Make sure you see the "return" key before inputting your iCloud password. If it says "Go" instead of "return" you risk sending a hacker your iCloud password
Be on the look out for a new iCloud password hacking attempt. Features in your iphone/ipad's native email app make it possible to receive an email that prompts for what looks like a legitimate dialog box requesting your iCloud username and password. In reality, the dialog box is an internet form that can send your iCloud username and password to the hacker.
Currently, the best defense against this exploit is knowing that it exists. The best way to tell if the password box is legitimate is to look at the lower right of your keyboard. If it says "Go" in the corner that's BAD! DO NOT INPUT YOUR INFO. If it says "Return" you should be fine. "Go" indicates it will be sending that information outside your device.
