The iCloud password was changed (and yes they know what to). Now the iPhone & iCloud won't - that is, can't - access any data until the 4-digit passcode is entered on the phone, which will self-destruct if 10 wrong codes are entered. After they enter the 4-digit passcode, then they can enter the new iCloud password.
