Hackers probably got naked photos of stars by exploiting password weakness
Naked photos of celebrities probably stolen due to slack security or hackers getting their email addresses and using 'forgot password' link

Apple and the FBI have pledged to investigate the alleged security breach of the tech giant's cloud data storage service, which is believed to have led to the leaking of nude photos of dozens of celebrities this week, including Oscar winner Jennifer Lawrence.
But experts say that the case is less likely to be a case of a full-blown hacking of the popular iCloud service, than the leak or guessing of email and password combinations.
"We take user privacy very seriously and are actively investigating this report," said Apple spokeswoman Natalie Kerris.
The FBI has also joined the hunt, other US reports said. "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," Laura Eimiller, spokeswoman for the FBI in Los Angeles, said.
"Any further comment would be inappropriate at this time," she added.
