Osmocom Trx with OpenBTS
by Hassan Mourad 24 Feb '14

24 Feb '14

Hi Guys, So I was trying to use my osmocom phone as a transceiver for openBTS. I followed the procedures indicated in this link " bb.osmocom.org/trac/wiki/Software/Transceiver" and was able to successfully load trx.compalram.bin on the phone, connect openBTS to it and sync the clock to the strongest cell around I got the output attached from openBTS For some reason however when I search for the network I am unable to find it. I can not figure out what exactly is going on here and I was wondering if any one can help One thing to point out is that I was never able to set the below value to the suggested value as it was not in OpenBTSs configuration options. I am not sure if this has been deprecated or replaced by any other options GSM.CellSelection.Neighbors = (set to empty string) Any help would be appreciated Starting the system...

RE: Welcome to the "baseband-devel" mailing list

Hi all, I am new on this open source community. I am a looking for a "basic" open source code that would be compliant with the UMTS standard. By basic I mean, I would simply try to manipulate my RTL2832u-based DVB-T dongle (on a R-PI) to make it reaching let's say the neighborhood cell IDs plus their corresponding receive power. Maybe I am stupid, but despite the time I have spent on the websites and while there is a lot of very interesting stuffs related to GSM/GPRS/LTE standards: I could not find anything compliant. Even AT command would sound good to me in a first time. Thanks for your answers or even for any clue, Cheers, Sébastien

Re: [Openbts-discuss] OpenBTS / E100 & GSM attacks.
by Hacker Fantastic 14 Feb '14

14 Feb '14

Hi Michael, It is my intention to share an image and speed the process up for other researchers interested in GSM attacks and building simulations in their labs. 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.

OpenBTS / E100 & GSM attacks.

