I am asking because of ticket #25902. Android accessibility services allow password managers to listen for user events. e.g. typing a password in a login form. -Upcoming releases -What is our way forward with our extensions for ESR60? [sysrqb and arthuredelstein will look next week into what is needed to get our extensions integrated into a working ESR60 build] mcs and brade: Last week: - Helped with triage of incoming tickets. - Continued rebasing Tor Browser updater patches for ESR60 (part of #25543). - Tested on macOS. - Participated in the UX/Tor Browser "sync" meeting. This week: - Finish rebasing Tor Browser updater patches for ESR 60. - Test on Linux. - Test on Windows. - Monitor #25807 (Can not request bridges from torproject.org (App Engine is broken for moat)). igt0: Last week: - #25810: Backported few fixes affecting Orfox to tor-browser-52.7.3esr-8.0-1. - #25974: Make sure Android Oreo(API level 26) autofill feature is disabled (looks like it doesn't work on FF, i am trying to make autofill to work on simulator to be 100% sure) This week: - Review and smoke test rebased Orfox patches branch. - Build and test on android the rebased tor browser patches for ESR60 to make sure we are not going to have problems in the alpha release. tjr - Found and bypassed a crash bug for MinGW. Looking at two, maybe three crashes currently. - 1) A crash in https://searchfox.org/mozilla-central/source/nsprpub/pr/src/threads/prtpd.c… that happens on TC - 2) This assert: https://searchfox.org/mozilla-central/source/layout/svg/nsSVGIntegrationUti… - Have been learning more about debugging symbol-less (in WinDBG). Feel pretty comfortable identifying where I am in assembly (assuming Debug asserts are present...) [GeKo: Do you feel you could write up what you learned and, say, add this to the Hacking doc we have? I guess this would help us a lot, too.] - Wrote it up at https://trac.torproject.org/projects/tor/wiki/doc/TorBrowser/Hacking/Debugg… GeKo Last Week: - wrote a patch for the rustc cross-compilation for Windows - fixed the rustc cross-compilation for macOS (still need to clean-up the patch for review) - helped with Sponsor4 reports (yes! those were still a thing!1!) - wrote/backported small patches for tor-launcher (getting Moat to work again) and for tor-browser (fixes an off-by-one error) - started to review the patch rebase for ESR 60 - gave the circuit display patch (#24309) another round of testing - patch reviews/merges (#25898, #25458, #25810, #25973) This week: - finish up the rustc compilation patch for macOS - rebase review - update macOS toolchain - plan to take days off (5/1 and 5/3+5/4) boklm: Last week: - patches for #25817 (add ansible roles for nightly builds) and #25318 (adding email notification for nightly builds) are now ready for review - installed some VMs for running the Tor Browser testsuite, and started working on some ansible roles for the setup - worked on a patch for #25876 (Source release tarballs for Tor Browser) to automate creation of source tarballs - worked on #25862 (Clean up wrapper script/CFLAGS and friends mix on Windows) which is now ready for review - investigated the reproducibility issue with #16472 (binutils update) - started reviewing #25894 (Get a rust cross-compiler for Windows) and #25832 (Enable pthread support for mingw-w64) This week: - help with building the new releases - continue investigating issue with binutils update (#16472) - continue work on testsuite VMs setup sysrqb: Last week: - Worked on TBA patch rebase (#25741) - Worked on updating Orfox's https-everywhere addon (#25603) This week: - Found -8.0-1 branch is busted when building Orfox, fixing now (#25980) - Merge #25603 after we fix bustage - Continue testing #25741, put in needs-review - Start working on another TBA ticket pospeselr: Last week: - Worked on #23247 (Communicating security expectations for .onion), most of the way there but need to plumb down some logic exposing mixed-mode info for .onion to work correctly This Week: - Finishing up #23247 - Entertaining Shane this afternoon - Flying to the east coast to visit family Friday afternoon arthuredelstein: Last week: - https://trac.torproject.org/25938 (backport 1334776) - Updated https://trac.torproject.org/25543 (Rebase Tor Browser patches for ESR60) - Revised patch for https://trac.torproject.org/24309 (Activity 4.1: Improve how circuits are displayed to the user) - Revised patch for https://trac.torproject.org/22343 (Save as... in the context menu results in using the catch-all circuit); will post after more testing - Did more cspace calculations for https://trac.torproject.org/25575 (Server space request for hosting Tor Browser downloads) updated by arthuredelstein This week: - Try to get a preliminary desktop build working for TBB/ESR60 - Continue revising https://trac.torproject.org/25543 branch - Permissions patch revision: https://bugzilla.mozilla.org/show_bug.cgi?id=1330467 Georg

OONI Monthly Report: April 2018
by Maria Xynou 30 Apr '18

30 Apr '18

