Smart phones and other portable devices are increasingly used with Microsoft Exchange to allow people to check their corporate emails or sync their calendars remotely. Exchange has an interesting relationship with its mobile clients. It demands a certain level of control over the devices, enforcing policy such as password complexity, screen timeouts, remote lock out and remote wipe functionality. This behavior is usually accepted by the user via a prompt when they first connect to Exchange. However, the protocol for updating these policies provides very little in the way of security and is quickly accepted by the device, often with no user interaction required. In this talk we will focus on the remote wipe functionality and how a potential attacker could abuse this functionality to remotely wipe devices that are connected to Exchange. By impersonating an Exchange server and sending appropriate policy updates through a simple script we are able to erase all data on devices remotely without any need for authentication. The presentation will explain how this can be accomplished and show proof of concept code for Android & iOS devices. There will be demos.
