Anti-censorship meeting notes, 3 Oct 2019
by Philipp Winter 03 Oct '19

03 Oct '19

Here's our meeting log: http://meetbot.debian.net/tor-meeting/2019/tor-meeting.2019-10-03-17.00.html And here's our meeting pad: Anti-censorship work meeting pad -------------------------------- Next meeting: Thursday October 3rd 17:00 UTC Weekly meetings, every Thursday at 17:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress). == Goal of this meeting == Weekly checkin about the status of anti-censorship work at Tor. Coordinate collaboration between people/teams on anti-censorship at Tor. == Links to Useful documents == * Our anti-censorship roadmap: https://dip.torproject.org/torproject/anti-censorship/roadmap/boards * Our roadmap consists of a subset of trac tickets. * The anti-censorship team's wiki page: https://trac.torproject.org/projects/tor/wiki/org/teams/AntiCensorshipTeam * GetTor's roadmap: https://dip.torproject.org/torproject/anti-censorship/gettor/boards * Tickets that need reviews: https://trac.torproject.org/projects/tor/query?status=needs_review&componen… * Projects from sponsors we are working on: * https://trac.torproject.org/projects/tor/wiki/org/sponsors/Sponsor30 * https://trac.torproject.org/projects/tor/wiki/org/sponsors/Sponsor28 --------------------------- --- 3rd October 2019 --- --------------------------- == Announcements == * Looks like our new default bridge (just started shipping in the new Tor Browser alpha) is already blocked by the GFW * Do we know whether it happened before or after the release? Before = source code inspection (and they know about the moved tor-browser-build.git repo); after could be source code inspection or package inspection or black-box testing. * Unfortunately not; I only tested it just now * Add the date and time you tested to MetricsTimeline, if you would. * I will! * Also most of our new bridgeDB bridges seem to be blocked: https://trac.torproject.org/projects/tor/raw-attachment/ticket/31701/obfs4-… * Tor Browser files are appearing now at https://archive.org/details/@gettor for gettor purposes. * And also at https://drive.google.com/drive/folders/13CADQTsCwrGsIID09YQbNz2DfRMUoxUU == Discussion == * What research questions can we think of that we should pitch to students? * Study BridgeDB crawling by setting up a variety of bridges (use tor's BridgeDistribution option) and check if they end up getting blocked. * Understand how and whether benign third parties are using/scraping Tor bridges. Research project sketch here: https://bugs.torproject.org/30636#comment:33 * Measure reachability of our snowflake broker (and bridge?) * Reverse-engineer/study a DPI system https://github.com/net4people/bbs/issues/15 * Understand what's happening with reported Shadowsocks blocking in China since mid September. Active probing? Large-scale flow analysis? * Understand the WebRTC fingerprint of pion-webrtc, in the style of https://trac.torproject.org/projects/tor/wiki/doc/Snowflake/Fingerprinting. * Evaluate effectiveness of obfs4's simplistic "slap some padding onto application data" approach * How does sharknado's packet-burst-breaking approach compare? * What is the the "right" packet sending schedule (assuming no restrictions on efficiency)? Where a schedule is an algorithm that outputs a sequence like "wait 50 ms, send 200 bytes, wait 4100 ms, send 1460 bytes, ..." Start by proposing a strawman schedule to give us something to work with. Ideally I would like to see an adversarial analysis: let one team develop a scheduler (using their own collected traffic), and a different team evaluate it (using their own collected traffic). * torproject.org mirrors - what is the right strategy for accepting them? (conversation will continue in a ticket) == Actions == * == Interesting links == * == Updates == FORMAT! Name: This week: - What you worked on this week.

