Notes on lab session


I did not find the Bluetooth Specifications and Profiles Book readily on Google, so for your convenience I put these two documents up here. The profiles book, together with the OBEX specification should be the sources to use when trying to figure out what these vulnerabilities were that Christian was talking about this morning in the lecture. As far as I understand, the mentioned attacks exploit the fact that in some profiles you can use functions which are not specified to be in there, but which were actually defined for other profiles which are more heavily protected. (e.g. you need to connect to the device, pair with it, enter a pin, stuff).

Preparation for the WiLDing session

In order to get the most out of our WiLDing experience, you should have a few tools available and basically set up when we start. For *nix, you should probably get Kismet in version 4.x, since it supports many more chipsets. Also, you should make sure that your WLAN card supports monitor mode, since Kismet works completely passively. For Windows, you might wanna try Netstumbler. In case you have other tools available you feel more comfortable with, please feel free to use those.

You need to install/compile Kismet with ImageMagick support enabled in order to use its map drawing feature. For this you should also get gpsdrive and gpsd, which comes bundled with it.

Kismet creates quite a few files representing discovered networks in different formats, so you might wanna have a seperate directory to keep those. Please also note that Kismet needs to be run suid root in order to switch your card into monitor mode. If Kismet does not support your special chipset, try to do the switch manually or grab another card from the lab or somewhere else.

I will try to get maps for this region to use with the map drawing feature. Hopefully they will be put on our file server. Right now gpsdrive is still bugging me with less verbose error messages.

UPDATE: I got maps which should be about right for us. I got one for a scaling factor of 15000 which should cover most of Aachen aswell as one of the city centre at the scale of 10000. Get those either from the links provided or using gpsdrive directly (take the expedia server). The coordinates I used are:

Lat: 50.775 Long: 6.082

In case you are going for really strange routes, you might wanna play with the coordinates (just as a reminder: to go north, increase Lat; to go east, increase Long).

You also need mySQL to get Kismet and gpsdrive to play together. Use the provided .sql file (and maybe edit it beforehand) to set up the geoinfo database.

I4 has asked us to provide our results to their research team, so please keep your data (preferrably in csv format) and we can collect them afterwards.
