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

  89       <div class="date">24th September 2017</div>
  90       <div class="body"><p>A little more than a month ago I wrote
  91 <a href="http://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html">how
  92 to observe the SIM card ID (aka IMSI number) of mobile phones talking
  93 to nearby mobile phone base stations using Debian GNU/Linux and a
  94 cheap USB software defined radio</a>, and thus being able to pinpoint
  95 the location of people and equipment (like cars and trains) with an
  96 accuracy of a few kilometer.  Since then we have worked to make the
  97 procedure even simpler, and it is now possible to do this without any
  98 manual frequency tuning and without building your own packages.</p>
  99
 100 <p>The <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a>
 101 package is now included in Debian testing and unstable, and the
 102 IMSI-catcher code no longer require root access to fetch and decode
 103 the GSM data collected using gr-gsm.</p>
 104
 105 <p>Here is an updated recipe, using packages built by Debian and a git
 106 clone of two python scripts:</p>
 107
 108 <ol>
 109
 110 <li>Start with a Debian machine running the Buster version (aka
 111   testing).</li>
 112
 113 <li>Run '<tt>apt install gr-gsm python-numpy python-scipy
 114   python-scapy</tt>' as root to install required packages.</li>
 115
 116 <li>Fetch the code decoding GSM packages using '<tt>git clone
 117   github.com/Oros42/IMSI-catcher.git</tt>'.</li>
 118
 119 <li>Insert USB software defined radio supported by GNU Radio.</li>
 120
 121 <li>Enter the IMSI-catcher directory and run '<tt>python
 122   scan-and-livemon</tt>' to locate the frequency of nearby base
 123   stations and start listening for GSM packages on one of them.</li>
 124
 125 <li>Enter the IMSI-catcher directory and run '<tt>python
 126   simple_IMSI-catcher.py</tt>' to display the collected information.</li>
 127
 128 </ol>
 129
 130 <p>Note, due to a bug somewhere the scan-and-livemon program (actually
 131 <a href="https://github.com/ptrkrysik/gr-gsm/issues/336">its underlying
 132 program grgsm_scanner</a>) do not work with the HackRF radio.  It does
 133 work with RTL 8232 and other similar USB radio receivers you can get
 134 very cheaply
 135 (<a href="https://www.ebay.com/sch/items/?_nkw=rtl+2832">for example
 136 from ebay</a>), so for now the solution is to scan using the RTL radio
 137 and only use HackRF for fetching GSM data.</p>
 138
 139 <p>As far as I can tell, a cell phone only show up on one of the
 140 frequencies at the time, so if you are going to track and count every
 141 cell phone around you, you need to listen to all the frequencies used.
 142 To listen to several frequencies, use the --numrecv argument to
 143 scan-and-livemon to use several receivers.  Further, I am not sure if
 144 phones using 3G or 4G will show as talking GSM to base stations, so
 145 this approach might not see all phones around you.  I typically see
 146 0-400 IMSI numbers an hour when looking around where I live.</p>
 147
 148 <p>I've tried to run the scanner on a
 149 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi 2 and 3
 150 running Debian Buster</a>, but the grgsm_livemon_headless process seem
 151 to be too CPU intensive to keep up.  When GNU Radio print 'O' to
 152 stdout, I am told there it is caused by a buffer overflow between the
 153 radio and GNU Radio, caused by the program being unable to read the
 154 GSM data fast enough.  If you see a stream of 'O's from the terminal
 155 where you started scan-and-livemon, you need a give the process more
 156 CPU power.  Perhaps someone are able to optimize the code to a point
 157 where it become possible to set up RPi3 based GSM sniffers?  I tried
 158 using Raspbian instead of Debian, but there seem to be something wrong
 159 with GNU Radio on raspbian, causing glibc to abort().</p>

 174       <div class="body"><p>For noen dager siden publiserte Jon Wessel-Aas en bloggpost om
 175 «<a href="http://www.uhuru.biz/?p=1821">Konklusjonen om datalagring som
 176 EU-kommisjonen ikke ville at vi skulle få se</a>».  Det er en
 177 interessant gjennomgang av EU-domstolens syn på snurpenotovervåkning

 179 EU-lovgivingen.</p>
 180
 181 <p>Valgkampen går for fullt i Norge, og om noen få dager er siste
 182 frist for å avgi stemme.  En ting er sikkert, Høyre og Arbeiderpartiet
 183 får ikke min stemme
 184 <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
 185 gangen heller</a>.  Jeg har ikke glemt at de tvang igjennom loven som
 186 skulle pålegge alle data- og teletjenesteleverandører å overvåke alle
 187 sine kunder.  En lov som er vedtatt, og aldri opphevet igjen.</p>
 188
 189 <p>Det er tydelig fra diskusjonen rundt grenseløs digital overvåkning
 190 (eller "Digital Grenseforsvar" som det kalles i Orvellisk nytale) at
 191 hverken Høyre og Arbeiderpartiet har noen prinsipielle sperrer mot å
 192 overvåke hele befolkningen, og diskusjonen så langt tyder på at flere
 193 av de andre partiene heller ikke har det. Mange av

