- belorn 13y agoTo my understanding, the GSM firmware can be remotely updated through the GSM protocol. If such firmware update has access to the memory, it can then do any type of exploits including accessing the microphone. Through I suspect there are much easier methods, such as attacking the software stack itself like: https://www.usenix.org/system/files/conference/woot12/woot12-final24.pdf https://www.usenix.org/system/files/conference/woot12/woot12...
- tmzt 13y agoUnless you block, modify or disable certain daemons, any Android device can be told to update the radio firmware by the carrier. This is called FOTA, firmware over the air. As an aside, when I was porting Linux to the Motorola Q I realized I could easily turn off the display and key backlight and turn on the microphone and camera though the sysfs,this would appear to anyone as if the phone was off but I could remotely control it (SSH tunnel) and capture audio and video. The only problem would be the heat, but someone would likely assume it was used for a while before powering it off. This without any low-level firmware change, just booting GNU/linux ;) from HaRET.
