GSMdump is a studie project at the Hochschule der Medien in Stuttgart. The project takes a look at the
GSM protocol. It’s goal is to dump and analyse real
GSM-Traffic from an own
BTS and also from the four German network-provider with the use of an
Here you will find a
Live-CD based on Ubuntu 10.04 (i386), that contains all necessary tools to dump and analyse
GSM traffic. At the moment it is only possible to dump the unencrypted downlink from the
BTS to the
MS. The CD contains the following preinstalled tools:
- GNU Radio
The software is allready configured, you only have to boot it, plug-in your
USRP an start some easy-to-use scripts.
HowTo for the Live-CD
About the CD
Live-CD is based on Ubuntu 10.04 (i386). Some not needed tools were removed from the CD to get some space and keep the image smaller than 700 MB.
All necessary tools to dump and analyse
GSM traffic are allready installed and configured. These include:
- GNU Radio (version 3.1.2)
- Wireshark (revison 26844 and version 0.99.5)
- Download the ISO image and copy it to a USB drive or burn it on a CD
- Boot your PC from this CD
- Plug in your
USRP(the system is configured to speak to the
USRP, it should not be necessary to do more here)
- Start a terminal
gsmdump.sh(this will scan all
BTSand show you a summary)
~/Desktop/gsmdump you will find some usefull scripts on the CD. These are in the PATH of the system, so you can start them from every directory.
The scripts have an English help. You can start them with the parameter
-h and should get an overview what this script is for and how to use it.
Some important scripts are:
gsmdump.sh: will scan all
BTSand show you a summary. You will find the result in a new folder named like the date and time the script was started. The result includes dumps in
Wiresharkformat and info files about the found provider,
gsmlive.sh: starts a live capture.
Wiresharkin version 0.99.5 (linked as
gsmshark) will be started and capture the
capture.sh: will dump the raw data from the air
analysecfile.sh: will create a result like from
gsmdump.sh, but will use a raw file from
- gsmdump.iso, the
Live-CDbased on Ubuntu 10.04 (i386) with GNU Radio,
Wiresharkand a lot of usefull scripts installed (version from 25.08.2010).
Please note that the versions of the software used for GSMdump are outdated. I recommend you to setup your own workstation with the newest available software. If you still want to get the ISO, you will find it here.
