  25       <div class="body">Når jeg holder på med ulike prosjekter, så trenger jeg stadig ulike
  26 skruer.  Det siste prosjektet jeg holder på med er å lage
  27 <a href="https://www.thingiverse.com/thing:676916">en boks til en
  28 HDMI-touch-skjerm</a> som skal brukes med Raspberry Pi.  Boksen settes
  29 sammen emed skruer og bolter, og jeg har vært i tvil om hvor jeg kan
  30 få tak i de riktige skruene.  Clas Ohlson eller Jernia i nærheten har
  31 sjelden hatt det jeg trenger.  Men her om dagen fikk jeg et fantastisk
  32 tips for oss som bor i Oslo.
  33 <a href="http://www.zachskruer.no/">Zachariassen Jernvare AS</a> i
  34 <a href="http://www.openstreetmap.org/?mlat=59.93421&mlon=10.76795#map=19/59.93421/10.76795">Hegermannsgate
  35 23A på Torshov</a> har et fantastisk utvalg, og åpent mellom 09:00 og
  36 17:00.  De selger skruer, muttere, bolter, skiver etc i løs vekt, og
  37 så langt har jeg fått alt jeg har lett etter.  De har i tillegg det
  38 meste av annen jernvare, som verktøy, lamper, ledninger, etc.  Jeg
  39 håper de har nok kunder til å holde det gående lenge, da dette er en
  40 butikk jeg kommer til å besøke ofte.  Butikken er et funn å ha i
  41 nabolaget for oss som liker å bygge litt selv. :)</p>

  56       <div class="body"><p>Every mobile phone announce its existence over radio to the nearby
  57 mobile cell towers.  And this radio chatter is available for anyone
  58 with a radio receiver capable of receiving them.  Details about the
  59 mobile phones with very good accuracy is of course collected by the
  60 phone companies, but this is not the topic of this blog post.  The
  61 mobile phone radio chatter make it possible to figure out when a cell
  62 phone is nearby, as it include the SIM card ID (IMSI).  By paying
  63 attention over time, one can see when a phone arrive and when it leave
  64 an area.  I believe it would be nice to make this information more
  65 available to the general public, to make more people aware of how
  66 their phones are announcing their whereabouts to anyone that care to
  67 listen.</p>
  68
  69 <p>I am very happy to report that we managed to get something
  70 visualizing this information up and running for
  71 <a href="http://norwaymakers.org/osf17">Oslo Skaperfestival 2017</a>
  72 (Oslo Makers Festival) taking place today and tomorrow at Deichmanske
  73 library.  The solution is based on the
  74 <a href="http://people.skolelinux.org/pere/blog/Easier_recipe_to_observe_the_cell_phones_around_you.html">simple
  75 recipe for listening to GSM chatter</a> I posted a few days ago, and
  76 will show up at the stand of <a href="http://sonen.ifi.uio.no/">Åpen
  77 Sone from the Computer Science department of the University of
  78 Oslo</a>.  The presentation will show the nearby mobile phones (aka
  79 IMSIs) as dots in a web browser graph, with lines to the dot
  80 representing mobile base station it is talking to. It was working in
  81 the lab yesterday, and was moved into place this morning.</p>
  82
  83 <p>We set up a fairly powerful desktop machine using Debian
  84 Buster/Testing with several (five, I believe) RTL2838 DVB-T receivers
  85 connected and visualize the visible cell phone towers using an
  86 <a href="https://github.com/marlow925/hopglass">English version of
  87 Hopglass</a>.  A fairly powerfull machine is needed as the
  88 grgsm_livemon_headless processes from
  89 <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a> converting
  90 the radio signal to data packages is quite CPU intensive.</p>
  91
  92 <p>The frequencies to listen to, are identified using a slightly
  93 patched scan-and-livemon (to set the --args values for each receiver),
  94 and the Hopglass data is generated using the
  95 <a href="https://github.com/petterreinholdtsen/IMSI-catcher/tree/meshviewer-output">patches
  96 in my meshviewer-output branch</a>.  For some reason we could not get
  97 more than four SDRs working.  There is also a geographical map trying
  98 to show the location of the base stations, but I believe their
  99 coordinates are hardcoded to some random location in Germany, I
 100 believe.  The code should be replaced with code to look up location in
 101 a text file, a sqlite database or one of the online databases
 102 mentioned in
 103 <a href="https://github.com/Oros42/IMSI-catcher/issues/14">the github
 104 issue for the topic</a>.

