Has anyone done research yet on the ability to control low level modems using a GSM tower? It seems likely commands like these could be executed over the air.
Also I see they got access to /proc which I assume is also access to memory via /proc/pid/mem?
I've done a little, and from what I saw AT wasn't available over the air, but more scary stuff like "update your firmware to this unsigned binary" and stuff were. Testing was with SIM[8/9]00. Albeit those are simpler basebands than you would find in a smart phone. They have a "lol, what's a OS/mmu" view of the world.
