Quoting Andrew McGlashan (andrew.mcglashan@affinityvision.com.au):
Heck, baseband ..... IME .... we are so lost these days, when we should be enjoying a far better and infinitely safer computing environment without needing to revert to flip phones and ancient pulse dialer phones (neither of which are as safe as they should be either fwiw); which the powers that be couldn't care less about ... AU legislation for instance (both direction and current situation).
Heh. My attitude with my flip phone (Motorola RAZRv3, with a spare in my kitchen drawer ready for the SIM when this one dies) is that, absolutely, it could have been remotely compromised by the GRU, or these days by practically anyone down to Benny the bookmaker, using its crummy baseband blackbox chipset. So, I am careful not to trust it in any way, e.g., there's no data worth stealing on it, I assume all its channels for communication are insecure, and I authenticate anything on it I see or hear through other means. Reminds me: There was a hardened Android project that did a pretty hardheaded examination of all security risks on Android mobile devices, including the baseband threat. One of their conclusions was that, if you really wanted to be serious about device security, you should have hardened Android running on a wifi-only tablet, which you connect via USB cable to a separate mobile gateway ('modem') hardware widget. That being the only way they figured you could (at that time) ensure decent isolation of the phone processor from the baseband processor.
I do run my own XMPP server, but rarely both with it.
I used to do that, too, and it was fun. I should try it again.
