A list of the alleged victims has also appeared online, Buzzfeed noted. There are 101 names in total.

Some of those women include Aubrey Plaza, Candice Swanepoel, Cara Delevingne, Cat Deeley, Hillary Duff, Kaley Cuoco, Kate Upton, Kelly Brook, Kim Kardashian, Lea Michele, Michelle Keegan, Selena Gomez, Rihanna and Vanessa Hudgens.

To those of you looking at photos I took with my husband years ago in the privacy of our home, hope you feel great about yourselves.

Celebrities have often been targets of phone hackers, with Christina Hendricks, Olivia Munn and Blake Lively recent victims.

In 2012 a man was sentenced to 10 years in prison for releasing nude images of Scarlett Johansson on the internet.

Seth Rogen criticized the hacker on Twitter, writing:

Posting pics hacked from someone's cell phone is really no different than selling stolen merchandise.

SHARE THIS QUOTE:

I obviously am not comparing women to merchandise. Just legally speaking, it shouldn't be tolerated to repost stolen pics.
