Seit einem Monat betreibe ich torservers.net, und jetzt ist an der Zeit einen Blick zurück zu werfen.

QUOTE: Deutschland wehrt sich gegen die Digitalisierung seiner Gesellschaft, während Google ungerührt weiter in die Zukunft investiert: Recorded Future, ein Startup das Vorhersagen über die Zukunft trifft, zeugt von einem euphorischen Innovationsbegriff, den wir auch hierzulande dringend brauchen.

QUOTE: "Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather."
"We will create a civilization of the Mind in Cyberspace. May it be more humane and fair than the world your governments have made before."
A Declaration of Independence of Cyberspace, John Perry Barlow/EFF, 1996
I've been playing with the latest release of I2P for a while now, and I must say that I really like it. I2P is an onion-routing network, decentralized, anonymous, fully encrypted, somewhat like Tor. While the focus of Tor is on anonymous surfing and publishing on the "regular Internet", I2P wants to be "a new network", with network-internal services and lower latency than Tor thanks to a packet-based approach. Tor's FAQ states that "I2P should really be seen as the dual of Tor. Basically every engineering decision Tor has made, I2P made the opposite."
Once you install and run (Java based) I2P you can configure and use it though a convenient local web interface, which already contains a webserver ready for anonymous content publishing, a webmail client, a Bittorrent client and a lot more. It works out of the box for most systems. Currently, they're working on integrating Tahoe-LAFS, a decentralized redundant data storage. The long-term idea is to be able to share some of your own drive space (of course fully encrypted), like you can already conveniently share bandwidth now.
Most fascinating for me is to be able to participate in the formation of a new network. Now that the basic protocols are stable, what it needs is people who set up services within the net, and hobbyists who want to help form a new network. To me, it feels a lot like Internet in the 90s. So, if you also think that the Internet is being destroyed by commercial greed, (re)hyped technologies and buzzwords, join the fun (and #i2p on IRC).

Bei einem Hackerangriff auf das amtliche Register für Emissionshandel sind möglicherweise Verschmutzungsrechte im Millionenwert gestohlen worden. (...) 'Der Angriff war hochprofessionell', sagte ein Mitarbeiter der Deutschen Emissionshandelsstelle (DEHSt) in Potsdam. Das Bundeskriminalamt ist eingeschaltet. (...) Nach Informationen der "FTD" täuschten die Betrüger in einer E-Mail an mehrere europäische sowie einige japanische und neuseeländische Unternehmen eine Mitteilung der Potsdamer DEHSt vor. Darin habe es ironischerweise geheißen, zur Abwehr drohender Hackerangriffe müssten sich die Empfänger neu registrieren."

Ich hatte einen Tor-Exit-Node betrieben für einige Tage und bei meinem Provider (netcup.de) flatterte natürlich ein DMCA takedown notice herein. Wegen eines Torrents, von dem sie ( "CBS Corp" nicht netcup...) die Metadaten gefunden haben. Netcup hat danach meinen vServer runtergefahren - und mir ne Rechnung über 192€ plus Drohung, mich anzuklagen, würde ich nicht innerhalb von 24h CBS die gewünschte Antwort schicken plus der Bemerkung, für jede angefangenen 15 Minuten Arbeit, die sie hätten, würden sie mir weitere 20€ in Rechnung stellen.

An old friend of mine has sketched a picture of me because I am always keeping him (and others) up-to-date on privacy and surveillance news in our school forum.

Thanks Butz! Great artwork!

"PET-CON 2009.1
an informal workshop on Privacy Enhancing Techniques
March 24-25, 2009, Dresden, Germany
PET-CON is a convention to help junior researchers, master and diploma students, to come together and exchange ideas. For this purpose, we're
holding this event every six months at an easily reachable location somewhere in Germany or nearby.
The convention is organized according to the grass roots approach: from young researchers for young researchers. Therefore, there is no formal
dress code, no filtering of contributions, and no participation fee. If possible, we plan the convention in a way which allows people to travel
there and back home on the same day -- so that busy people can participate as well.

The onion routing project Tor has published a three-year development roadmap. It contains a lot of interesting material and research topics, like a mechanism to turn reliable clients into bridges/relays automatically, and 'bonus points' for well-behaving relays.

One of the largest "identity thefts" in German history turned out to be a bizarre christmas story: Account data of 130,000 customers of the Landesbank Berlin (LBB) was delivered to the Frankfurter Rundschau (a German newspaper) on December 10th - allegedly even including PINs.
How did this happen? It was all about Stollen, a traditional German christmas fruitcake.

Quite a few things happened this month in regard to privacy. I highly recommend the 24C3 Conference Talk about Tor to all german readers. Tor allows oppressed citizens of censoring countries such as China and the USA (see below) to bypass filters and surf anonymously, but only with your support (see "related links"). It is not yet clear whether german Tor nodes will be required to log IP data next year as a result of the new data retention law passed in December, which will effectively kill most of them (the amount of data collected over a period of 6 months will be several terabytes). The Chaos Computer Club argues that Tor and similar anonymity services cannot be seen as communication providers and thus are not affected by the law, the Arbeitskreis Vorratsdatenspeicherung isn't so sure about that. We'll see.
One month after Austria has passed a new controversial security law (Sicherheitspolizeigesetz) which allows police to access provider data (including cellphone location and IPs) without the consent of a judge, the left wing party Die Grünen set up a video/blogging platform to monitor Home Secretary Günther Platter, PlatterWatch. More importantly, they published a draft form of Viennas police, which in it's current form allows up to 30 queries at once and supports police officers with clearly illegal requests, for example for IMSI information. The party argues that with the responsibility to decide if a request is legal in the hands of the provider - who might be faced with hundreds of requests - this will certainly lead to abuse.
Video surveillance is another hot topic in Austria at the moment. While many attorneys state that more than 100.000 video cameras are currently being operated without legal grounds, the Ministry of Transport plans to monitor highways and automatically detect car types and license plates in one central police database. Also, federal government is looking into "suitable legal foundations for public video surveillance by individuals".
On a side node: AT&T is preparing to filter internet content for copyright violations.
I have cited a few more privacy related news from Heise Newsticker in the german version of this article for all german readers.
