Following the numerous incidents of celebrity hacking in the past few months, it appears that 'cyber geeks' have now targeted British actress Sienna Miller. Private pictures – including topless shots of the 35-year-old star – have reportedly been stolen and shared on the internet .

Miller was recently in news as gossip reports said she was spotted flirting with Brad Pitt. However, slammed the reports and said there was no truth behind the idle chatter.

Among the alleged leaked material are images showing Miller topless while wearing a mask on her face. According to the Sun, the latest breach is believed to be a work of celeb hackers, who allegedly cracked the passwords of cloud storage accounts and social media sites of the A-lister and her friends.

"Sienna will be devastated these pictures said to be of her fooling around have been put online by some weirdo," a source told the newspaper.

IBTimes UK has reached out to Miller's representatives for a comment and is awaiting response.

The hackers, illegally accessing celebrities' private picture and videos, generally trade the stolen material on the Internet for website hits and notoriety. As per reports, these hackers would use invite-only forum to share the files, before leaking them online.

"They sometimes post them online to show off and once they're online, it's hard to make them disappear again," the source adds.

With this latest privacy invasion, Miller joins the long list of celebrities, who too have become the victim of nude photo leak dubbed as "The Fappening 2.0". The photo hack mostly targeting actresses and female celebrities have so far exposed stars like Emma Watson, Amanda Seyfried, Katie Cassidy, Dylan Penn and a slew of WWE wrestlers including Paige, Summer Rae and Kaitlyn.

While the source of the leaks is still not clear, speculations are rife that it could be a result of online hacking – just as happened in 2014 Fappening, when 100-plus public figures were impacted by explicit leaks. As the breach continues, fears grow over more celebs and stars falling prey to the hackers.

So far, the nude photo scandal has received mixed response from the victims with some promising strict legal action, others choosing to ignore or deny the leak altogether.
