I immediately thought of @tinker - https://www.csoonline.com/article/3331989/security/vulnerabilities-found-in-building-access-system-used-by-schools-government.html

I'm thinking of doing a podcast with an InfoSec focus. Would be 15-20min episodes. Debating topics still.

I'm leaning toward a podcast where we talk through various things folks getting into InfoSec would need to know. Grow to include the infinite number of topics out there. Helpful for newbies & experts & leaders. Not just "What is AV" but "Why does AV matter". Periodically bring on experts and vendors to talk about their expertise and dive deeper into specific topics.

Thoughts?

So #Signal is supposed to be installed on a smartphone before you can use it on desktop? Unofficially, the desktop version is perfectly capable of creating new accounts. All you need is a number to receive an SMS or voice mail. Here is how.

@tinker As Quectel, Huawei, SIMCom, ZTE are all Chinese companies, I would try my best to keep myself away from their products for the sake of security and openness.

If you already have a Sixfab Raspberry Pi 3G-4G/LTE Base Shield V2, Sierra Wireless AirPrime MC series (Qualcomm-based, support voice call with newer firmware) seem like a fit.

According to the document below, all the functions you need should be available through USB.

@tinker SparkFun has a variety of cellular things - https://www.sparkfun.com/search/results?term=cellular (I don't have any personal experience with them though).

@tinker The Pyra project is not dead yet. It's not super open hardware at this point (old TI OMAP5, Gemalto Cinterion baseband), though it's not impossible to switch to a different CPU in the future. Nikolaus Schaller (who was involved in the GTA phones) just announced he's been working into combining the Pyra CPU board and a baseband for a GTA followup project: http://lists.goldelico.com/pipermail/community/2019-January/001935.html

Everything is moving at glacial speed though - minimal funding results in lots of compromise solutions...

Big thing...

Does anyone know of a hardware module (pi hat, arduino shield, usb dongle) that interfaces with Quectel basebands or other basebands AND provides voice/sms (VoLTE or similar).

Sixfab shields are great, but they don't take advantage of voice functionality.
