‫ Samsung Galaxy devices may have backdoor to user data, developer says

According to "cnet", Samsung's Galaxy devices might have a built-in security flaw that could allow for "remote access to data," a developer claims.

The folks behind Replicant, a free and open-source OS that aims to replace proprietary Android components with free alternatives, claim to have discovered a flaw in certain Samsung devices that allows for access "to read, write, and delete files on the phone's storage." In addition, the developers said that the flaw has "sufficient rights to access and modify the user's personal data."

In a blog post detailing the issue on Wednesday, Replicant developer Paul Kocialkowski said the trouble resides in the use of two processors in mobile devices. The applications processor runs the main operating system, while another, baseband processor, is used to handle communications to and from the device. The issue with the baseband processor in Samsung's devices, Replicant argued, is that it's using a proprietary Samsung software to handle all the communication -- and that software allows for a backdoor to user data.

"Provided that the modem runs proprietary software and can be remotely controlled, that backdoor provides remote access to the phone's data, even in the case where the modem is isolated and cannot access the storage directly," Kocialkowski wrote.

According to Replicant, the Nexus S, Galaxy S, S2, and S3, and Galaxy Tab 2 10.1, among other Samsung devices, are affected by the issue. It's worth noting that Replicant's announcement might also be somewhat self-serving: the company said in a blog post that its free alternative would mitigate the issue.