OONI Monthly Report: September 2019
by Maria Xynou 02 Oct '19

02 Oct '19

Hello, Below we share what the OONI team worked on in September 2019. ## Launch of revamped OONI Explorer We launched the revamped version of OONI Explorer! Access the new OONI Explorer here: https://explorer.ooni.org/ Along with the launch, we published a post that explains in detail what's new about OONI Explorer 2.0: https://ooni.org/post/next-generation-ooni-explorer/ We were interviewed by the Committee to Protect Journalists (CPJ), who published a Q&A where we discuss how journalists can use the new OONI Explorer: https://cpj.org/blog/2019/09/qa-ooni-explorer-team-unlock-the-webs-untold-c… VPNCompare also published a blog post about the new OONI Explorer: https://www.vpncompare.co.uk/ooni-explorer-uncovering-global-web-censorship/ ## Report on blocking of BBC and Alhurra in Egypt In collaboration with Egyptian community members, we published a research report documenting the blocking of BBC and Alhurra in Egypt. Our report is available here: https://ooni.org/post/2019-egypt-blocks-bbc-and-alhurra/ Mohamed El-Taher translated the report to Arabic: https://moeltaher.net/2019/09/26/مصر-تحجب-بي-بي-سي-والحرة-التوسع-في-الرق/ In the report, we share network measurement data on: * Blocking of BBC: https://explorer.ooni.org/search?until=2019-09-26&domain=www.bbc.com&probe_… * Blocking of Alhurra: https://explorer.ooni.org/search?until=2019-09-26&domain=www.alhurra.com&pr… We corroborated OONI measurements by performing manual curl tests with the help of our local partners, the findings of which we share in the report. We found that Egyptian ISPs are using Deep Packet Inspection (DPI) technology that is aware of TLS and which is most likely fingerprinting the SNI field of the TLS handshake. VPNCompare published a blog post covering our report: https://www.vpncompare.co.uk/ooni-bbc-blocked-egypt/ ## Updated test lists To help improve the quality of measurements, we updated the following test lists: 1. Algeria: https://github.com/citizenlab/test-lists/pull/517 2. Cameroon: https://github.com/citizenlab/test-lists/pull/508 3. Tanzania: https://github.com/citizenlab/test-lists/pull/520 4. Indonesia: https://github.com/citizenlab/test-lists/pull/512 5. Vietnam: https://github.com/citizenlab/test-lists/pull/516 As part of the process of updating the above test lists, we reviewed all of the URLs (i.e. deleted defunct URLs, replaced old URLs with new ones, added HTTPS where appropriate, etc.), fixed the category codes (i.e. changed category codes where required), and added new URLs based on relevant desktop research. We also made contributions to other test lists: https://github.com/citizenlab/test-lists/pull/514 https://github.com/citizenlab/test-lists/pull/511 https://github.com/citizenlab/test-lists/pull/510 https://github.com/citizenlab/test-lists/pull/509 https://github.com/citizenlab/test-lists/pull/506 https://github.com/citizenlab/test-lists/pull/502 https://github.com/citizenlab/test-lists/pull/501 https://github.com/citizenlab/test-lists/pull/500 ## Progress on implementing new OONI Probe nettests We made significant progress (80%) towards completing the implementation of new OONI Probe nettests. Specifically, we: * Added functionality to measure SNI-based blocking: https://github.com/ooni/netx/pull/11 * Completed the ndt7 client for OONI Probe: https://github.com/m-lab/ndt7-client-go/pull/29 * Re-wrote DASH to use HTTPS: https://github.com/neubot/dash * Extracted timing of network, TLS, HTTP events: https://github.com/ooni/netx/blob/111e220d770f289108af03fc3ee5fdb526e4906a/…, https://github.com/ooni/netx/blob/111e220d770f289108af03fc3ee5fdb526e4906a/…, and https://github.com/ooni/netx/blob/111e220d770f289108af03fc3ee5fdb526e4906a/… * Implemented DoT and DoH: https://github.com/ooni/netx/tree/master/internal/dnstransport/dnsovertcp and https://github.com/ooni/netx/tree/master/internal/dnstransport/dnsoverhttps * Got the content of DNS packets (including the DoT and DoH cases): https://github.com/ooni/netx/blob/111e220d770f289108af03fc3ee5fdb526e4906a/… ## Progress towards stable release of OONI Probe desktop app for Windows and macOS We made progress on getting the OONI Probe desktop app ready for the stable release. Specifically, we: * Completed the implementation of the Web Connectivity measurement screen for the OONI Probe desktop app: https://github.com/ooni/probe-desktop/pull/44 * Added support for dev tools to aid debugging: https://github.com/ooni/probe-desktop/pull/43 * Wrapped strings (that are to be translated) in Formatted message to support translations: https://github.com/ooni/probe-desktop/pull/41 * Upgraded the dependencies of the app to the latest version: https://github.com/ooni/probe-desktop/pull/40 * Fixed some bugs related to upgrade depedencies: https://github.com/ooni/probe-desktop/pull/39 & https://github.com/ooni/probe-desktop/pull/42 The overall progress and next steps towards the stable release of the OONI Probe desktop app can be tracked through our project board: https://github.com/orgs/ooni/projects/4 ## Progress towards stable release of OONI Probe Command Line Interface (CLI) As part of our work towards the stable release of the OONI Probe ClI, we: * Prepared the v0.1.0 release of probe-engine: https://github.com/ooni/probe-engine/pull/62 * Documented the milestones for the stable probe-cli: https://github.com/ooni/probe-cli/milestone/3 ## Progress on OONI Probe mobile apps We continued to make progress towards the public release of OONI