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

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