The probe stems from nude photos of Vanessa Hudgens that were recently leaked online, reports the New York Daily News.
According to TMZ.com, the federal investigators met Hudgens Wednesday to discuss her latest nude photo scandal and believe she might be the latest victim of a notorious hacker crew that has targeted scores of celebrities, including Scarlett Johansson, Ali Larter, Busy Philipps and Miley Cyrus.
A source told the website that one ringleader had fingerprints on every job and the primary motivation appeared to be the thrill and challenge - not money.
The new round of Hudgens' photos surfaced on the Internet Monday after similar full-frontal nudes appeared online in 2007 and 2009.
Hudgens, 22, is seen kissing 'Zoey 101' actress Alexa Nikolas in one of the new photos.
"Vanessa is deeply upset and angered that these old photos, which were taken years ago, continue to resurface," Hudgens' lawyer Christopher Wong said in a statement.
"It is particularly disturbing that whoever got hold of these private photos seems to be intent on illegally leaking them out over a long period of time," he said.
"We are actively working with law enforcement to determine who is responsible and hold them accountable for their actions," he added.
The alleged raiding of her gmail account comes as the 'High School Musical' star prepares her return to the big screen in her new film 'Sucker Punch'.
