The weather was mostly nice and the atmosphere, especially at night, was really fantastic. Everybody was really nice and there was so much creativity all over the venue that it was really hard to not start to make or hack on something.

While it had many very interesting things to be seen, I think to most amazing machine on the ground was a “Crepes printer”. Some austrian dude built a machine which would make you a fresh crepe. Including some chocolate sauce! Just right next the that were some friends that intend to launch a sattelite and already had their radio equipment ready. With their massive antenna they spoke to the moon and measured the reflections coming back.

The participants also got a fancy badge called “r0ket“. It’s an amazing device and people did awesome stuff with it immediately. Given the presence of 3D printers and lasercutters, people added all sorts of extensions to the r0ket. But some enhanced their r0ket with good old knitting goodness.

The whole CCCamp, taking place on an old russian airbase, was themed very aeronautical so everything was somehow related to space travel or rocket science. It also had many talks on those subjects which I didn’t attend a lot. I was too busy hacking or socialising.

You can only see a tiny fraction of the many artisty stuff it had on the ground. But you do see an old MIG which got pwned along with a spacy car. He got trolled quite well, I’d say but decide for yourself:

You can try to grasp the atmosphere by looking at these areal shots:

You can see some more pictures and press articles in the CCCamp Wiki. The next Camp will be “Observe. Hack. Make. 2013.” and I’m very much looking forward to attend it.

If you want to join the fun, be in the Attraktor, the local hackerspace. The address is Mexikoring 21, 22999 Hamburg, Germany, Europe, Earth, Solarsystem. Find more detailed instruction on how to get there here. The party starts on Friday, 2011-04-08, at 18:00 and runs open end.

We have a page in the local wiki to describe the event and further planning will take place there: http://wiki.attraktor.org/Termin:GNOME-3-Launch-Party. As for the program: We intend to have a small introductory talk to show off what new user experience GNOME-3 will bring to the people. Afterwards, we will distribute GNOME-3 images to be put on pendrives to be able try GNOME-3. Finally, we’ll sit around, have some beers and snacks and discuss about the new and shiny GNOME

Besides the GNOME-3 images, we’ll have GNOME-3 goodies to give away! Thanks a lot to the GNOME Foundation making that possible! So show up early to claim your goodies!

So I expect you to be there

The presented talks were mostly interesting, although I didn’t attend that many. I spent most of the time talking to people or giving (two) talks myself: Security in Mobile Devices and Virtualised USB Fuzzing.

The first one went as expected and I think the attendees enjoyed it very much. Again, talking about technical details that a buffer overflow on x86 involves is not that much fun but I think it went at least alrightish. Slides can be found here.

The second talk was kind of a rehearsal for my final thesis presentation. So I took the chance to prepare myself for Dublin and present brand new stuff^tm. I started off crashing a Linux PC with my N900 and went then to the talk. It was a bit confusing, I guess. But in fairness: It was very late in every sense of the word But I got positive feedback nonetheless so it’s better if you make up your own mind with the slides. Although I don’t think the slides alone are that interesting.

For some reason, people were interested in the commands that I’ve used for the demo:

1. Boot Ubuntu
   /opt/muelli/qemu/bin/qemu-system-x86_64 -enable-kvm -hda ubuntu.img -cdrom ~/ISOs/ubuntu-10.04.1-desktop-amd64.iso -monitor stdio -serial vc -m 1G -loadvm 1
2. Setup Filter

usb_filter_setup /tmp/filter
export PYTHONPATH=~/hg/scapy-com/
python recordingfilter.py /tmp/filter /tmp/phonet.dump

3. Attach device

info usbhost
usb_add host:0421:01c8
sudo chown muelli /dev/bus/usb/002/004

usb_filter_remove
usb_del 0.2


4. Replay

usb_add emul:full:/tmp/filter
cat /tmp/filter.in &
cat /tmp/phonet.dump.out > /tmp/filter.out

usb_del 0.0
kill %%


5. Fuzz (didn’t really work because of a Heisenbug)

python emulator.py --relaxed /tmp/filter /tmp/phonet.dump.combined
python fuzzingemulator.py /tmp/filter webcam.dump
usb_del 0.0


6. Fully Virtualise


usb_add emul:full:/tmp/filter
python usbmachine.py /tmp/filter.in /tmp/filter.out
usb-devices

This years motto was “contruct, desctruct!” and I was more on the destructing side: I presented two topics: Security in Mobile Devices and a Magnetic Stripe Card workshop.

