A new bug has surfaced in iOS 7.1 that appears to allow anyone with physical access to the device to delete the account of the owner at iCloud without having to type the password. The technique is not very easy, but that does not mean Apple will not have to fix the security gap.
According to the uploader of the demo video at YouTube, Miguel Alvarado, you can delete the account in the Apple cloud if you go to the settings panel, iCloud and select “Delete account.” At the same time, you should disable 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 you for a password but will delete your account. THE vulnerability is quite serious and should be addressed as soon as possible by Apple.
Apple will also have to address an iOS 7 problem that results in short battery life. So far, there is no indication that the company trying to fix it.
As it is known to those involved with the company, updates on such issues do not come as the release of new iOS, or a new device that always comes with a new iOS. Due to the severity of the vulnerability, we hope Apple will overcome it.
