Special phone codes are dialed to initiate certain actions. For example, USSD codes in GSM networks allow a user/phone to send commands to the phone operator network, which will result in an answer sent back to the user/phone. Android offers a mechanism that allows any application or web browser to automatically dial special codes and execute functions. Hackers have exploited this mechanism to create functions that will reset the device to its factory settings or call expensive phone numbers, causing the user to lose all data or incur excessive bills.
To protect against this vulnerability, Sophos Mobile Security will:
· Register as the receiver for all special codes
· Prompt the user with a notification when a special code is accessed, giving the user control over the execution of the special code.
· For all normal telephone calls, the Sophos Mobile Security app will intercept the dialing process and let these numbers be dialed immediately
In addition to this new functionality, Sophos Mobile Security provides protection against malicious apps, protects data in case of loss and theft and guides users to have safe settings on the device. It can be downloaded for free from Google Play at: https://play.google.com/store/apps/details?id=com.sophos.smsec
