Apple says hackers targeted celebrity accounts, not iCloud systems

Apple said that its iCloud systems have not been breached Tuesday and that thieves stole celebrity photos from Apple accounts by targeting individuals, rather than by breaking into the company's infrastructure.

"After more than 40 hours of investigation, we have discovered that certain celebrity accounts were compromised by a very targeted attack on user names, passwords and security questions, a practice that has become all too common on the Internet," the company said in a statement. Apple said that it is working with law enforcement to help identify who took the photos.

The statement indicates that the pictures -- nude images of several female celebrities taken in personal settings --  were stolen as a result of what's known as "social engineering" or "spear-phishing" attacks. In those attacks, hackers specifically target an individual user and attempt to trick account holders into giving up their passwords and usernames to break into an account.

Security researchers have also suggested that the attacks might have been the result of “brute force” attacks, where hackers try to break into accounts by repeatedly guessing hundreds or thousands of passwords in hope of guessing the right one.

The firm stressed that there's no indication that average iCloud users are at risk, but the company recommends that users always use strong passwords and use two-step verification.

"None of the cases we have investigated has resulted from any breach in any of Apple's systems including iCloud or Find my Phone," Apple said.
