  32         <p>Every mobile phone announce its existence over radio to the nearby
  33 mobile cell towers.  And this radio chatter is available for anyone
  34 with a radio receiver capable of receiving them.  Details about the
  35 mobile phones with very good accuracy is of course collected by the
  36 phone companies, but this is not the topic of this blog post.  The
  37 mobile phone radio chatter make it possible to figure out when a cell
  38 phone is nearby, as it include the SIM card ID (IMSI).  By paying
  39 attention over time, one can see when a phone arrive and when it leave
  40 an area.  I believe it would be nice to make this information more
  41 available to the general public, to make more people aware of how
  42 their phones are announcing their whereabouts to anyone that care to
  43 listen.</p>
  44
  45 <p>I am very happy to report that we managed to get something
  46 visualizing this information up and running for
  47 <a href="http://norwaymakers.org/osf17">Oslo Skaperfestival 2017</a>
  48 (Oslo Makers Festival) taking place today and tomorrow at Deichmanske
  49 library.  The solution is based on the
  50 <a href="http://people.skolelinux.org/pere/blog/Easier_recipe_to_observe_the_cell_phones_around_you.html">simple
  51 recipe for listening to GSM chatter</a> I posted a few days ago, and
  52 will show up at the stand of <a href="http://sonen.ifi.uio.no/">Åpen
  53 Sone from the Computer Science department of the University of
  54 Oslo</a>.  The presentation will show the nearby mobile phones (aka
  55 IMSIs) as dots in a web browser graph, with lines to the dot
  56 representing mobile base station it is talking to. It was working in
  57 the lab yesterday, and was moved into place this morning.</p>
  58
  59 <p>We set up a fairly powerful desktop machine using Debian
  60 Buster/Testing with several (five, I believe) RTL2838 DVB-T receivers
  61 connected and visualize the visible cell phone towers using an
  62 <a href="https://github.com/marlow925/hopglass">English version of
  63 Hopglass</a>.  A fairly powerfull machine is needed as the
  64 grgsm_livemon_headless processes from
  65 <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a> converting
  66 the radio signal to data packages is quite CPU intensive.</p>
  67
  68 <p>The frequencies to listen to, are identified using a slightly
  69 patched scan-and-livemon (to set the --args values for each receiver),
  70 and the Hopglass data is generated using the
  71 <a href="https://github.com/petterreinholdtsen/IMSI-catcher/tree/meshviewer-output">patches
  72 in my meshviewer-output branch</a>.  For some reason we could not get
  73 more than four SDRs working.  There is also a geographical map trying
  74 to show the location of the base stations, but I believe their
  75 coordinates are hardcoded to some random location in Germany, I
  76 believe.  The code should be replaced with code to look up location in
  77 a text file, a sqlite database or one of the online databases
  78 mentioned in
  79 <a href="https://github.com/Oros42/IMSI-catcher/issues/14">the github
  80 issue for the topic</a>.
  81
  82 <p>If this sound interesting, visit the stand at the festival!</p>

 103         <p>A little more than a month ago I wrote
 104 <a href="http://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html">how
 105 to observe the SIM card ID (aka IMSI number) of mobile phones talking
 106 to nearby mobile phone base stations using Debian GNU/Linux and a
 107 cheap USB software defined radio</a>, and thus being able to pinpoint
 108 the location of people and equipment (like cars and trains) with an
 109 accuracy of a few kilometer.  Since then we have worked to make the
 110 procedure even simpler, and it is now possible to do this without any
 111 manual frequency tuning and without building your own packages.</p>
 112
 113 <p>The <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a>
 114 package is now included in Debian testing and unstable, and the
 115 IMSI-catcher code no longer require root access to fetch and decode
 116 the GSM data collected using gr-gsm.</p>
 117
 118 <p>Here is an updated recipe, using packages built by Debian and a git
 119 clone of two python scripts:</p>
 120
 121 <ol>
 122
 123 <li>Start with a Debian machine running the Buster version (aka
 124   testing).</li>
 125
 126 <li>Run '<tt>apt install gr-gsm python-numpy python-scipy
 127   python-scapy</tt>' as root to install required packages.</li>
 128
 129 <li>Fetch the code decoding GSM packages using '<tt>git clone
 130   github.com/Oros42/IMSI-catcher.git</tt>'.</li>
 131
 132 <li>Insert USB software defined radio supported by GNU Radio.</li>
 133
 134 <li>Enter the IMSI-catcher directory and run '<tt>python
 135   scan-and-livemon</tt>' to locate the frequency of nearby base
 136   stations and start listening for GSM packages on one of them.</li>
 137
 138 <li>Enter the IMSI-catcher directory and run '<tt>python
 139   simple_IMSI-catcher.py</tt>' to display the collected information.</li>
 140
 141 </ol>
 142
 143 <p>Note, due to a bug somewhere the scan-and-livemon program (actually
 144 <a href="https://github.com/ptrkrysik/gr-gsm/issues/336">its underlying
 145 program grgsm_scanner</a>) do not work with the HackRF radio.  It does
 146 work with RTL 8232 and other similar USB radio receivers you can get
 147 very cheaply
 148 (<a href="https://www.ebay.com/sch/items/?_nkw=rtl+2832">for example
 149 from ebay</a>), so for now the solution is to scan using the RTL radio
 150 and only use HackRF for fetching GSM data.</p>
 151
 152 <p>As far as I can tell, a cell phone only show up on one of the
 153 frequencies at the time, so if you are going to track and count every
 154 cell phone around you, you need to listen to all the frequencies used.
