.. and by unfettered, we mean it has DMA access to the application processor. It's not a hook or an API call or some functions it can call - it has low level bit for bit access to manipulate the CPU that your OS (like android) runs on.
Further, your carrier (verizon, att, whatever) can push OTA updates and commands straight to baseband via the radio, bypassing the CPU and OS (like android) and manipulating the phone on a low level bit by bit basis.
Even the most well secured, rooted, reloaded phone has every piece of it totally owned by the carrier, via the baseband processor.
Yes, that includes your photos.
- ricw 13y agoDMA has security modes, implemented by pretty much every standard baseband chip in use today (Qualcomm, Infineon, you name it). In the oldern days baseband exploits were used to crack iPhones. As far as I'm aware of, this hasn't happened in the last two generations of iPhones. So no, you do not have unfettered access to all the data, only the "baseband" segment, unless you manage to hack your security setting for the baseband. For which you first have to hack the Primary OS. I hope you get the theme..