Hi all, My first attempt to send this email didn't appear to succeed so I am re-sending without attachment. Here is a copy of some slides https://github.com/HackerFantastic/Public/blob/master/presentations/mwri_la… wrote for a presentation on security weaknesses within GSM. I used an Ettus E100 to develop a malicious BTS and GSM related attacks in a Faraday cage and presented on how these attacks work to better understand them for defensive purposes. I was able to use the E100 as a generic IP-router after I cross-compiled a new kernel with netfilter enabled and also I had to recompile a number of the packages such as Asterisk to enable ODBC and improved SQLite support, I also had to make some changes to Python and its modules. I used GNURadio 3.6.4 and I had to compile a specific version of the OpenBTS code as the recent transceiver application did not function with the E100. I was able to get the E100 to work as a GSM/GPRS router and do real-time call placement etc. I got it to function with real-time support and wrote a small script to provision new devices by watching the syslog and adding to the SQLite database. I also used osmocom-bb to do things like use gnuplot and graph the channel usage although the code is extremely ugly! I took RSSI measurements over a period of time into images and then tied them together for a movie, it isn't quite realtime but it makes pretty graphs. I mentioned how you could implement the MS side of the GSM stack using the osmocom project and as such am sharing the slides with the osmocom list. Just goes to show how mighty things come in small packages! Hope this material is useful to others on the list who may also be trying similar experiments. I ended up creating a firmware image that could be used to dd and boot an E100 but at this time I do not plan on hosting it for download unless there is sufficient interest. If you need it for some reason drop me an e-mail. Here is an example of the output of the greedyBTS script. As an example my code plays "Rick Astley - never going to give you up" when a user places a phone call and they have been provisioned with service. All of this work was done in a faraday cage which I obtained from Ramsey electronics which had very good frequency attenuation graph from 0mhz all the way to 1ghz. root@usrp-e1xx:~# ./launch.sh Launching asterisk Launching HLR SMS Launching OpenBTS Launching Greedy BTS.. 888 888 d8 e88 888 888,8, ,e e, ,e e, e88 888 Y8b Y888P 888 88e d88 dP"Y d888 888 888 " d88 88b d88 88b d888 888 Y8b Y8P 888 888b d88888 C88b Y888 888 888 888 , 888 , Y888 888 Y8b Y 888 888P 888 Y88D "88 888 888 "YeeP" "YeeP" "88 888 888 888 88" 888 d,dP , 88P 888 pDK++ "8",P" 888 [+] Current CELL configuration [-] ========================== [-] Shortname: 'Noone' [-] MCC: 901 MNC: 70 C0 ARFCN: 51 [-] LAC: 3336 ARFCN's: 1 BAND: 900 [-] [-] Radio Power [-] =========== [-] RxGain: 47 MaxPower: 10 MinPower: 0 --> help [+] HELP SCREEN [-] dump imei - lists all identified IMEI [-] dump assoc - lists all IMEI+IMSI associations [-] dump imsi - lists all identified IMSI [-] dump save - store a record of all identities [-] start service - provide service to IMSI & log traffic [-] show service - show all provisioned phones [-] stop service - deletes an identified IMSI from HLR [-] calls - provide call collection statistics [-] sms - provide sms collection statistics [!] gprs - provide gprs collection statistics [-] cellconfig - configure cell parameters for spoofing [-] cellinfo - dump information on current cell [-] cellshow - list short codes for common cells [!] sounddial - play a sound recording to an IMSI [!] spoofsms - send a spoof SMS message to an IMSI [!] trunksetup - display current SIP trunk details [-] verbose - turn on real time tracing [-] exit - leave without shutdown [-] shutdown - bye! --> dump imei [+] Dumping seen handset IMEI [-] 1: IMEI359209002648230 [-] 2: IMEI358622002760070 [-] 3: IMEI350694801239040 [-] Total IMEI identified 3 --> dump imsi [+] Dumping IMSI capture results [-] 1: IMSI901700000002484 [-] 2: IMSI901700000002486 [-] 3: IMSI901700000002488 [-] Total IMSI identified 3 --> dump assoc [+] Dumping IMSI/IMEI association [-] 1 IMEI:358622002760070 used IMSI901700000002486 [-] 2 IMEI:350694801239040 used IMSI901700000002488 [-] Total associations 2 --> show service [+] Displaying all provisioned IMSI [-] 1: exten: 2100 user: IMSI001010000000000 [-] 2: exten: 2339 user: IMSI901700000002484 [-] Total subscriber count 2 --> stop service [+] Deleting IMSI from HLR [-] Enter IMSI: IMSI901700000002484 [-] Deleted IMSI901700000002484 --> help [+] HELP SCREEN [-] dump imei - lists all identified IMEI [-] dump assoc - lists all IMEI+IMSI associations [-] dump imsi - lists all identified IMSI [-] dump save - store a record of all identities [-] start service - provide service to IMSI & log traffic [-] show service - show all provisioned phones [-] stop service - deletes an identified IMSI from HLR [-] calls - provide call collection statistics [-] sms - provide sms collection statistics [!] gprs - provide gprs collection statistics [-] cellconfig - configure cell parameters for spoofing [-] cellinfo - dump information on current cell [-] cellshow - list short codes for common cells [!] sounddial - play a sound recording to an IMSI [!] spoofsms - send a spoof SMS message to an IMSI [!] trunksetup - display current SIP trunk details [-] verbose - turn on real time tracing [-] exit - leave without shutdown [-] shutdown - bye! --> dump imei [+] Dumping seen handset IMEI [-] 1: IMEI359209002648230 [-] 2: IMEI358622002760070 [-] 3: IMEI350694801239040 [-] Total IMEI identified 3 --> dump imsi [+] Dumping IMSI capture results [-] 1: IMSI901700000002484 [-] 2: IMSI901700000002486 [-] 3: IMSI901700000002488 [-] Total IMSI identified 3 --> dump assoc [+] Dumping IMSI/IMEI association [-] 1 IMEI:358622002760070 used IMSI901700000002486 [-] 2 IMEI:350694801239040 used IMSI901700000002488 [-] Total associations 2 --> dump save [+] Saving IMSI capture results [+] Saving seen handset IMEI [+] Saving IMSI/IMEI association [-] logfile stored as 'greedybts.log' --> shutdown root@usrp-e1xx:~# cat greedybts.log [-] 1: IMSI901700000002484 [-] 2: IMSI901700000002486 [-] 3: IMSI901700000002488 [-] Total IMSI identified 3 [-] 1: IMEI359209002648230 [-] 2: IMEI358622002760070 [-] 3: IMEI350694801239040 [-] Total IMEI identified 3 [-] 1 IMEI:358622002760070 used IMSI901700000002486 [-] 2 IMEI:350694801239040 used IMSI901700000002488 [-] Total associations 2 Kind Regards, Matthew
