A/V in the mobile marketplace is oft overlooked. This is a fatal flaw. but I would imagine it can only really offer a limited amount of protection, from the sort of things that shouldn’t(should the device be utilised sensibly) be much of an issue anyway.

I’m possibly showing my foil hat side here, but quite what is available in the marketplace with regards to A/V I’m unsure as I’m not simple enough to own portable spyware devices I have no particular physical control over so have not placed a great deal amount of research into.

Seems little point in protecting the phone from the software angle when the manufacturers are compelled to make it externally accessible in order to comply with things like CALEA, or not gain ability to enter the american marketplace. You can run whatever software you want, if the hardware is backdoored you’ll achieve little. The general trend towards SoC is great for power consumption, smaller devices etc but it’s also great for embedding hardware the user isn’t aware of. Hardware they won’t find without an electron microscope. Hardware that cannot be removed lest it interfere with critical functionality. A good previously published example here the OnChip 3G on post sandy bridge Intel i7’s. As a user you’re getting nowhere near that. It’s not for you to control the CPU, despite intel’s claims. Know of anyone that got a modem number with their CPU? There’s still people that don’t even know it’s there. Good luck diging it out of the chip without rendering it useless.

Even the ones the user is aware of are bad enough. For example, accelerometer, a standard feature of modern mobiles. For a little while I was confused. In what situation would I require to know which way up I’m standing? Taking into account this data was most likely not for me I couldn’t see a tactical advantage for some time. Turns out it’s a little more cunning with this. The accelerometers used are sensitive enough to pick up vibrations. Put the data through the right algorithym and you can pull back human speech. Classic misdirection. Most people would be busy watching the microphone.

With the IoT/IoE explosion provided by SoC you truely start entering a world where your phone is at risk and the assault vector is the toaster. Which was compromised by the washing machine, acting under instructions from the fridge passed down the power cable. Not even a faraday cage is enough to keep things secure anymore.