 106 <p>If this sound interesting, visit the stand at the festival!</p>

 120       <div class="date">24th September 2017</div>
 121       <div class="body"><p>A little more than a month ago I wrote
 122 <a href="http://people.skolelinux.org/pere/blog/Simpler_recipe_on_how_to_make_a_simple__7_IMSI_Catcher_using_Debian.html">how
 123 to observe the SIM card ID (aka IMSI number) of mobile phones talking
 124 to nearby mobile phone base stations using Debian GNU/Linux and a
 125 cheap USB software defined radio</a>, and thus being able to pinpoint
 126 the location of people and equipment (like cars and trains) with an
 127 accuracy of a few kilometer.  Since then we have worked to make the
 128 procedure even simpler, and it is now possible to do this without any
 129 manual frequency tuning and without building your own packages.</p>
 130
 131 <p>The <a href="https://tracker.debian.org/pkg/gr-gsm">gr-gsm</a>
 132 package is now included in Debian testing and unstable, and the
 133 IMSI-catcher code no longer require root access to fetch and decode
 134 the GSM data collected using gr-gsm.</p>
 135
 136 <p>Here is an updated recipe, using packages built by Debian and a git
 137 clone of two python scripts:</p>
 138
 139 <ol>
 140
 141 <li>Start with a Debian machine running the Buster version (aka
 142   testing).</li>
 143
 144 <li>Run '<tt>apt install gr-gsm python-numpy python-scipy
 145   python-scapy</tt>' as root to install required packages.</li>
 146
 147 <li>Fetch the code decoding GSM packages using '<tt>git clone
 148   github.com/Oros42/IMSI-catcher.git</tt>'.</li>
 149
 150 <li>Insert USB software defined radio supported by GNU Radio.</li>
 151
 152 <li>Enter the IMSI-catcher directory and run '<tt>python
 153   scan-and-livemon</tt>' to locate the frequency of nearby base
 154   stations and start listening for GSM packages on one of them.</li>
 155
 156 <li>Enter the IMSI-catcher directory and run '<tt>python
 157   simple_IMSI-catcher.py</tt>' to display the collected information.</li>
 158
 159 </ol>
 160
 161 <p>Note, due to a bug somewhere the scan-and-livemon program (actually
 162 <a href="https://github.com/ptrkrysik/gr-gsm/issues/336">its underlying
 163 program grgsm_scanner</a>) do not work with the HackRF radio.  It does
 164 work with RTL 8232 and other similar USB radio receivers you can get
 165 very cheaply
 166 (<a href="https://www.ebay.com/sch/items/?_nkw=rtl+2832">for example
 167 from ebay</a>), so for now the solution is to scan using the RTL radio
 168 and only use HackRF for fetching GSM data.</p>
 169
 170 <p>As far as I can tell, a cell phone only show up on one of the
 171 frequencies at the time, so if you are going to track and count every
 172 cell phone around you, you need to listen to all the frequencies used.
