Hackers Leak Explicit Photos of More Than 100 Celebrities

Jennifer Lawrence and Kate Upton among the victims of hacking from a cloud-based data storage network

Jennifer Lawrence, Selena Gomez and Kirsten Dunst were among an estimated 100 celebrities alleged to have private and explicit photos leaked online Sunday, after hackers apparently accessed their cellphones through a cloud-based storage network.

The photographs originally turned up on the website 4chan, where hackers claimed to have infiltrated the phones of more than 100 celebrities and promised to leak more images in the future.

The pictures were reportedly stolen from a cloud-based data storage network. Some posters claimed it was Apple’s iCloud system that was hacked, Mashable reports, though the company has not confirmed those rumors.

A spokesperson for Lawrence acknowledged the authenticity of the images, calling it a “flagrant violation of privacy” and vowing to prosecute anyone who shared the images online. “The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence,” the spokesperson said in a statement, People Magazine reports.

Actress Mary Elizabeth Winstead lambasted both the people who posted and viewed the images, which she said were taken in the privacy of her home with her husband.

Nickelodeon star Victoria Justice denied the authenticity of the images, accusing hackers of doctoring images.

McKayla Maroney, the teenage gymnast who won Olympic gold medals in the team and vault competitions in 2012, also tweeted that images of her were faked. Like Winstead, she had a message for the hackers:
