Tor Ecosystem Presentation
by Damian Johnson 28 Nov '13

28 Nov '13

Hi all. A little over a week ago I gave a presentation at Seattle's TA3M at Ada's Books to give an overview of the projects within the Tor ecosystem. This is a revised version of a similar presentation Roger and Jake gave at 29c3... Presentation: https://archive.org/download/t3am-seattle-nov2013/damian_johnson.mp4 Slides: https://www.atagar.com/transfer/tor_ecosystem/ I'm really startled about how high pitched my voice turned out. Strange I've never heard myself recorded and played back before. That aside, the presentation turned out pretty well. Many thanks to Lee and Chirs (TA3M's organizers) and Mr. Caggiano who recorded the presentation. Cheers! -Damian

What happened to Tor Router?
by SiNA Rabbani 26 Nov '13

26 Nov '13

Hi, I am trying to update myself on the status of Tor Router. I remember not too long ago it was a sexy project, funds were raised and people got paid to work on it. Has it been abandoned? How come we still don't have a Tor hardware router? All the best, SiNA I'm wondering why

Development of an HTTP PT
by dardok 25 Nov '13

25 Nov '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I am quite new in here but I am interested to help and improve the TOR system. I am interested in PTs and particularly in developing a HTTP PT. I've read some papers [0],[1],[2],[3] and the ticket #8676 and I consider that it would be a good idea to make an effort and try to implement the HTTP PT as is stated in the ticket, that is using real browser and server services. After talking with asn, we conclude that a good point to start this development may be to focus on the HTTP transport part, that is to know how to control the browser or the server and how to embed the TOR traffic into the HTTP protocol (requests and responses). Things such as the data obfuscation, the delays in the communications and the packet chopping won't be considered, because it may be used another PT such Scramblesuit to do that task. The CLIENT side: TBB <-> Scramblesuit PT <-> HTTP PT <-> CENSOR NET and the SERVER side: CENSOR NET <-> HTTP PT <-> Scramblesuit PT <-> TOR bridge The important is to know how to embed the TOR traffic already obfuscated into the requests and responses to avoid suspicion. Also as I said before, to know how to control a browser binary to make the HTTP traffic from the client side as much traditional as possible, for instance using a firefox binary or something like that. The same must be applied to the server side, implementing a real NGINX server or an Apache server on port 80 and writting some CGI to classify the traffic incoming from the TOR clients through the HTTP requests. The same server may have another CGI to write and send the HTTP responses to those TOR clients with the traffic into them. I would like to find someone interested to work on this topic. Thanks and I wait for your comments or suggestions!

Good question. You probably want to go to obfsproxy/managed/server.py and obfsproxy/managed/client.py and place a strategic run_transport_setup() hook. I would place it before the launch_transport_listener() call. You might also need to use obfsproxy/transports/get_transport_class() somewhere in there. Another nice thing would be if you could pass the pt_config struct in setup(), so that transports can use pt_config elements during initialization. As an example, see how obfs2 configures its shared-secret in its __init__ using getServerTransportOptions(). That could be done in its setup(), I think. Does this make sense? If you don't want to do this coding, I can do it at some point next week. Cheers! ( And while I'm on it, let me tell you about the different ways that you can pass parameters to obfsproxy. I wanted to document this somewhere, and this thread seems like a good excuse :) - External mode: You can pass global parameters to external mode transports by using the register_external_mode_cli() and validate_external_mode_cli() functions. - Managed mode: - Global parameters: These are parameters that are passed to obfsproxy on startup. - Server: On the server-side we can pass global parameters to obfsproxy by using the TOR_PT_SERVER_TRANSPORT_OPTIONS environment variable. Obfsproxy exposes those parameters using the transport_config struct and obfsproxy/common/transport_config.py:getServerTransportOptions . - Client: On the client-side we don't have a way to pass global parameters to obfsproxy yet. If we ever need to, we can do it with environment variables here too. - Per-connection parameters: These are parameters which are supposed to be different for each connection. An example of such a parameter can be a shared-secret used for a specific bridge connection. - Server: On the server-side we don't have a way to pass per-connection parameters at the moment. - Client: On the client-side we pass per-connection parameters using the SOCKS handshake as a covert channel. Transports can retrieve these parameters using the handle_socks_args() method. )

