After another batch of celebrity nude photo leaks went viral early this week, another female celebrity has been subject to online threats. UN Women Goodwill Ambassador Emma Watson is now targeted and threatened by online hackers. The actress alleged nudes will reportedly be released in less than four days.

An ominous message on the website, 4chan, has claimed Emma Watson best beware. Online hackers are reportedly planning something vile for the "Harry Potter" actress in four days with the website name: Emma You Are Next. The website includes a timer counting down to less than four days.

4Chan was the site responsible for the photo hack on iCloud's photo service and nude photo leak. Celebrities who have been victimized by nude photo hack and leak include "Hunger Games" star Jennifer Lawrence, former Nickelodeon stars Ariana Grande and Victoria Justice, Mary Elizabeth Winstead and Kate Upton.

A new batch of celebrity nudes have been released early this week of which include Rihanna, Kim Kardashian, Gabrielle Union and Amber Heard. Now, online perpetrators plan the same thing for Emma Watson. On the other hand, Watson has fought against such vile acts by defending the victims of the nude photo leak on Twitter.

"Even worse than seeing women's privacy violated on social media is reading the accompanying comments that show such a lack of empathy," tweeted Emma Watson on September 2.

Apart from defending women against the nude photo hack, Emma has spoken up about gender equality. For her campaign "HeForShe," the Hogwarts alumni gave an empowering speech about gender equality and that males should take part in the fight as well.

"How can we affect change in the world when only half of it is invited or feel welcome to participate in the conversation? Men -- I would like to take this opportunity to extend your formal invitation. Gender equality is your issue, too," stated Watson in her speech for the United Nations in New York City.

With regards to the photo hack and leak, FBI continues its investigation. Apple has also started an investigating team with regards to the iCloud photo service hack.