Probe mobile v.2.2.0. Android: https://github.com/ooni/probe-android/pull/263 https://github.com/ooni/probe-android/pull/262 https://github.com/ooni/probe-android/pull/258 https://github.com/ooni/probe-android/pull/256 iOS: https://github.com/ooni/probe-ios/pull/308 https://github.com/ooni/probe-ios/pull/307 ## Progress towards reducing the latency of publication of measurements We continued to make progress towards reducing the latency of the publication of uploaded measurements. This can be viewed through our work on the fast-path: https://github.com/ooni/pipeline/pull/213 The fast-path code has been reviewed and it is currently deployed against active OONI Probe collectors. The remaining next step is to add support for returning the realtime measurements via OONI API queries, and to support the searching and listing of these measurements in OONI Explorer. This is work in progress: https://github.com/ooni/api/pull/115 ## Progress on data processing pipeline heuristics for flagging relevant blocking events for the RSS feed To flag relevant blocking events via the RSS feed in OONI Explorer, we created a new data pipeline with an internal web app and API for the publication of charts and we worked on integrating the blocking events into the database. The component implements a new heuristic to analyze past events and infer when URLs become blocked or unblocked with granularity of a country. Current branch and pull request: https://github.com/ooni/pipeline/pull/228 We expect to have the event engine running soon and we'll then work on publishing it on OONI Explorer. ## Ensuring that our infrastructure is re-deployable As part of our efforts to ensure that all our infrastructure is re-deployable, we made progress on the following: * The dom0 bootstrap script has been updated to work with Debian buster: https://github.com/ooni/sysadmin/pull/353 * We dropped the legacy UID scheme to make it easier to deploy machines: https://github.com/ooni/sysadmin/issues/289 * We upgraded matomo to a latest machine, redeploying it: https://github.com/ooni/sysadmin/pull/355 (fixes: https://github.com/ooni/sysadmin/issues/225 & https://github.com/ooni/sysadmin/issues/149) * Grafana was updated to the latest version: https://github.com/ooni/sysadmin/pull/360 The master ticket with all the hosts that need to be re-deployed is available here: https://github.com/ooni/sysadmin/issues/356 ## Improving the availability of our infrastructure We made progress on improving the availability of our infrastructure. Our plan on how to go forward has been documented in this ticket: https://github.com/ooni/sysadmin/issues/359 Our work on oonifying the probe services is available in this pull request: https://github.com/ooni/sysadmin/pull/361 So far, we have deployed a new web-connectivity test helper and we will oonify the bouncer, collector, and orchestra backends into the same host. ## Community use of OONI data ### OONI data supports court case in Pakistan Back in November 2017, we reported on the blocking of several media websites, Facebook (facebook.com and Facebook Messenger), YouTube, Twitter, Instagram, WhatsApp, and Telegram in Pakistan amid protests: https://ooni.io/post/how-pakistan-blocked-social-media/ Our report -- which shared OONI network measurement data collected from Pakistan -- was used as evidence in a petition filed in the Islamabad High Court by Pakistan's Media Matters for Democracy (http://mediamatters.pk/), challenging the blocking of media websites and popular social media platforms during the protests. The petition challenged the Pakistan Telecommunication Authority's (PTA) authority to block websites without due process. Details are available here: http://digitalrightsmonitor.pk/islamabad-high-court-takes-up-petition-filed… The petition was filed through Charahgar (http://mediamatters.pk/charahgar/), a legal aid centre that Media Matters for Democracy established with the support of Media Legal Defense Initiative (MLDI). As an outcome, the Islamabad High Court declared (in September 2019) that the Pakistan Telecommunications Authority's interpretation of Section 37 of PECA is against the Constitution, and that they cannot regulate content without following the due process, the principles of transparency, and oversight. Details are available here: https://tribune.com.pk/story/2061933/1-pta-not-empowered-block-website-ihc/ This is a landmark victory for internet freedom in Pakistan. ### Blocking of change.org in Cuba Through the use of OONI Probe and OONI data, YucaByte (a Cuban non-profit organization) published a report on the blocking of change.org in Cuba: http://www.yucabyte.org/confirman-bloqueo-changeorg-en-cuba/ Their report (including the use of OONI Probe) received the following press coverage: https://adncuba.com/noticias-de-cuba/tecnologia/confirman-bloqueo-de-la-pla… ### Venezuelan partners nominated for 2019 Gabo Award Through the use of OONI Probe and OONI data, IPYS Venezuela (along with Venezuela Inteligente / VEsinFiltro) has been monitoring internet censorship in Venezuela since 2014. They have created a network of volunteer OONI Probe users across Venezuela, who coordinate on measuring and reporting on emergent censorship events. Through the use of OONI data, they have published numerous research reports, documenting internet censorship events in Venezuela on an ongoing basis. Their Intercortados project (https://ipysvenezuela.org/intercortados/) has been nominated for the 2019 Gabo Award, among the 10 best innovation projects.