 173 To listen to several frequencies, use the --numrecv argument to
 174 scan-and-livemon to use several receivers.  Further, I am not sure if
 175 phones using 3G or 4G will show as talking GSM to base stations, so
 176 this approach might not see all phones around you.  I typically see
 177 0-400 IMSI numbers an hour when looking around where I live.</p>
 178
 179 <p>I've tried to run the scanner on a
 180 <a href="https://wiki.debian.org/RaspberryPi">Raspberry Pi 2 and 3
 181 running Debian Buster</a>, but the grgsm_livemon_headless process seem
 182 to be too CPU intensive to keep up.  When GNU Radio print 'O' to
 183 stdout, I am told there it is caused by a buffer overflow between the
 184 radio and GNU Radio, caused by the program being unable to read the
 185 GSM data fast enough.  If you see a stream of 'O's from the terminal
 186 where you started scan-and-livemon, you need a give the process more
 187 CPU power.  Perhaps someone are able to optimize the code to a point
 188 where it become possible to set up RPi3 based GSM sniffers?  I tried
 189 using Raspbian instead of Debian, but there seem to be something wrong
 190 with GNU Radio on raspbian, causing glibc to abort().</p>

 204       <div class="date"> 7th September 2017</div>
 205       <div class="body"><p>For noen dager siden publiserte Jon Wessel-Aas en bloggpost om
 206 «<a href="http://www.uhuru.biz/?p=1821">Konklusjonen om datalagring som
 207 EU-kommisjonen ikke ville at vi skulle få se</a>».  Det er en
 208 interessant gjennomgang av EU-domstolens syn på snurpenotovervåkning
 209 av befolkningen, som er klar på at det er i strid med
 210 EU-lovgivingen.</p>
 211
 212 <p>Valgkampen går for fullt i Norge, og om noen få dager er siste
 213 frist for å avgi stemme.  En ting er sikkert, Høyre og Arbeiderpartiet
 214 får ikke min stemme
 215 <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
 216 gangen heller</a>.  Jeg har ikke glemt at de tvang igjennom loven som
 217 skulle pålegge alle data- og teletjenesteleverandører å overvåke alle
 218 sine kunder.  En lov som er vedtatt, og aldri opphevet igjen.</p>
 219
 220 <p>Det er tydelig fra diskusjonen rundt grenseløs digital overvåkning
 221 (eller "Digital Grenseforsvar" som det kalles i Orvellisk nytale) at
 222 hverken Høyre og Arbeiderpartiet har noen prinsipielle sperrer mot å
 223 overvåke hele befolkningen, og diskusjonen så langt tyder på at flere
 224 av de andre partiene heller ikke har det. Mange av
 225 <a href="https://data.holderdeord.no/votes/1301946411e">de som stemte
 226 for Datalagringsdirektivet i Stortinget</a> (64 fra Arbeiderpartiet,
 227 25 fra Høyre) er fortsatt aktive og argumenterer fortsatt for å radere
 228 vekk mer av innbyggernes privatsfære.</p>
 229
 230 <p>Når myndighetene demonstrerer sin mistillit til folket, tror jeg
 231 folket selv bør legge litt innsats i å verne sitt privatliv, ved å ta
 232 i bruk ende-til-ende-kryptert kommunikasjon med sine kjente og kjære,
 233 og begrense hvor mye privat informasjon som deles med uvedkommende.
 234 Det er jo ingenting som tyder på at myndighetene kommer til å være vår
 235 privatsfære.
