David A. Burgess dburgess at jcis.netLuca - I generally agree, for whatever it’s worth. To release a “turn-key” attack tool is irresponsible. Anyone qualified to actually do this kind of research can hack together their own attack experiments from available software without much trouble. — David On Feb 14, 2014, at 19:27, Luca Bongiorni <luca.bongiorni1 at studenti.unimi.it> wrote: > Hi Matthew, all, > > IMHO releasing such kind of image will just increase the number of script kiddies around that could mess with 2G networks (and that is a bloody seriously problem). > From my experience (e.g. after releasing some slides http://www.slideshare.net/iazza/dcm-final-23052013fullycensored ) I have always been asked to release sources/scripts/etc. which I have promptly denied. > The reason is pretty simple as you can imagine...

At this time there are code changes I want to expand upon before I do (predominantly cosmetic changes and making it more feature useful from the python script). I am also hoping that enhanced detection of fakeBTS attacks will be expanded upon by the osmocom-bb toolkit (the launch of the detection capability occurred in December 2013 at CCC.) which would sufficiently detect anyone attempting to use tools of this nature in an illegal way. Most of the work I did can be recreated from the slides previously provided. If you are interested in the E100 platform, I spent alot of time exploring its capabilities and re-compiling packages. I first started trying to build the firmware from scratch with some discussion occurring between myself and the firmware developer at Ettus, eventually it became easier to customize the firmware provided by Ettus - the most difficult change being a cross-compiled kernel to enable netfilter so that IP routing became practical thus allowing for GPRS capabilities. I also had issues with the OpenBTS 52MTransceiver application in the more recent commits as significant overhaul has begun on changing its capabilities. I eventually settled on r6718 version as this provided GPRS capabilities and also was the last version functioning with the 52MTransceiver application. Most of the firmware I had to rebuild from source including things not available in package repos such as libpcap, asterisk (w/ODBC), odbc, libsqlite and python to get the capabilities I needed to demonstrate the practical elements of a GSM attack from an embedded device. I will be releasing the firmware image as soon as I tidy up some of my python code and detection tools become more effective. If you do really need the image for some research purpose then please e-mail me directly and I will gladly share a copy with you providing I can understand better your requirement for needing an off-the-shelf attack tool for GSM. >> >> Kind Regards, >> Matthew >> > > The information contained in this message may be CONFIDENTIAL and is intended for the addressee only.
