  25       <div class="body"><p>A little more than a month ago I wrote
  26 <a href="https://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html">how
  27 to observe the SIM card ID (aka IMSI number) of mobile phones talking
  28 to nearby mobile phone base stations using Debian GNU/Linux and a
  29 cheap USB software defined radio</a>, and thus being able to pinpoint
  30 the location of people and equipment (like cars and trains) with an
  31 accuracy of a few kilometer.  Since then we have worked to make the
  32 procedure even simpler, and it is now possible to do this without any
  33 manual frequency tuning and without building your own packages.</p>
  34
  35 <p>The <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a>
  36 package is now included in Debian testing and unstable, and the
  37 IMSI-catcher code no longer require root access to fetch and decode
  38 the GSM data collected using gr-gsm.</p>
  39
  40 <p>Here is an updated recipe, using packages built by Debian and a git
  41 clone of two python scripts:</p>
  42
  43 <ol>
  44
  45 <li>Start with a Debian machine running the Buster version (aka
  46   testing).</li>
  47
  48 <li>Run '<tt>apt install gr-gsm python-numpy python-scipy
  49   python-scapy</tt>' as root to install required packages.</li>
  50
  51 <li>Fetch the code decoding GSM packages using '<tt>git clone
  52   github.com/Oros42/IMSI-catcher.git</tt>'.</li>
  53
  54 <li>Insert USB software defined radio supported by GNU Radio.</li>
  55
  56 <li>Enter the IMSI-catcher directory and run '<tt>python
  57   scan-and-livemon</tt>' to locate the frequency of nearby base
  58   stations and start listening for GSM packages on one of them.</li>
  59
  60 <li>Enter the IMSI-catcher directory and run '<tt>python
  61   simple_IMSI-catcher.py</tt>' to display the collected information.</li>
  62
  63 </ol>
  64
  65 <p>Note, due to a bug somewhere the scan-and-livemon program (actually
  66 <a href="https://github.com/ptrkrysik/gr-gsm/issues/336">its underlying
  67 program grgsm_scanner</a>) do not work with the HackRF radio.  It does
  68 work with RTL 8232 and other similar USB radio receivers you can get
  69 very cheaply
  70 (<a href="https://www.ebay.com/sch/items/?_nkw=rtl+2832">for example
  71 from ebay</a>), so for now the solution is to scan using the RTL radio
  72 and only use HackRF for fetching GSM data.</p>
  73
  74 <p>As far as I can tell, a cell phone only show up on one of the
  75 frequencies at the time, so if you are going to track and count every
  76 cell phone around you, you need to listen to all the frequencies used.
  77 To listen to several frequencies, use the --numrecv argument to
  78 scan-and-livemon to use several receivers.  Further, I am not sure if
  79 phones using 3G or 4G will show as talking GSM to base stations, so
  80 this approach might not see all phones around you.  I typically see
  81 0-400 IMSI numbers an hour when looking around where I live.</p>
  82
  83 <p>I've tried to run the scanner on a
  84 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi 2 and 3
  85 running Debian Buster</a>, but the grgsm_livemon_headless process seem
  86 to be too CPU intensive to keep up.  When GNU Radio print 'O' to
  87 stdout, I am told there it is caused by a buffer overflow between the
  88 radio and GNU Radio, caused by the program being unable to read the
  89 GSM data fast enough.  If you see a stream of 'O's from the terminal
  90 where you started scan-and-livemon, you need a give the process more
  91 CPU power.  Perhaps someone are able to optimize the code to a point
  92 where it become possible to set up RPi3 based GSM sniffers?  I tried
  93 using Raspbian instead of Debian, but there seem to be something wrong
  94 with GNU Radio on raspbian, causing glibc to abort().</p>
