Earlier this week, a number of iOS and Mac users reported iPhones, iPads, and Macs being remotely locked by hackers who then demanded a ransom for their recovery.
ZDNet reports that Apple has issued an official statement denying that iCloud itself was hacked.
A growing discussion thread on Apple's support forums is following the issue.Apple takes security very seriously and iCloud was not compromised during this incident. Impacted users should change their Apple ID password as soon as possible and avoid using the same user name and password for multiple services. Any users who need additional help can contact AppleCare or visit their local Apple Retail Store.
