Anonymous is an amorphous collection of self-proclaimed “political hackers” who have taken credit for cyber-attacks in numerous countries in response to a wide variety of issues; groups claiming to be associated with Anonymous have attacked sites and businesses in the U.S., China, Iran, Syria and many other places.
