Replicant Developers Find Backdoor In Android Samsung Galaxy Devices
Developers working on Replicant OS, a free and open-source spin of Google's Android operating system, have claimed to uncover a backdoor into the device's file-system for several Samsung Galaxy mobile devices using the stock Android image.
Replicant developers found a back-door to be present in "most proprietary Android systems running on the affected Samsung Galaxy devices, including the ones that are shipped with the devices."
The Replicant developers' research finds "Samsung Galaxy devices running proprietary Android versions come with a back-door that provides remote access to the data stored on the device. In particular, the proprietary software that is in charge of handling the communications with the modem, using the Samsung IPC protocol, implements a class of requests known as RFS commands, that allows the modem to perform remote I/O operations on the phone's storage. As the modem is running proprietary software, it is likely that it offers over-the-air remote control, that could then be used to issue the incriminated RFS messages and access the phone's file system."
