All Photo List Hollywood Celebrity hacked

Some of Hollywood's most famous ladies — Jennifer Lawrence, Kate Upton, and Kirsten Dunst among them — were the victims of an online hacker who lifted personal photos from their computers, phones, or other digital devices and posted them on the Internet over the weekend. The photos were all private, and some of them featured the women in various states of undress.

Who were the victims? How did it happen? Who did it? What's being done about it? What are these celebrities saying about this breach of privacy? We break it down…

What happened: A hacker or group of hackers accessed the personal photos of these women and posted them on the site 4chan. A source told the U.K.'s Guardian that the oldest photos date back to December 2011 and the newest are from Aug. 14. While it was initially thought that the photos were accessed through Apple's iCloud service, a rep for the company said that there was no breach in their systems themselves. Rather, a select group of celebrity accounts were compromised by hackers using standard phishing techniques to guess user names, passwords, and the answers to security questions.

The victims: Academy Award winner Lawrence seemed to have been the biggest target in what is being described as one of the biggest mass breaches of celebrity privacy in history. There are photos of her in swimsuits and there are photos of her in, well, nothing. Others who were reportedly victimized in this crude crime include model Upton; actresses Dunst, Lea Michele, Aubrey Plaza, Winona Ryder, Becca Tobin, Victoria Justice, Brie Larson, Jessica Brown Findlay, Teresa Palmer, Krysten Ritter, Mary Elizabeth Winstead, Yvonne Strahovski; singers Rihanna, Ariana Grande, and Avril Lavigne; TV host Cat Deeley; and Olympic gymnast McKayla Maroney.

What the victims are saying: So far, Lawrence, Upton, Dunst, and Winstead have all confirmed the legitimacy of the photos.

A spokesperson for Lawrence told The Insider With Yahoo, "This is a flagrant violation of privacy. The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence."

Upton's lawyer issued a statement to The Insider With Yahoo, saying, "This is obviously an outrageous violation of our client Kate Upton's privacy. We intend to pursue anyone disseminating or duplicating these illegally obtained images to the fullest extent possible."