 155 To listen to several frequencies, use the --numrecv argument to
 156 scan-and-livemon to use several receivers.  Further, I am not sure if
 157 phones using 3G or 4G will show as talking GSM to base stations, so
 158 this approach might not see all phones around you.  I typically see
 159 0-400 IMSI numbers an hour when looking around where I live.</p>
 160
 161 <p>I've tried to run the scanner on a
 162 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi 2 and 3
 163 running Debian Buster</a>, but the grgsm_livemon_headless process seem
 164 to be too CPU intensive to keep up.  When GNU Radio print 'O' to
 165 stdout, I am told there it is caused by a buffer overflow between the
 166 radio and GNU Radio, caused by the program being unable to read the
 167 GSM data fast enough.  If you see a stream of 'O's from the terminal
 168 where you started scan-and-livemon, you need a give the process more
 169 CPU power.  Perhaps someone are able to optimize the code to a point
 170 where it become possible to set up RPi3 based GSM sniffers?  I tried
 171 using Raspbian instead of Debian, but there seem to be something wrong
 172 with GNU Radio on raspbian, causing glibc to abort().</p>

 193         <p>For noen dager siden publiserte Jon Wessel-Aas en bloggpost om
 194 «<a href="http://www.uhuru.biz/?p=1821">Konklusjonen om datalagring som
 195 EU-kommisjonen ikke ville at vi skulle få se</a>».  Det er en
 196 interessant gjennomgang av EU-domstolens syn på snurpenotovervåkning
 197 av befolkningen, som er klar på at det er i strid med
 198 EU-lovgivingen.</p>
 199
 200 <p>Valgkampen går for fullt i Norge, og om noen få dager er siste
 201 frist for å avgi stemme.  En ting er sikkert, Høyre og Arbeiderpartiet
 202 får ikke min stemme
 203 <a href="http://people.skolelinux.org/pere/blog/Datalagringsdirektivet_gj_r_at_Oslo_H_yre_og_Arbeiderparti_ikke_f_r_min_stemme_i__r.html">denne
 204 gangen heller</a>.  Jeg har ikke glemt at de tvang igjennom loven som
 205 skulle pålegge alle data- og teletjenesteleverandører å overvåke alle
 206 sine kunder.  En lov som er vedtatt, og aldri opphevet igjen.</p>
 207
 208 <p>Det er tydelig fra diskusjonen rundt grenseløs digital overvåkning
 209 (eller "Digital Grenseforsvar" som det kalles i Orvellisk nytale) at
 210 hverken Høyre og Arbeiderpartiet har noen prinsipielle sperrer mot å
 211 overvåke hele befolkningen, og diskusjonen så langt tyder på at flere
 212 av de andre partiene heller ikke har det. Mange av
 213 <a href="https://data.holderdeord.no/votes/1301946411e">de som stemte
 214 for Datalagringsdirektivet i Stortinget</a> (64 fra Arbeiderpartiet,
 215 25 fra Høyre) er fortsatt aktive og argumenterer fortsatt for å radere
 216 vekk mer av innbyggernes privatsfære.</p>
 217
 218 <p>Når myndighetene demonstrerer sin mistillit til folket, tror jeg
 219 folket selv bør legge litt innsats i å verne sitt privatliv, ved å ta
 220 i bruk ende-til-ende-kryptert kommunikasjon med sine kjente og kjære,
 221 og begrense hvor mye privat informasjon som deles med uvedkommende.
 222 Det er jo ingenting som tyder på at myndighetene kommer til å være vår
 223 privatsfære.
 224 <a href="http://people.skolelinux.org/pere/blog/How_to_talk_with_your_loved_ones_in_private.html">Det
 225 er mange muligheter</a>.  Selv har jeg litt sans for
 226 <a href="https://ring.cx/">Ring</a>, som er basert på p2p-teknologi
 227 uten sentral kontroll, er fri programvare, og støtter meldinger, tale
 228 og video.  Systemet er tilgjengelig ut av boksen fra
 229 <a href="https://tracker.debian.org/pkg/ring">Debian</a> og
 230 <a href="https://launchpad.net/ubuntu/+source/ring">Ubuntu</a>, og det
 231 finnes pakker for Android, MacOSX og Windows.  Foreløpig er det få
 232 brukere med Ring, slik at jeg også bruker
 233 <a href="https://signal.org/">Signal</a> som nettleserutvidelse.</p>
