h2. Overview This is a collection of tools for the assessment of mobile network security. It includes: * *[[SIMtester]]* Finds configuration bugs in SIM cards * *[[GSMmap-apk]]* Android application that collects 2G and 3G network traces from Samsung Galaxy phones * *[[xgoldscanner]]* Linux application that collects 2G and 3G network traces from Samsung Galaxy phones * *[[catcher catcher]]* Collect evidence of 2G fake base station activity (requires Osmocom phone) The tools are included in the *GSMmap-live* system, which auto-submits data for analysis at "GSMmap.org":https://GSMmap.org ***** h2. SIMtester Assess SIM card security in two dimensions: * *Cryptanalytic attack surface.* Collect cryptographic signatures and encryptions of known plaintexts * *Application attack surface.* Generate a list of all application identifiers (TAR) TARs and find "unprotected" (NSL=0) applications * *Spec. compliance* h3. Requirements: * Java (TODO: Which Java edition/version?) * PC/SC reader –or– * Osmocom phone h3. Download Pre-compiled .jar TODO Source Code TODO Live System TODO h3. Instructions # Download # unpack # run: TODO call * TODO command line parameters h3. Mailing list A public mailing list for announcements and discussion can be found "here":https://lists.srlabs.de/cgi-bin/mailman/listinfo/simsec . ***** h2. xgoldscanner Actively collect 2G and 3G traces using Samsung Android phones. Log files can be analyzed with Tobias Engel's "xgoldmon":https://github.com/2b-as/xgoldmon tool, which heavily inspired the development of xgoldscanner. h3. Requirements: * Samsung Galaxy S2 / S3 phone * Micro-USB cable * Linux Computer h3. Download: * Source Code (bash) * Live System h3. Disclaimer The active tests include an active part. First, your phone will place outgoing calls to a dedicated number. This number will always be busy and never answer in order to rule out voice charges as best as we can. Secondly, your phone will send SMS short messages via an invalid SMS-C to an invalid number. During our tests we have not found a European network that charges for these transactions. However, we can not rule out that you may be charged in specific settings. To control for involuntary charges, we strongly advise the use of a dedicated pre-paid SIM card for these tests. h3. Instructions # Download # unpack # run: <pre>sudo ./xgoldscanner.sh -n [telephone number, e.g. +491234567]</pre> Optional parameters: * -g conduct GPRS test * -d display debug messages * -o offline mode [skip log upload for manual submission] * -3 conduct 3G tests only [skip 2G tests] * -y assume "yes" to questions and confirmation dialogues [for automated testing] * -i <n> repeat each test <n> times (default is 5) h3. Advanced usage Use Tobias Engel's "xgoldmon":https://github.com/2b-as/xgoldmon tool to analyze log files. h3.