 195 for Datalagringsdirektivet i Stortinget</a> (64 fra Arbeiderpartiet,
 196 25 fra Høyre) er fortsatt aktive og argumenterer fortsatt for å radere
 197 vekk mer av innbyggernes privatsfære.</p>
 198
 199 <p>Når myndighetene demonstrerer sin mistillit til folket, tror jeg
 200 folket selv bør legge litt innsats i å verne sitt privatliv, ved å ta
 201 i bruk ende-til-ende-kryptert kommunikasjon med sine kjente og kjære,
 202 og begrense hvor mye privat informasjon som deles med uvedkommende.
 203 Det er jo ingenting som tyder på at myndighetene kommer til å være vår
 204 privatsfære.
 205 <a href="http://people.skolelinux.org/pere/blog/How_to_talk_with_your_loved_ones_in_private.html">Det
 206 er mange muligheter</a>.  Selv har jeg litt sans for

 228       <div class="date"> 9th August 2017</div>
 229       <div class="body"><p>On friday, I came across an interesting article in the Norwegian
 230 web based ICT news magazine digi.no on
 231 <a href="https://www.digi.no/artikler/sikkerhetsforsker-lagde-enkel-imsi-catcher-for-60-kroner-na-kan-mobiler-kartlegges-av-alle/398588">how
 232 to collect the IMSI numbers of nearby cell phones</a> using the cheap
 233 DVB-T software defined radios.  The article refered to instructions
 234 and <a href="https://www.youtube.com/watch?v=UjwgNd_as30">a recipe by
 235 Keld Norman on Youtube on how to make a simple $7 IMSI Catcher</a>, and I decided to test them out.</p>
 236
 237 <p>The instructions said to use Ubuntu, install pip using apt (to
 238 bypass apt), use pip to install pybombs (to bypass both apt and pip),
 239 and the ask pybombs to fetch and build everything you need from
 240 scratch.  I wanted to see if I could do the same on the most recent
 241 Debian packages, but this did not work because pybombs tried to build
 242 stuff that no longer build with the most recent openssl library or
 243 some other version skew problem.  While trying to get this recipe
 244 working, I learned that the apt->pip->pybombs route was a long detour,
 245 and the only piece of software dependency missing in Debian was the
 246 gr-gsm package.  I also found out that the lead upstream developer of
 247 gr-gsm (the name stand for GNU Radio GSM) project already had a set of
 248 Debian packages provided in an Ubuntu PPA repository.  All I needed to
 249 do was to dget the Debian source package and built it.</p>
 250
 251 <p>The IMSI collector is a python script listening for packages on the
 252 loopback network device and printing to the terminal some specific GSM
 253 packages with IMSI numbers in them.  The code is fairly short and easy
 254 to understand.  The reason this work is because gr-gsm include a tool
 255 to read GSM data from a software defined radio like a DVB-T USB stick
 256 and other software defined radios, decode them and inject them into a
 257 network device on your Linux machine (using the loopback device by
 258 default).  This proved to work just fine, and I've been testing the
 259 collector for a few days now.</p>
 260
 261 <p>The updated and simpler recipe is thus to</p>
 262
 263 <ol>
 264
 265 <li>start with a Debian machine running Stretch or newer,</li>
 266
 267 <li>build and install the gr-gsm package available from
 268 <a href="http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/">http://ppa.launchpad.net/ptrkrysik/gr-gsm/ubuntu/pool/main/g/gr-gsm/</a>,</li>
 269
 270 <li>clone the git repostory from <a href="https://github.com/Oros42/IMSI-catcher">https://github.com/Oros42/IMSI-catcher</a>,</li>
 271
 272 <li>run grgsm_livemon and adjust the frequency until the terminal
 273 where it was started is filled with a stream of text (meaning you
 274 found a GSM station).</li>
 275
 276 <li>go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.</li>
 277
 278 </ol>
 279
 280 <p>To make it even easier in the future to get this sniffer up and
 281 running, I decided to package
 282 <a href="https://github.com/ptrkrysik/gr-gsm/">the gr-gsm project</a>
 283 for Debian (<a href="https://bugs.debian.org/871055">WNPP
 284 #871055</a>), and the package was uploaded into the NEW queue today.
 285 Luckily the gnuradio maintainer has promised to help me, as I do not
 286 know much about gnuradio stuff yet.</p>
 287
 288 <p>I doubt this "IMSI cacher" is anywhere near as powerfull as
 289 commercial tools like
 290 <a href="https://www.thespyphone.com/portable-imsi-imei-catcher/">The
 291 Spy Phone Portable IMSI / IMEI Catcher</a> or the
 292 <a href="https://en.wikipedia.org/wiki/Stingray_phone_tracker">Harris
 293 Stingray</a>, but I hope the existance of cheap alternatives can make
 294 more people realise how their whereabouts when carrying a cell phone
 295 is easily tracked.  Seeing the data flow on the screen, realizing that
 296 I live close to a police station and knowing that the police is also
 297 wearing cell phones, I wonder how hard it would be for criminals to
 298 track the position of the police officers to discover when there are
 299 police near by, or for foreign military forces to track the location
 300 of the Norwegian military forces, or for anyone to track the location
 301 of government officials...</p>
 302
 303 <p>It is worth noting that the data reported by the IMSI-catcher
 304 script mentioned above is only a fraction of the data broadcasted on
 305 the GSM network.  It will only collect one frequency at the time,
 306 while a typical phone will be using several frequencies, and not all
 307 phones will be using the frequencies tracked by the grgsm_livemod
 308 program.  Also, there is a lot of radio chatter being ignored by the
 309 simple_IMSI-catcher script, which would be collected by extending the
 310 parser code.  I wonder if gr-gsm can be set up to listen to more than
 311 one frequency?</p>

