Emma Watson is being threatened by hackers just days after making an emotional plea for sexual equality at the United Nations.

In her role as a UN Women Goodwill Ambassador, the British actress and Harry Potter star gave an impassioned speech at UN headquarters Saturday, inviting men and boys to join the fight to end gender inequality:

"I want men to take up this mantle," Watson urged. "So their daughters, sisters and mothers can be free from prejudice but also so that their sons have permission to be vulnerable and human too."

Then, hours after Watson told the UN it's a woman's right to make choices about her body, someone created a website threatening the actress by name.

Ominous message on 4chan

Online perpetrators have created a website called Emma You Are Next with a countdown clock ticking down to something happening in about 4 days.

While the message doesn't say what happens when time is up, it was posted on 4chan, the same image-sharing site that leaked nude celebrity photos on Saturday, and earlier this month.

The words "Never Forget, The Biggest To Come Thus Far" appear on the page below a picture of Watson apparently wiping away a tear.

Watson hasn't addressed the threat publicly. But after the first batch of photos was leaked, the actress expressed her outrage on Twitter, writing: "Even worse than seeing women's privacy violated on social media is reading the accompanying comments that show such a lack of empathy."