Fwd: [guardian-dev] Orfox: first step towards Tor Browser on Android
by Nathan Freitas 24 Nov '13

24 Nov '13

First small step towards a true Tor Browser on Android. -------- Original Message -------- Subject: [guardian-dev] Orfox: first step towards Tor Browser on Android Date: Sat, 23 Nov 2013 23:18:30 -0500 From: Nathan of Guardian <nathan(a)guardianproject.info> To: Guardian Dev <guardian-dev(a)lists.mayfirst.org> Since Android 4.4 replaced the guts of the WebView component with Chrome, and there is no apparent way to set a proxy anymore (even through tricks like reflection), I decided to accelerate our move towards an entirely new approach to privacy-enhanced browsing. I discovered two projects that provide a full standalone browser component that you can embed in an app. ChromeView, based on Chromium, and very much a drop-in replacement for WebView: https://github.com/pwnall/chromeview GeckoView, Mozilla's own attempt to turn their browser engine into an Android developer component: http://starkravingfinkle.org/blog/2013/10/geckoview-embedding-gecko-in-your… I started with ChromeView, but got stuck just trying to get it to run. Both approaches require some strange use of putting .so and .pak binaries into asset folders and such. I don't entirely understand why yet. I ended up getting the GeckoView project's GeckoBrowser sample running easily, and very quickly, started hacking in all the privacy-enhancing Firefox "about:config" preferences I know. All the SOCKS and HTTP proxying stuff works well, and I have even gotten to a fairly decent report back on ip-check.info in terms of cookies, referrals, user-agents, etc. You can find the repo here, if you want to build and try yourself. No binaries posted yet: https://github.com/guardianproject/Orfox I am aiming to do a release fairly quickly, at least for the Android 4.4 users who are currently left in a lurch. Otherwise, if anyone wants to help build the best, most secure and privacy-enhancing mobile browser in the world, what we need to do from here is: 1) Start building the GeckoView library from source ourselves, and figure out which components we really need. It is very bloated, and the current APK is humongous. 2) Re-implement Orweb's various preferences into the new Orfox app, so that users can easily choose to turn on/off javascript, clear cookies, and so forth. 3) Connect with Mike Perry of Tor Project and start figuring out how the Firefox patches / modifications he makes for Tor Browser can be applied to the GeckoView builds. Best, Nathan _______________________________________________ Guardian-dev mailing list Post: Guardian-dev(a)lists.mayfirst.org List info: https://lists.mayfirst.org/mailman/listinfo/guardian-dev To Unsubscribe Send email to: Guardian-dev-unsubscribe(a)lists.mayfirst.org Or visit: https://lists.mayfirst.org/mailman/options/guardian-dev/nathan%40guardianpr… You are subscribed as: nathan(a)guardianproject.info

Help me guague how full your plate is via regular check-in conversations
by Tom Lowenthal 20 Nov '13

20 Nov '13

Hello fighters for freedom, When applying for grants, planning future work, and otherwise thinking about what capacity we have leftover to do things in the future, it's really useful to know who's doing what and how much of it. I get some of this information from our sponsor/project-specific meetings, but it doesn't seem to be the full picture, so I'd like to trot out that old chestnut of regular one-on-one chats. This means that I'd like to spend between thirty and sixty minutes talking with each of you, once every week or two. I'd like to calibrate the frequency so that we can get calls down to 30 minutes each, with room to kvetch and have a conversation that's a little more than just rattling off deliverable status and time assignments. I think that the right group for this is the folks who post to tor-reports. If you post to tor-reports, please get back to me by the end of the week with your availability for a regular weekly check-in, as well as any thoughts you have about medium, format, or anything else. If you're not currently on tor-reports and think you should check in, or vice versa, you should probably drop me a line too. Any questions or suggestions? -Tom
