"Downton Abbey" actress Jessica Brown Findlay is the latest victim of Sunday's large-scale hacking, dubbed the Fappening, that led to the leak of more than 100 nude pictures of celebrities.

Reports have it that 24-year-old Findlay, who is known for playing Lady Sybil in the ITV series, is seen performing a sexual act on an unidentified man, besides appearing naked in a number of videos.

The actress' representative confirmed that it is her in the video, but added that Findlay will not be making a comment as a criminal investigation is ongoing.

The FBI and Apple have launched an investigation on Monday after someone hacked into Apple's iCloud online data storage to steal explicit pictures of A-list celebrities.

"We take user privacy very seriously and are actively investigating this report," said Apple spokeswoman Natalie Kerris, according to the Re/code website.

Laura Eimiller, spokeswoman for the FBI in Los Angeles, told the Los Angeles Times that the agency too is looking into the matter. "The FBI is aware of the allegations concerning computer intrusions and the unlawful release of material involving high profile individuals, and is addressing the matter," she said.

Meanwhile, the hacker responsible for the leak noted that he is disappointed by the money received for these pictures.

"People wanted s*** for free," the hacker wrote on 4chan, according to the Independent. "Sure, I got $120 with my bitcoin address, but when you consider how much time was put into acquiring this stuff (i'm not the hacker, just a collector), and the money (i paid a lot via bitcoin as well to get certain sets when this stuff was being privately traded Friday/Saturday) I really didn't get close to what I was hoping."

The hacker also claims to be in possession of a "short" sex video featuring Jennifer Lawrence, and he is reportedly accepting Paypal donations for the video, reported Metro.

"I know no one will believe me, but i have a short lawrence video," the hacker wrote. "Is way too short, a little over 2 minutes and you only get to see her boobs.

"Anyways, if somebody wants it let me know how i can upload it anonymously (i dont want the FBI over me, and you dont wanna know how I got this video)."
