I’ve just attended Bossa Conference 2010 in Manaus, Amazonas, Brazil. Thanks again to the Instituto Nokia de Tecnologia (INdT) for holding this amazing conference. I’d say it’s somewhat like FOSS.in, but with less people and a more relaxed atmosphere.
I gave a talk about “Security in Mobile Devices” and went very well although I refactored my slides just shortly before I gave it and I expected more fuckups. But the people apparently enjoyed it and I got lots of interesting feedback. You can find my slides here.
If you’ve been there and want to follow-up, you might find the Maemo Wiki on Security interesting. I recommend to read through the stuff that Collin Mulliner did, on i.e. NFC or the iPhone. Also the things that he did together with Charlie Miller are worth reading, basically fuzzing the Operating System by pretending to be the modem which produced interesting results. But there is more work to be done which I am convinced will give more interesting results in the future. Maemo on the N900 apparently doesn’t talk via a serial line to the modem but rather via PhoNet, making it even more interesting to fiddle around with the low level GSM stack.
As for policies and statistics, Symantecs Ollie Whitehouse wrote some interesting articles such as this or that. Other, more technical papers include Yves Younans Filter Resistant ARM Shellcode or some guys proposing Kirin to extend the Android security model. For a more general overview, have a loot at a good Android link list.
As for the rest of the conference, I felt that it was a bit shallow content-wise probably because of all that Qt stuff that was presented. But in fairness, they had to bring it since it’s going to be used by Maemo Meego. Anyway, I enjoyed it pretty much, because the people were all open and interested and I had good conversations. And good food 😉
