Leslie Jones' personal website has been taken offline after it appeared hackers posted her driver's licence and passport and photos of the actress and comedian.
The hackers also appeared to have inserted images on JustLeslie.com of the dead gorilla Harambe and the Ghostbusters actress posing with such stars as Rihanna, Kanye West and Kim Kardashian West.
Saturday Night Live star Leslie quit Twitter last month then later rejoined after facing racial slurs, obscene photos and comments about her appearance. She called on the social networking service to do more to curb harassment on the platform.
A spokesman for Leslie didn't immediately respond to messages seeking comment.
Ghostbusters filmmaker Paul Feig called it an "absolute outrage" on Twitter.
