Anonymous is a single person.
Anonymous (group) . 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 '' . Related groups LulzSec and Operation AntiSec carried out cyberattacks on U.S. government agencies , media , video game companies , military contractors , military personnel , and police officers , resulting in the attention of law enforcement to the groups ' activities . Supporters have called the group `` freedom fighters '' and digital Robin Hoods while critics have described them as `` a cyber lynch-mob '' or `` cyber terrorists '' .