The Security in Mobile Devices talk went quite well and I think I encouraged people to start hacking their devices It’s funny though: I almost see blood coming out of the people ears when I go through the very technical part about buffer overflows. 2/3 seems to be bored or overwhelmed. The other 1/3 seems to be very interested and crave for more details. But I get everybody back when I have more pictures and videos about funny exploits and when I’m able to slander about Apple Again, I talked about a mixture of Hardware and Platform security and gave examples of previous hacks and how to actually start breaking your gadget.

The magnet card workshop was interesting, too. I presented how magnetic stripe technology actually works. And because we were curious hackers, we explored how it’s been used and how we can hack stuff. I told a few warstories that will hopefully be able to expand on in the future (although I don’t know whether DCU will like it ). Since it was more of a workshop, people contributed with technical details (thx to the guys from das Labor ) or other interesting facts.

I had a nice weekend in Dortmund and I can recommend attending the ChaosBBQ if you’re looking for a tiny yet open gathering of interested geeks and hackers.

Was ist das Easterhegg?

Das Easterhegg ist das Oster- und Familientreffen des Chaos Computer Clubs und seiner Freunde. Im Jahr 2010 will der µCCC auf der Flucht vor langweiligen Familienfesten kreatives Asyl im familiaeren Kreise Gleichgesinnter bieten. So wird zum Fest nach Muenchen eingeladen, aber nicht nur das: Bei diesem Fest geht es aber auch darum, konkret an Dingen zu basteln und auch darum, immer ein paar Ecken weiterzudenken.

Erfahrungsgemaess werden in den Workshops sowohl sehr technische, als auch immer haeufiger gesellschaftspolitische Themen behandelt. Gefreut wird sich also ueber skurrile Softwarebastelleien, handgreifliche Loetorgien, Aufdeckung von Verschwoerungungen und spontane Realisierungen einer Utopie – oder auch nur Vorschlaege dazu.
Gern gesehen sind aber auch andere Themen, die bewegen und von denen Ihr denkt, dass sie fuer einige Teilnehmer anregend und spannend sind.

Wann und Wo?

Von Karfreitag 02.04.2010 bis Ostermontag 05.04.2010 im  EineWeltHaus  Muenchen Schwanthalerstr. 80 80336 Muenchen bei 48.156582,11.543541.

Ich glaube, ich werde etwas zu Krypto, Buffer Overflows und Mobile Security machen. Mal gucken

A good way of socialising is, of course, visiting the various parties that take place. The Phenoelit party was awesome. Thanks FX for the invites

Besides drinking I spent time on some crypto problems and tried to investigate on the magnetic-stripe-card authentication in Hotels and Hostels. I found out, that all our cards for one room are equal, but not one card that has been obtained later. The data on the card is just ~100bits and I tried to find timestamps and room numbers in it but I failed. I blame my dataset to be too small. I’ll launch more advanced experiments next year. If you happen to have insider knowledge in magnetic-stripe locks, drop me a line.

I want to highlight two things about the last CCCongress. Firstly, Friend Tickets were available and the concept is just awesome: Basically you can propose a friend of yours you think would benefit of attending the CCCongress but has no way to cover the expenses. The organisers then decide whether you can get a discount (which will, of course, apportioned to every regularly paying attendee). I like to see this solidarity among hackers. Unfortunately, no stats are available to see how many people were enabled to come through this method. I hope, having these friend tickets will be considered next year again. So if you wanted to come to the CCCongress but feared the expenses, consider asking for a discount. Just for the record: The prices are at rock bottom anyway: 80 Euros for a 4 day conference of this kind is amazingly cheap. Thanks to all the angels!

