A new bug appeared in iOS 7.1 which seems to allow anyone with physical access to the device to delete the owner's account at iCloud without having to type the password. THE technique it's not very easy, but that doesn't mean Apple shouldn't fix it security gap.
According to YouTube demo video uploader Miguel Alvarado, you can delete your Apple cloud account by going to the settings, iCloud και επιλέξτε “Διαγραφή λογαριασμού.” Ταυτόχρονα, θα πρέπει να απενεργοποιήσετε το Find My iPhone. The phone will display two dialog boxes but you will not use either of them. Immediately after and while your device asks for the password to proceed with deleting your iCloud account, turn off the phone.
After reboot, reopen the settings window and choose to delete the account.
This time, iOS will not ask for your password but will delete your account. Vulnerability is serious enough and should be dealt with as soon as possible by Apple.
As is known to those who deal with the company, the updates for such issues they don't come near the release of a new iOS, or a new device that always comes with a new iOS. Due to the severity of the vulnerability, we hope that Apple will go above and beyond.
