymous (used as a mass noun) is a loosely associated international network of activist and hacktivist entities. A website nominally associated with the group describes it as "an internet gathering" with "a very loose and decentralized command structure that operates on ideas rather than directives". The group became known for a series of well-publicized publicity stunts and distributed denial-of-service (DDoS) attacks on government, religious, and corporate websites.

Operation Malaysia
On June 15, 2011, the group launched attacks on ninety-one websites of the Malaysian government in response to the blocking of websites like Wikileaks and The Pirate Bay within the country, which the group labels censorship of a basic human right to information.

Operation Facebook
In August 2011, someone created an account on Twitter with the name OP_Facebook and announced the "Operation Facebook". According to the links on the post, Anonymous was going to take down Facebook on November 5, 2011. The date "November 5" is believed to be attributed to the comics V for Vendetta, where the character "V" conducts his major plans every fifth of November in memory of Guy Fawkes. This operation isn't assuredly an Anonymous one. There was an earlier OpFacebook that was abandoned, and this current plan is a revival of the communication channels previously used. The plan is contentious and does not appear to be supported by the majority of those who say they are part of Anonymous. Operation Facebook, against popular belief, never showed any signs of itself. Facebook continued to run after the supposed Operation Facebook was to begin. On that day, Anonymous tweeted that they never announced Operation Facebook and that this was some guy's idea of a joke.

Operation Singapore
From August 20, 2013 to November 5, 2013, the group launched attacks on various websites -


 * Ang Mo Kio Town Council
 * PAP Community Foundation
 * The Straits Times (latest)