 365 «<a href="https://freedom-to-tinker.com/2017/06/21/killing-car-privacy-by-federal-mandate/">Killing
 366 car privacy by federal mandate</a>» av Leonid Reyzin på Freedom to
 367 Tinker i dag, og det gleder meg å se en god gjennomgang om hvorfor det
 368 er et urimelig inngrep i privatsfæren å la alle biler kringkaste sin
 369 posisjon og bevegelse via radio.  Det omtalte forslaget basert på
 370 Dedicated Short Range Communication (DSRC) kalles Basic Safety Message
 371 (BSM) i USA og Cooperative Awareness Message (CAM) i Europa, og det
 372 norske Vegvesenet er en av de som ser ut til å kunne tenke seg å
 373 pålegge alle biler å fjerne nok en bit av innbyggernes privatsfære.
 374 Anbefaler alle å lese det som står der.
 375
 376 <p>Mens jeg tittet litt på DSRC på biler i Norge kom jeg over et sitat
 377 jeg synes er illustrativt for hvordan det offentlige Norge håndterer
 378 problemstillinger rundt innbyggernes privatsfære i SINTEF-rapporten
 379 «<a href="https://www.sintef.no/publikasjoner/publikasjon/Download/?pubid=SINTEF+A23933">Informasjonssikkerhet
 380 i AutoPASS-brikker</a>» av Trond Foss:</p>
 381
 382 <p><blockquote>
 383 «Rapporten ser ikke på informasjonssikkerhet knyttet til personlig
 384   integritet.»
 385 </blockquote></p>
 386
 387 <p>Så enkelt kan det tydeligvis gjøres når en vurderer
 388 informasjonssikkerheten.  Det holder vel at folkene på toppen kan si
 389 at «Personvernet er ivaretatt», som jo er den populære intetsigende
 390 frasen som gjør at mange tror enkeltindividers integritet tas vare på.
 391 Sitatet fikk meg til å undres på hvor ofte samme tilnærming, å bare se
 392 bort fra behovet for personlig itegritet, blir valgt når en velger å
 393 legge til rette for nok et inngrep i privatsfæren til personer i
 394 Norge.  Det er jo sjelden det får reaksjoner.  Historien om
 395 reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et
 396 unntak og toppen av isfjellet, desverre.  Tror jeg fortsatt takker nei
 397 til både AutoPASS og holder meg så langt unna det norske helsevesenet
 398 som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter
 399 individets privatsfære og personlige integritet høyere enn kortsiktig
 400 gevist og samfunnsnytte.</p>