 236 <a href="http://people.skolelinux.org/pere/blog/How_to_talk_with_your_loved_ones_in_private.html">Det
 237 er mange muligheter</a>.  Selv har jeg litt sans for
 238 <a href="https://ring.cx/">Ring</a>, som er basert på p2p-teknologi

 242 <a href="https://launchpad.net/ubuntu/+source/ring">Ubuntu</a>, og det

 259       <div class="date"> 9th August 2017</div>
 260       <div class="body"><p>On friday, I came across an interesting article in the Norwegian
 261 web based ICT news magazine digi.no on
 262 <a href="https://www.digi.no/artikler/sikkerhetsforsker-lagde-enkel-imsi-catcher-for-60-kroner-na-kan-mobiler-kartlegges-av-alle/398588">how
 263 to collect the IMSI numbers of nearby cell phones</a> using the cheap
 264 DVB-T software defined radios.  The article refered to instructions
 265 and <a href="https://www.youtube.com/watch?v=UjwgNd_as30">a recipe by
 266 Keld Norman on Youtube on how to make a simple $7 IMSI Catcher</a>, and I decided to test them out.</p>
 267
 268 <p>The instructions said to use Ubuntu, install pip using apt (to
 269 bypass apt), use pip to install pybombs (to bypass both apt and pip),
 270 and the ask pybombs to fetch and build everything you need from
 271 scratch.  I wanted to see if I could do the same on the most recent
 272 Debian packages, but this did not work because pybombs tried to build
 273 stuff that no longer build with the most recent openssl library or
 274 some other version skew problem.  While trying to get this recipe
 275 working, I learned that the apt->pip->pybombs route was a long detour,
 276 and the only piece of software dependency missing in Debian was the
 277 gr-gsm package.  I also found out that the lead upstream developer of
 278 gr-gsm (the name stand for GNU Radio GSM) project already had a set of
 279 Debian packages provided in an Ubuntu PPA repository.  All I needed to
 280 do was to dget the Debian source package and built it.</p>
 281
 282 <p>The IMSI collector is a python script listening for packages on the
 283 loopback network device and printing to the terminal some specific GSM
 284 packages with IMSI numbers in them.  The code is fairly short and easy
 285 to understand.  The reason this work is because gr-gsm include a tool
 286 to read GSM data from a software defined radio like a DVB-T USB stick
 287 and other software defined radios, decode them and inject them into a
 288 network device on your Linux machine (using the loopback device by
 289 default).  This proved to work just fine, and I've been testing the
 290 collector for a few days now.</p>
 291
 292 <p>The updated and simpler recipe is thus to</p>
 293
 294 <ol>
 295
 296 <li>start with a Debian machine running Stretch or newer,</li>
 297
 298 <li>build and install the gr-gsm package available from
 299 <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>
 300
 301 <li>clone the git repostory from <a href="https://github.com/Oros42/IMSI-catcher">https://github.com/Oros42/IMSI-catcher</a>,</li>
 302
 303 <li>run grgsm_livemon and adjust the frequency until the terminal
 304 where it was started is filled with a stream of text (meaning you
 305 found a GSM station).</li>
 306
 307 <li>go into the IMSI-catcher directory and run 'sudo python simple_IMSI-catcher.py' to extract the IMSI numbers.</li>
 308
 309 </ol>
 310
 311 <p>To make it even easier in the future to get this sniffer up and
 312 running, I decided to package
 313 <a href="https://github.com/ptrkrysik/gr-gsm/">the gr-gsm project</a>
 314 for Debian (<a href="https://bugs.debian.org/871055">WNPP
 315 #871055</a>), and the package was uploaded into the NEW queue today.