Anti-censorship team monthly report: September 2019
by Philipp Winter 01 Oct '19

01 Oct '19

Hi everyone, Here's what the anti-censorship team has been up to in September: Snowflake ========= - Snowflake will be part of the upcoming Windows version for Tor Browser: <https://bugs.torproject.org/25483> - Moved from the Chrome WebRTC standalone library to the Pion/WebRTC library in our proxies and clients. obfs4 ===== * Published a prototype of sharknado: a flow obfuscator for obfs4 (and other pluggable transports). Sharknado is a net.Conn wrapper that injects padding traffic to thwart traffic classification attacks. Here's some more info: <https://bugs.torproject.org/30716#comment:10> * Improved obfs4 bridge setup guides. Thanks to several volunteers who spotted issues in our guides and contributed new guides! * Updated our obfs4 Docker image to the new Debian buster. Made our image's "latest" tag point to the latest version, which is currently 0.2: <https://bugs.torproject.org/31692> Thanks to a volunteer, we now have a list of usability issues that we will tackle soon: <https://bugs.torproject.org/31834> BridgeDB ======== * Removed the email link to frontdesk@tpo from BridgeDB's landing page and added links to our documentation: <https://bugs.torproject.org/28533> Released BridgeDB version 0.8.2 after the merge. * Worked on syncing BridgeDB's usage metrics over to the metrics team: <https://bugs.torproject.org/19332> * Made lots of progress on updating BridgeDB's requirements.txt file: <https://bugs.torproject.org/29484> Got to a point where all unit tests pass with up-to-date libraries. * Started working on a specification for BridgeDB's usage metrics: <https://bugs.torproject.org/31780> * Started experimenting with a language switcher for BridgeDB: <https://bugs.torproject.org/26543> * BridgeDB's assignments.log file are now archived by CollecTor again: <https://collector.torproject.org/archive/bridge-pool-assignments/> This allows bridge operators to see over what mechanism their bridges are distributed: HTTPS, email, moat, or manual. <https://bugs.torproject.org/29480> GetTor ====== * GetTor now uses the Internet Archive and a Google Drive folder to distribute Tor Browser links. Give it a shot by sending an email to gettor(a)torproject.org and write "windows", "osx", or "linux" in the email's body. * Updated documentation and added nagios check to monitor GetTor's email responder. Outreach ======== * Worked with new obfs4 bridge operators who set up a bridge as part of our bridge campaign: <https://blog.torproject.org/run-tor-bridges-defend-open-internet> So far, we are counting 82 new bridges. Thanks to everyone who participated! * Provided an NGO with private obfs4 bridges for distribution among its users. We are working with a set of operators to set up new, reliable, and fast private bridges, so we can help other NGOs: <https://bugs.torproject.org/28526> Miscellaneous ============= * Deployed a set of new default obfs4 bridges thanks to Tobias Pulls from Karlstad University: <https://bugs.torproject.org/31164> * Fixed a number existing papers and added a WebSci'18 paper to CensorBib: <https://censorbib.nymity.ch> * Fixed outdated documentation on "BridgeDistribution" in tor's man page: <https://bugs.torproject.org/31807>