 541       <div class="date"> 7th June 2017</div>
 542       <div class="body"><p><em>This is a copy of
 543 <a href="https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html">an
 544 email I posted to the nikita-noark mailing list</a>.  Please follow up
 545 there if you would like to discuss this topic.  The background is that
 546 we are making a free software archive system based on the Norwegian
 547 <a href="https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden">Noark
 548 5 standard</a> for government archives.</em></p>
 549
 550 <p>I've been wondering a bit lately how trusted timestamps could be
 551 stored in Noark 5.
 552 <a href="https://en.wikipedia.org/wiki/Trusted_timestamping">Trusted
 553 timestamps</a> can be used to verify that some information
 554 (document/file/checksum/metadata) have not been changed since a
 555 specific time in the past.  This is useful to verify the integrity of
 556 the documents in the archive.</p>
 557
 558 <p>Then it occured to me, perhaps the trusted timestamps could be
 559 stored as dokument variants (ie dokumentobjekt referered to from
 560 dokumentbeskrivelse) with the filename set to the hash it is
 561 stamping?</p>
 562
 563 <p>Given a "dokumentbeskrivelse" with an associated "dokumentobjekt",
 564 a new dokumentobjekt is associated with "dokumentbeskrivelse" with the
 565 same attributes as the stamped dokumentobjekt except these
 566 attributes:</p>
 567
 568 <ul>
 569
 570 <li>format -> "RFC3161"
 571 <li>mimeType -> "application/timestamp-reply"
 572 <li>formatDetaljer -> "&lt;source URL for timestamp service&gt;"
 573 <li>filenavn -> "&lt;sjekksum&gt;.tsr"
 574
 575 </ul>
 576
 577 <p>This assume a service following
 578 <a href="https://tools.ietf.org/html/rfc3161">IETF RFC 3161</a> is
 579 used, which specifiy the given MIME type for replies and the .tsr file
 580 ending for the content of such trusted timestamp.  As far as I can
 581 tell from the Noark 5 specifications, it is OK to have several
 582 variants/renderings of a dokument attached to a given
 583 dokumentbeskrivelse objekt.  It might be stretching it a bit to make
 584 some of these variants represent crypto-signatures useful for
 585 verifying the document integrity instead of representing the dokument
 586 itself.</p>
 587
 588 <p>Using the source of the service in formatDetaljer allow several
 589 timestamping services to be used.  This is useful to spread the risk
 590 of key compromise over several organisations.  It would only be a
 591 problem to trust the timestamps if all of the organisations are
 592 compromised.</p>
 593
 594 <p>The following oneliner on Linux can be used to generate the tsr
 595 file.  $input is the path to the file to checksum, and $sha256 is the
 596 SHA-256 checksum of the file (ie the "<sjekksum>.tsr" value mentioned
 597 above).</p>
 598
 599 <p><blockquote><pre>
 600 openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \
 601   | curl -s -H "Content-Type: application/timestamp-query" \
 602       --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr
 603 </pre></blockquote></p>
 604
 605 <p>To verify the timestamp, you first need to download the public key
 606 of the trusted timestamp service, for example using this command:</p>
 607
 608 <p><blockquote><pre>
 609 wget -O ca-cert.txt \
 610   https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
 611 </pre></blockquote></p>
 612
 613 <p>Note, the public key should be stored alongside the timestamps in
 614 the archive to make sure it is also available 100 years from now.  It
 615 is probably a good idea to standardise how and were to store such
 616 public keys, to make it easier to find for those trying to verify
 617 documents 100 or 1000 years from now. :)</p>
 618
 619 <p>The verification itself is a simple openssl command:</p>
 620
 621 <p><blockquote><pre>
 622 openssl ts -verify -data $inputfile -in $sha256.tsr \
 623   -CAfile ca-cert.txt -text
 624 </pre></blockquote></p>
 625
 626 <p>Is there any reason this approach would not work?  Is it somehow against
 627 the Noark 5 specification?</p>

 646 på om den fri oversetterløsningen
 647 <a href="https://www.apertium.org/">Apertium</a> ville gjort en bedre
 648 jobb enn Utdanningsdirektoratet.  Det kan se slik ut.</p>
 649

 651
 652 <blockquote>
 653 <p>Drøft utfordringene knyttet til nasjonalstatenes og andre aktørers
 654 rolle og muligheter til å håndtere internasjonale utfordringer, som
 655 for eksempel flykningekrisen.</p>

 658 på temaet:</p>

 665
 666 <p>Dette oversetter Apertium slik:</p>
 667
 668 <blockquote>
 669 <p>Drøft utfordringane knytte til nasjonalstatane sine og rolla til
 670 andre aktørar og høve til å handtera internasjonale utfordringar, som

 682
 683 <p>Ord som ikke ble forstått er markert med stjerne (*), og trenger
 684 ekstra språksjekk.  Men ingen ord er forsvunnet, slik det var i
 685 oppgaven elevene fikk presentert på eksamen.  Jeg mistenker dog at
 686 "andre aktørers rolle og muligheter til ..." burde vært oversatt til
 687 "rolla til andre aktørar og deira høve til ..." eller noe slikt, men
 688 det er kanskje flisespikking.  Det understreker vel bare at det alltid
 689 trengs korrekturlesning etter automatisk oversettelse.</p>
