That number is readily available by any base station that communicates with the phone.

In the case of the authentication, for example, they found that the systems use passwords that are generated in part using a public identifier-that is, the IMEI, or the cell phone’s serial number. The 7.0.4 version of the software, which Apple released in November, partially solved the issue. Among iOS devices, they found that only iPhones offered by Sprint and running an operating system prior to version 7.0.4 were vulnerable. Two phones that provided the highest level of exploitation were the HTC One M7 and the Blackberry Z10.

In many cases, they could also control firmware updates.Īnd even the phones that use only the most basic management system have memory corruption vulnerabilities that would still allow a hacker to execute code or install malicious applications, they found. But at a minimum, every device they examined would allow an attacker to change all of the cellular network functionality. The more features the management tool offers the carrier, the more an attacker can do as well. "Whether you have the number 1 programmed for your mother, it would then do what we choose.” "Pretty much whatever number … if we programmed it, when you dial it, it would do whatever functionality we programmed it to do," Solnik says. But Solnik found this feature can be used to redirect any number phone numbers also can be programmed to launch an application. For example, Verizon might program its phones so "299" dials customer service. Carriers typically use this feature to program shortcuts to their own phone numbers. Others include a call redirect function that can direct the phone to a specific phone number. Carriers also can modify settings and servers for applications pre-installed by the carrier-something hackers could exploit to force the phone to communicate with a server of their choosing.įurthermore, some of the systems can monitor the web browser's home page and in some cases retrieve synced contacts. The systems give the carrier the option of making these changes with our without prompting the consumer.
More significantly, they've found systems that allow the carrier to identify the applications on a handset, as well as activate or deactivate them or even add and remove applications.

They've also found systems that allow the carrier to identify nearby WiFi networks, remotely enable and disable Bluetooth or disable the phone's camera. Solnik says they found that some phones have features for remotely wiping the device or conducting a factory reset, altering operating system settings and even remotely changing the PIN for the screen lock. From these guidelines, each carrier can choose a base set of features or request additional ones. The management tools are implemented using a core standard, developed by the Open Mobile Alliance, called OMA device management.
