What appeared to be genuine nude photos of more than 100 celebrities were published online over Labor Day weekend, 2014, in a mass attack dubbed Celebgate. The celebrities pictured included Hunger Games star Jennifer Lawrence, who confirmed the photos were real, and pop star Ariana Grande, who said they were fake, among dozens of other A-list actors and musicians. The photos were first posted on the forum 4chan and then circulated on the Reddit subsection r/TheFappening. Apple says the hack was caused by a very targeted attack on user names, passwords and security questions, and not a breach of its systems. Hundreds of nude, semi-nude, and revealing pictures of female celebrities were leaked overnight after being stolen from their private collections.