 316 Luckily the gnuradio maintainer has promised to help me, as I do not
 317 know much about gnuradio stuff yet.</p>
 318
 319 <p>I doubt this "IMSI cacher" is anywhere near as powerfull as
 320 commercial tools like
 321 <a href="https://www.thespyphone.com/portable-imsi-imei-catcher/">The
 322 Spy Phone Portable IMSI / IMEI Catcher</a> or the
 323 <a href="https://en.wikipedia.org/wiki/Stingray_phone_tracker">Harris
 324 Stingray</a>, but I hope the existance of cheap alternatives can make
 325 more people realise how their whereabouts when carrying a cell phone
 326 is easily tracked.  Seeing the data flow on the screen, realizing that
 327 I live close to a police station and knowing that the police is also
 328 wearing cell phones, I wonder how hard it would be for criminals to
 329 track the position of the police officers to discover when there are
 330 police near by, or for foreign military forces to track the location
 331 of the Norwegian military forces, or for anyone to track the location
 332 of government officials...</p>
 333
 334 <p>It is worth noting that the data reported by the IMSI-catcher
 335 script mentioned above is only a fraction of the data broadcasted on
 336 the GSM network.  It will only collect one frequency at the time,
 337 while a typical phone will be using several frequencies, and not all
 338 phones will be using the frequencies tracked by the grgsm_livemod
 339 program.  Also, there is a lot of radio chatter being ignored by the
 340 simple_IMSI-catcher script, which would be collected by extending the
 341 parser code.  I wonder if gr-gsm can be set up to listen to more than
 342 one frequency?</p>

 394       <div class="date">27th June 2017</div>
 395       <div class="body"><p>Jeg kom over teksten
 396 «<a href="https://freedom-to-tinker.com/2017/06/21/killing-car-privacy-by-federal-mandate/">Killing
 397 car privacy by federal mandate</a>» av Leonid Reyzin på Freedom to
 398 Tinker i dag, og det gleder meg å se en god gjennomgang om hvorfor det
 399 er et urimelig inngrep i privatsfæren å la alle biler kringkaste sin
 400 posisjon og bevegelse via radio.  Det omtalte forslaget basert på
 401 Dedicated Short Range Communication (DSRC) kalles Basic Safety Message
 402 (BSM) i USA og Cooperative Awareness Message (CAM) i Europa, og det
 403 norske Vegvesenet er en av de som ser ut til å kunne tenke seg å
 404 pålegge alle biler å fjerne nok en bit av innbyggernes privatsfære.
 405 Anbefaler alle å lese det som står der.
 406
 407 <p>Mens jeg tittet litt på DSRC på biler i Norge kom jeg over et sitat
 408 jeg synes er illustrativt for hvordan det offentlige Norge håndterer
 409 problemstillinger rundt innbyggernes privatsfære i SINTEF-rapporten
 410 «<a href="https://www.sintef.no/publikasjoner/publikasjon/Download/?pubid=SINTEF+A23933">Informasjonssikkerhet
 411 i AutoPASS-brikker</a>» av Trond Foss:</p>
 412
 413 <p><blockquote>
 414 «Rapporten ser ikke på informasjonssikkerhet knyttet til personlig
 415   integritet.»
 416 </blockquote></p>
 417
 418 <p>Så enkelt kan det tydeligvis gjøres når en vurderer
 419 informasjonssikkerheten.  Det holder vel at folkene på toppen kan si
 420 at «Personvernet er ivaretatt», som jo er den populære intetsigende
 421 frasen som gjør at mange tror enkeltindividers integritet tas vare på.
 422 Sitatet fikk meg til å undres på hvor ofte samme tilnærming, å bare se
 423 bort fra behovet for personlig itegritet, blir valgt når en velger å
 424 legge til rette for nok et inngrep i privatsfæren til personer i
 425 Norge.  Det er jo sjelden det får reaksjoner.  Historien om
 426 reaksjonene på Helse Sør-Østs tjenesteutsetting er jo sørgelig nok et
 427 unntak og toppen av isfjellet, desverre.  Tror jeg fortsatt takker nei
 428 til både AutoPASS og holder meg så langt unna det norske helsevesenet
 429 som jeg kan, inntil de har demonstrert og dokumentert at de verdsetter
 430 individets privatsfære og personlige integritet høyere enn kortsiktig
 431 gevist og samfunnsnytte.</p>

 572       <div class="date"> 7th June 2017</div>
 573       <div class="body"><p><em>This is a copy of
 574 <a href="https://lists.nuug.no/pipermail/nikita-noark/2017-June/000297.html">an
 575 email I posted to the nikita-noark mailing list</a>.  Please follow up
 576 there if you would like to discuss this topic.  The background is that
 577 we are making a free software archive system based on the Norwegian
 578 <a href="https://www.arkivverket.no/forvaltning-og-utvikling/regelverk-og-standarder/noark-standarden">Noark
 579 5 standard</a> for government archives.</em></p>
 580
 581 <p>I've been wondering a bit lately how trusted timestamps could be
 582 stored in Noark 5.
