The two photos allegedly depict Johansson in various stages of undress. An FBI official told Fox News, "The FBI is aware of the alleged hacking incident and is looking into it."
According to TMZ, Johansson directly requested the Bureau track down the culprits.
Fox News also reports that the FBI is already investigating whether other celebrities, including Vanessa Hudgens and Jessica Alba, had their email accounts hacked. According to TMZ, Hudgens met with law enforcement earlier this year about the hacking.
This is far from the first time a celebrity has had his or her privacy violated. Several years ago, ESPN reporter Erin Andrews was the target of a stalker who secretly videotaped her in her hotel room. That man, Michael Barrett, was later found guilty and sentenced to 30 months in prison.
Though it was never confirmed, hackers also claimed to have photos of actress Blake Lively several months ago. A rep for Lively quickly threatened legal action against anyone who posted or distributed the photos.
The cell phone hacking of Hugh Grant also caused a major uproar. Reporters for the now defunct British tabloid News of the World hacked into the film star's cell phone to listen to private messages. Grant had the last laugh when he secretly tape recorded one of the reporters admitting to the crime.
Not surprisingly, this latest scandal is causing an uproar on the Web. Over the past several hours, online searches for "scarlett johansson" and "scarlett johansson fbi" have both soared into breakout status.
