I‘m glad to be back at #OBTS v8.0 with a talk about Apple‘s #C1 baseband and carrier profiles

objectivebythesea.org/v8/talks.htm...

So far, we haven't discovered this functionality, but we're in the early stage of researching the C1. The baseband likely contains such an interface, but it may be hard to access. If we have any interesting updates regarding that, I'll share them.

You install CellGuard with TestFlight or download the special build for jailbroken devices on our website: cellguard.seemoo.de/docs/install/

We've released CellGuard 1.6.0, our iOS app, to make use of the iPhone's internal baseband communication. The update enhances support for dual SIM, adds new #C1 packet types, automatic navigation to sysdiagnoses, and more: cellguard.seemoo.de/docs/changel...

Due to the decentralized @atproto.com architecture, researchers can also collect vast amounts of data from BlueSky. There's an interesting paper from April 2024 about this. It has a whole section about labelers. bsky.app/profile/gare...

Jiska's first lighting talk at #38c3 will show you how to get started with CellGuard to detect fake base stations

Thanks! You can rewatch the live stream recording with my talk at www.youtube.com/live/LKzJuEZ.... I guess at some point, there will also be a dedicated video. The slides are up on lukasarnold.de/pdfs/obts7-t....

It's great seeing students I've had the privilege to supervise deliver amazing talks at #OBTS - and for Lina it's even her first conference talk! Check out their recordings on YouTube: youtube.com/@objectiveseefoundation

Thanks for joining my talk about iPhone basebands at #OBTS #OBTSv7. It’s an awesome experience in Maui, and I’m looking forward to the rest of the conference. You can find the slides at lukasarnold.de/pdfs/obts7-t...
