Hillbilly Tracking of Low Earth Orbit

Satellites in Low Earth Orbit have tons of nifty signals, but they move quickly though the sky and are difficult to track with fine accuracy. This lecture describes a remotely operable satellite tracking system that the author built from a Navy-surplus Inmarsat dish in Southern Appalachia. Satellites in Low Earth Orbit have tons of nifty signals, but they move quickly though the sky and are difficult to track with fine accuracy. This lecture describes a remotely operable satellite tracking system that the author built from a Navy-surplus Inmarsat dish in Southern Appalachia. The entire system is controlled through a Postgres database, fed by various daemons spread across multiple machines. So when I click on a satellite on my laptop or cellphone, it runs "UPDATE target SET name='Voyager 1';" and the motor daemon then begins to track the new target while the prediction daemon maintains accurate estimates of its position in the sky. Additional daemons take spectral prints or software-defined radio recordings of the targeted object for later review. http://events.ccc.de/congress/2013/Fahrplan/events/5463.html Day: 2013-12-28 Start time: 14:00 Duration: 01:00 Room: Saal 1 Track: Science & Engineering Language: en

Hacking as Artistic Practice

!Mediengruppe Bitnik are contemporary artists. In their talk they will show two examples of their work, illustrating the translation of hacking from the computer field into an artistic practice. Bitnik will show how to hack the opera in ten easy steps and what happens when you send a parcel with a hidden live webcam to Julian Assange at the Ecuadorian Embassy in London. Using the strategies of hacking, !Mediengrupppe Bitnik intervenes into settings with the aim of opening them up to re-evaluation and new perspectives. «Opera Calling» was an artistic intervention into the cultural system of the Zurich Opera. From March 9th to May 26th 2007, audio bugs, hidden in the auditorium, transmitted the performances of the Zurich Opera to randomly selected telephone land-lines in the city of Zurich. In proper style of a home-delivery-service, anyone who picked up their telephone, was able to listen to the on-going opera performances for as long as s/he wanted through a live connection with the audio bug signal. The Zurich Opera launched a search for the bugs and in a first reaction threatened to take legal action if the transmissions were not stopped and the bugs not removed. «Delivery for Mr. Assange» is a live mail art piece. In January 2013 !Mediengruppe Bitnik sent Wikileaks-Founder Julian Assange a parcel containing a camera. Julian Assange has been living in the center of a diplomatic crisis at the Ecuadorian embassy in London since June 2012. Through a hole in the parcel, the camera documented and live-tweeted its journey through the postal system, letting anyone online follow the parcel's status in real-time. !Mediengruppe Bitnik regard this work as a SYSTEM_TEST. Would the parcel reach its intended destination? Or would it be removed from the postal system? http://events.ccc.de/congress/2013/Fahrplan/events/5425.html Day: 2013-12-28 Start time: 19:00 Duration: 00:30 Room: Saal 6 Track: Art & Beauty Language: en

RFID Treehouse of Horror

In this lecture, we present a black-box analysis of an electronic contact-less system that has been steadily replacing a conventional mechanical key on multi-party houses in a big European city. So far, there are est. 10.000 installations of the electronic system. The mechanical key has been introduced about 40 years ago to allow mail delivery services to access multi-party houses but has since then aggregated many additional users, such as garbage collection, police, fire brigade and other emergency services. Over 92% of residential buildings in this city are equipped with such a solution. We have found several vulnerabilities in the new system caused by the design, technology used, organization, and its implementation. We have further shown that the new system is circumventable with little costs (not higher than the old key is sold under the counter). To acquire keys samples we packed an active mid-range RFID reader with a battery pack into a parcel and send it via post. On its way, the reader wirelessly collected the key(s) of the handling personnel. As a side project, we also present security shortcomings in other access control systems and electronic purse solutions. http://events.ccc.de/congress/2013/Fahrplan/events/5334.html Day: 2013-12-29 Start time: 14:00 Duration: 01:00 Room: Saal 2 Track: Security & Safety Language: en

Nature: The original computer whizz

Alan Turing is sometimes called 'the founder of computer science'. To celebrate the 100th anniversary of his birth, Charlotte Stoddart went to Oxford to meet his biographer, physicist Andrew Hodges. In this podcast, they talk about Turing's famous 1936 paper on computable numbers, his contribution to cracking the German Enigma ciphers, and his thoughts on machine intelligence. http://www.nature.com/nature/podcast/index-turing-2012-02-23.html

Die Pick-Up-Artists - Mit Verführungskünstlern auf der Jagd | Freistil | Deutschlandfunk

'Ich tanze eine HB8 an, mein Wing approached die andere. Richtig gute Targets.' Pick-Up-Artist sein, das heißt Frauen aufreißen mit System. Die Verheißung, jede Frau rumzukriegen, wenn man ein paar Psychotricks lernt, macht schüchternen Durchschnittsmännern Hoffnung. http://www.dradio.de/dlf/sendungen/freistil/1501515/
