- 3. 3 When Android is not enough? ¡ñ Completely custom userspace ¡ñ Long term support? You'd wish. ¡ñ Sure, it's open... but ¨C Is your Android device open as well? ¨C Can you influence its development? ¨C Can you use it with FLOSS only? ¡ñ There is Replicant. But... is it compatible with your phone? ¨C Can you replace it? No, I don't mean ?modding¡±.
- 7. 7 Not really. ¡ñ Repeating Android mistakes with undocumented, closed and locked-down hardware ¡ñ Limited paradigms ¡ñ Customer friendly ¨C Yes, sometimes it can be a flaw. ¡ñ Not completely FLOSS!
- 8. 8 Hardware
- 9. 9 The Hardware Problem ¡ñ I'm the admin of my PC. Why can't I be the admin of my phone as well? ¡ñ We don't use App Stores on Pcs. Why should we need them on phones? ¡ñ We can choose from hundreds of systems to install on PC. Why can't we do that on mobiles as well?
- 10. 10 The Hardware Problem Does a cellphone really differ so much from your average laptop? It doesn't. It's just smaller and more integrated.
- 11. 11 The Hardware Problem ¡ñ Lack of documentation ¡ñ Closed components ¡ñ Porting ¨C the neverending story ¡ñ Upstream? In your dreams. ¡ñ When you have to break into your own device in order to use it as you wish, something is completely wrong!
- 12. 12 The Wise Quote Time ?The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.¡± George Bernard Shaw

- 39. 39 Privacy
- 40. 40 Open baseband? ¡ñ Unfortunately, it's not going to happen for both economical and legal reasons. ¡ñ Basebands are cryptographically locked and any change in their firmware results in revokation of their certification, rendering them illegal to use in public networks.
- 41. 41 OsmocomBB ¡ñ Open baseband firmware ¡ñ Runs on TI Calypso (the same as in GTA01/02) ¡ñ Illegal to use as a phone outside the lab ¡ñ http://bb.osmocom.org
- 42. 42 Open baseband? ¡ñ However, open baseband does not fix the privacy problems.
- 43. 43 The threats ¡ñ Tracking ¨C Trilateration based (IPL, OTDOA, E-OTD, U-TDOA) ¨C GPS-assisted (RRLP) ¡ñ Eavesdropping ¡ñ Data leakage ¡ñ Security bugs in firmware ¡ñ Direct access to main RAM
- 44. 44 Not solvable ¡ñ Eavesdropping of calls ¡ñ Eavesdropping of Internet connection ¡ñ Trilateration while connected to the network It can (and does) happen outside of the device or is necessary for it to function. Aside from encryption, there's nothing we can do against it.
- 45. 45 Neo900 concept ¡ñ Counter-surveillance rather than audit and trust ¡ñ Everything not 100% in control is considered rogue ¡ñ Rogue stuff is sandboxed and constantly monitored
- 47. 47 Neo900 design ¡ñ If the modem is compromised, the main system remains safe use the encryption, Luke ¡ñ If the modem is supposed to be off, but it isn't ¨C we know that and can react accordingly ¡ñ If the GPS is in use when not requested ¨C we know that but the antenna will be disabled :) ¡ñ If the modem tries to record audio when not requested ¨C we know that but it won't be able to do it :)
- 48. 48 Neo900 design ¡ñ When modem act badly, user is notified and automatic hard reset via emergency_off line is applied.
- 49. 49 Neo900 concept ¡ñ This way, when something fishy is going on, software kicks off an alarm to make user do efficient measures to stop the threat: ¨C Removing the battery ¨C Destroying the device ¨C Hiding it under the seat in bus and leaving ¡ñ With basic solutions like external power switch, user is not aware that his device has been tampered with.
- 50. 50 Neo900 design ¡ñ Our monitoring approach can also reveal some ?rogue¡± activities from outside ¨C like packet-storms on airports. https://www.schneier.com/blog/archives/20 14/04/gogo_wireless_a.html#c5459667