 583 <a href="https://en.wikipedia.org/wiki/Trusted_timestamping">Trusted
 584 timestamps</a> can be used to verify that some information
 585 (document/file/checksum/metadata) have not been changed since a
 586 specific time in the past.  This is useful to verify the integrity of
 587 the documents in the archive.</p>
 588
 589 <p>Then it occured to me, perhaps the trusted timestamps could be
 590 stored as dokument variants (ie dokumentobjekt referered to from
 591 dokumentbeskrivelse) with the filename set to the hash it is
 592 stamping?</p>
 593
 594 <p>Given a "dokumentbeskrivelse" with an associated "dokumentobjekt",
 595 a new dokumentobjekt is associated with "dokumentbeskrivelse" with the
 596 same attributes as the stamped dokumentobjekt except these
 597 attributes:</p>
 598
 599 <ul>
 600
 601 <li>format -> "RFC3161"
 602 <li>mimeType -> "application/timestamp-reply"
 603 <li>formatDetaljer -> "&lt;source URL for timestamp service&gt;"
 604 <li>filenavn -> "&lt;sjekksum&gt;.tsr"
 605
 606 </ul>
 607
 608 <p>This assume a service following
 609 <a href="https://tools.ietf.org/html/rfc3161">IETF RFC 3161</a> is
 610 used, which specifiy the given MIME type for replies and the .tsr file
 611 ending for the content of such trusted timestamp.  As far as I can
 612 tell from the Noark 5 specifications, it is OK to have several
 613 variants/renderings of a dokument attached to a given
 614 dokumentbeskrivelse objekt.  It might be stretching it a bit to make
 615 some of these variants represent crypto-signatures useful for
 616 verifying the document integrity instead of representing the dokument
 617 itself.</p>
 618
 619 <p>Using the source of the service in formatDetaljer allow several
 620 timestamping services to be used.  This is useful to spread the risk
 621 of key compromise over several organisations.  It would only be a
 622 problem to trust the timestamps if all of the organisations are
 623 compromised.</p>
 624
 625 <p>The following oneliner on Linux can be used to generate the tsr
 626 file.  $input is the path to the file to checksum, and $sha256 is the
 627 SHA-256 checksum of the file (ie the "<sjekksum>.tsr" value mentioned
 628 above).</p>
 629
 630 <p><blockquote><pre>
 631 openssl ts -query -data "$inputfile" -cert -sha256 -no_nonce \
 632   | curl -s -H "Content-Type: application/timestamp-query" \
 633       --data-binary "@-" http://zeitstempel.dfn.de > $sha256.tsr
 634 </pre></blockquote></p>
 635
 636 <p>To verify the timestamp, you first need to download the public key
 637 of the trusted timestamp service, for example using this command:</p>
 638
 639 <p><blockquote><pre>
 640 wget -O ca-cert.txt \
 641   https://pki.pca.dfn.de/global-services-ca/pub/cacert/chain.txt
 642 </pre></blockquote></p>
 643
 644 <p>Note, the public key should be stored alongside the timestamps in
 645 the archive to make sure it is also available 100 years from now.  It
 646 is probably a good idea to standardise how and were to store such
 647 public keys, to make it easier to find for those trying to verify
 648 documents 100 or 1000 years from now. :)</p>
 649
 650 <p>The verification itself is a simple openssl command:</p>
 651
 652 <p><blockquote><pre>
 653 openssl ts -verify -data $inputfile -in $sha256.tsr \
 654   -CAfile ca-cert.txt -text
 655 </pre></blockquote></p>
 656
 657 <p>Is there any reason this approach would not work?  Is it somehow against
 658 the Noark 5 specification?</p>
