Apple Takes Steps To Prevent iCloud Hacks
Apple has said the company will take additional steps to prevent hackers from accessing iCloud accounts after dozens of celebrities had nude photos stolen and posted online.
Chief executive Tim Cook told the Wall Street Journal that new alerts will inform a user when someone tries to change a password or restore deleted information on the data storage system.
Actresses including Jennifer Lawrence and Selena Gomez were among a host of celebrities who had pictures leaked on the internet.
Mr Cook said that hackers had correctly guessed security questions to change victims' passwords, or employed phishing techniques to convince their victims to hand over their Apple IDs and passwords.
He also stressed that none of the IDs or passwords were leaked from Apple's servers.
He told the newspaper: "When I step back from this terrible scenario that happened and say what more could we have done, I think about the awareness piece.
"I think we have a responsibility to ratchet that up. That's not really an engineering thing.
"We want to do everything we can do to protect our customers, because we are as outraged if not more so than they are."
He added that a new iOS 8 operating system would encourage people to use two-factor authentication, where a user is required to have two of three key bits of information to access an account - a password, a four-digit one-off code or a long access key given when they sign up for the service.
That system update is due later in September and will cover access to iCloud accounts.
It comes after the FBI said it was investigating the leaking of the nude photos on an online bulletin board in the US.
A list of those who have allegedly been hacked is reported to have appeared online, and contained more than 100 names including Kate Upton, Cara Delevingne, Aubrey Plaza, Cat Deeley, Kelly Brook, Kim Kardashian and Rihanna.
