The FBI is looking into the iCloud celebrity photos hack, though it did not say whether it has opened an investigation. An anonymous user began posting nude photos of actors and celebrities including Jennifer Lawrence, Kate Upton and Mary E. Winstead on the website 4Chan on Sunday afternoon after allegedly stealing the photos from the stars’ iCloud accounts. As the images began to spread, the user posted a list of dozens of other celebrities that he or she claims to have photos and videos of. Some photos have been verified by the subjects, while the authenticity of others has been contested.