The second noteworthy concept to distribute the CCCongress as much as possible (called Dragons Everywhere). The idea is fantastic: Increase the number of attendees as much as possible by building mini conferences and stream the most important things. It would be even better, if the gatherings had a feedback channel, i.e. Webcam. Hopefully, it’ll be better next year, i.e. better and more reliable streaming services and more places, especially in Berlin, because many people were sent away because the conference was already sold out

If you want to get a feeling of what the CCCongress is like, you might want to have a look at the recordings. If you organize a public viewing, make sure you show these videos Based on the feedback, the best talks were:

• WikiLeaks Release 1.0 (Torrent)
• cat /proc/sys/net/ipv4/fuckups (Torrent)
• The Lost Cosmonauts (Torrent)

And for entertainment, the following German talks are very good:

• Joepardy (Video)
• Fnord Jahresrueckblick (Torrent)
• CCC Jahresrueckblick (Torrent)

I hope you enjoy watching the CCCongress and consider coming in next year!

The people were entertained and hopefully learned something Sadly, the hardware didn’t really work The buzzer were somewhat broken so that we actually had to try to see (with our eyes) who pushed the button first. Funnily enough, I *did* test the setup extensively just 10 minutes before the gig! Very weird.

The Questions can be found here: Round 1, Round 2, Round 3, Round 4. But it doesn’t make much sense without the jOEpardy software, unless you parse the XML on your own.

The software is a Java Application which was initially written by TriPhoenix! I haven’t written Java for a long time and I have to admit, that writing Java with Eclipse is actually fun! Eclipse is so smart and tightly integrated in the build process that it’s quite easy to write, build and debug. I wish there was such a good IDE for C or Python. Sadly, I think that Java Code is bloated although <2.500 LoC for a jOEpardy is not too bad I’d say

I actually thought I could release the jOEpardy code by now (and thus waited with this post…), but I still have to resolve copyright questions.

You might like the inverted version (also as SVG):

There is a modified version which aims to be more like the original RAF logo by mimicking a shotgun (also a SVG):

Datenspuren 2009 Flyer Back

The CCC has built up a great Dome as well as a big tent for hacking. CCCHH brought Milliways, the last pub at the end of the universe and it was a really cool place to hang out. There were many people from different countries which made it really interesting and enjoyable to just be there. Last but not least, the beer was great

Others have brought a GSM Network! How awesome is that?! Harald Welte and his fellow GSM-Tent members have set up the “42″ Network and we were able to place as many (internal) phone calls and SMS as we liked. Of course, we started to script that So I found out, that sending an SMS via a serial connection to my phones modem is as simple as the following lines:

import serial
import time
 
DEVICE = '/dev/ttyACM0'
 
def send_sms(nr, msg):
    ser = serial.Serial(DEVICE, 115200, timeout=1)
    ser.write('AT\r')
    line = ser.readline()
    line = ser.readline()
    assert line == "OK\r\n"
 
    ser.write('AT+CMGF=1\r')
    line = ser.readline()
    line = ser.readline()
    assert line == "OK\r\n"
 
    ser.write('AT+CMGS="%s"\r' % nr)
    ser.write('%s\n' % msg)
    ser.write(chr(26))
    time.sleep(3)
    lines = ser.readlines()
    print lines
    ser.close()

Sadly, I couldn’t hack more with the GSM network because it was shut down rather early and I didn’t use my computer much during the lecture time. So next time I’ll try to reproduce the Curse of Silence and play around with PDU SMS.

So I have been to a lot of interesting villages and I met some interesting people but sadly GNOME people couldn’t make it. Maybe we’ll have a GNOME Village next time… If you are interested in how the camp looked, watch this impressions movie or click through the media.

The next CCCamp will probably be in two years and according to rumours it’ll happen in Finowfurt again. I’m really looking forward to that event!
