Revision 8 (Karsten, 12/23/2013 01:48 PM) → Revision 9/32 (Karsten, 12/23/2013 02:35 PM)

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.