Hello Tor, The OONI team published a report on network disruptions in Sierra Leone and established a new partnership with a local human rights organization in South Sudan. We also updated more test lists based on research, and we continued to make progress on probe orchestration, the development of the Windows app, and on the revamping of our mobile apps. We experimented with creating and publishing our first short documentary, and we continued to collaborate with community members on tracking censorship events worldwide. # Established new partnership We are excited to have formally established a new partnership with South Sudan's The Advocates for Human Rights and Democracy (TAHURID). As part of our new partnership, we aim to collaborate on the study of internet censorship in South Sudan through the collection and analysis of OONI Probe network measurements. Social media announcement: https://twitter.com/OpenObservatory/status/988695263274586112 # Updated test lists We carried out research (https://ooni.torproject.org/get-involved/contribute-test-lists/#test-list-r…) <https://ooni.torproject.org/get-involved/contribute-test-lists/#test-list-r…> to identify more URLs to test for censorship in Zimbabwe and Venezuela. Based on this research, we updated the following test lists: * Zimbabwe: https://github.com/citizenlab/test-lists/pull/327 * Venezuela: https://github.com/citizenlab/test-lists/pull/329 Overall, based on research, we have updated the following 5 test lists over the last months: * Zimbabwe: https://github.com/citizenlab/test-lists/pull/327 * Venezuela: https://github.com/citizenlab/test-lists/pull/329 * Sierra Leone: https://github.com/citizenlab/test-lists/pull/320 * Egypt: https://github.com/citizenlab/test-lists/pull/336 * Mali: https://github.com/citizenlab/test-lists/pull/304 During April 2018, we also updated the following test lists based on URLs provided by community members: * Kazakhstan: https://github.com/citizenlab/test-lists/pull/330 * Ethiopia: https://github.com/citizenlab/test-lists/pull/326 * Venezuela: https://github.com/citizenlab/test-lists/pull/333 * Uganda: https://github.com/citizenlab/test-lists/pull/334 # Report on network disruptions in Sierra Leone We collaborated with Sierra Leone's Campaign for Human Rights and Development International (CHRDI) to monitor censorship events during the country's election period. OONI data collected and analyzed from Sierra Leone did not show any significant signs of internet censorship. Even though WhatsApp and Facebook Messenger were accessible, their testing presented high execution time, indicating some form of performance degradation on the network. Amid Sierra Leone's runoff elections, two network disruptions occurred. We examined these disruptions via Google traffic and BGP data, and published a report: https://ooni.torproject.org/post/sierra-leone-network-disruptions-2018-elec… # Progress on Probe Orchestration We made a lot of progress on implementing probe orchestration for automatically running network measurements on mobile OONI Probe. See: https://github.com/ooni/orchestra Some highlights include: * Integrating the experiment signing with the Yubikey 4 hardware security module * Significant refactoring of the codebase to make it easier to separate the alert push notification logic from that of experiment notification * Renaming of Proteus to OONI Orchestra * Upgrading the web frontend to the latest dependency versions The unmerged branch containing the above changes is the following: https://github.com/ooni/orchestra/pull/44 # Progress on the Windows app development In collaboration with Simone Basso, we iterated on integrating Measurement Kit into the Windows OONI Probe desktop app (https://github.com/measurement-kit/go-measurement-kit/tree/feature/windows+… <https://github.com/measurement-kit/go-measurement-kit/tree/feature/windows+…>) <https://github.com/measurement-kit/go-measurement-kit/tree/feature/windows+…>. # Revamping the OONI Probe mobile apps As part of our work on revmaping the OONI Probe mobile apps, we continued to make progress on the design and UI, and we released a new testflight for iOS which includes new copy and all of the strings. We also created a design brief for new illustrations to be included in the revamped mobile apps, and we started working with illustrators. # Short documentary on internet censorship in Cuba We published a short documentary that we created during our trip to Cuba last year, titled: "ParkNet: Exploring Internet Censorship in Cuba". This 5-minute film features some of our key findings on our study of internet censorship in Cuba and is available here: https://ooni.torproject.org/post/parknet-short-documentary-cuba/ More in-depth findings are available via our research report (https://ooni.torproject.org/post/cuba-internet-censorship-2017/) <https://ooni.torproject.org/post/cuba-internet-censorship-2017/%29>. This short documentary is our first experiment in presenting censorship findings with video. We have set up an OONI YouTube channel where we plan to publish more videos in the next months: https://www.youtube.com/channel/UCQhDgj9wBf4_w5bWFvLlq-w # Community use of OONI data ## Blocking of IM apps in Chad OONI data was referenced in Internet Sans Frontieres' press statement regarding the blocking of WhatsApp, Facebook Messenger, Viber and BCC in Chad: https://internetwithoutborders.org/chad-is-blocking-social-media-and-messag… ## Blocking of news outlet in Venezuela OONI data confirmed the blocking of news outlet El Pitazo in Venezuela. We provided an analysis and interpretation of measurements that supported IPYS Venezuela's report on the blocking: https://ipysvenezuela.org/alerta/dos-medidas-de-censura-han-afectado-a-el-p… ## Citizen Lab Netsweeper report OONI data was used to identify blocked websites and middleboxes in the Citizen Lab's research report, "Planet Netsweeper": https://citizenlab.ca/2018/04/planet-netsweeper/ # Community activities ## OONI presentation at the International Journalism Festival (IJF) On 13th April 2018, OONI was presented at the International Journalism Festival (IJF) in Italy on a panel that discussed the many faces of censorship. More information about this panel is available here: https://www.journalismfestival.com/programme/2018/states-companies-algorith… The OONI presentation can be viewed here: https://www.youtube.com/watch?v=PTecjRM8tAs&feature=youtu.be&t=11m56s ## Blog post on recent participation at conferences We published a blog post on our recent participation at conferences in Africa, India, and Europe. Our blog post is available here: https://ooni.torproject.org/post/ooni-in-africa-india-europe-conferences/ ## Community meeting We hosted our monthly community meeting on 24th April 2018. As part of the meeting, we discussed the following: 1. Recap of what OONI has been up to over the last month 2. Outreach: How to communicate OONI Probe more effectively and engage wider audiences 3. Community engagement challenges: Monitoring censorship events in Chad and elsewhere in Africa # Userbase In April 2018, OONI Probe was run 265,001 times from 4,911 different vantage points in 210 countries around the world. This information can also be found through our stats here: https://api.ooni.io/stats ~ The OONI team. -- Maria Xynou Research and Partnerships Coordinator Open Observatory of Network Interference (OONI) https://ooni.torproject.org/ PGP Key Fingerprint: 2DC8 AFB6 CA11 B552 1081 FBDE 2131 B3BE 70CA 417E

I'm waiting on feedback on one ticket before releasing. I will probably just release if I don't hear back this week from the author of the patch. - Some work happened in the bad-relays world as well. * This week: - I'll try to finalize with nickm some roadmap items we've been working together (#25500 master ticket). - Short list of bugs for 034: #25761, #25577 - If possible, continue modularization work with #25610 - No rotation role for me this week. catalyst: * last week (2018-W16): - reviewed updates to #25511 (getinfo current-time/*) - control-spec.txt changes to support #25511 (getinfo current-time/*) - also some spec spelling fixes (#25871) caught during review - reviewed #25727 (bool in rust ffi) [*isis, were you able to poke rust people about stuff?*] - did some thinking about #25756 (loosening "consensus from the future" tolerance) with input from nickm - sponsor8 reporting stuff - expense accounting stuff * this week (2018-W15): - code review - continue working on #25061 (spurious connection warnings logged by relay) - look more at #25756 - other 033 or 034 work as needed ahf: Last week: Sponsor 8: - Moved our test s8 onion to a new host. Did some minor tweaks to our site. - Looked at Isa's S8 reporting. - Cross compiled Tor/Orbot for Android-ARM64. Now running Orbot locally with that for test (#25496). Misc: - Progress on #25245: easy to trigger if you inject a lot of traffic to an exit in a Chutney network, but difficult to trigger otherwise. Worked on making it easier to debug. - Go over the interview content with the version2 journalist about Tor. - Participated in a radio show with a host I know from BornHack about Tor. - Think(hopefully?) managed to solve logistics around being able to go to Mozilla All Hands after Seattle. Now waiting for OK from Mozilla. - Reviewed #25140 This week: Sponsor 8: - 0.3.4 work: either network idleness controller interface or conditionally compiled modules. - Talk with Hans about what we need to do to get #25496 (0.3.4 ARM64 work) into an Orbot release. Misc: - Land patches for #25245 (0.3.3). - CI duty. Question: our Jenkins have looked very sad, should I prioritize some time on this during the week? asn: Last week: - Participated in meeting on 2-guards (prop#291). - After the meeting, I submitted a patch for #25843 as was arranged and started testing the 2-guard proposal. I also posted a pseudo-proposal on a possible future for path restrictions in: https://lists.torproject.org/pipermail/tor-dev/2018-April/013085.html - Worked on improving the vanguard simulator, fixing bugs found by mike, and implementing more features (#23978). - Reviewed #24688 and #23693. - Started a thread on replay protection and ed25519 malleability as part of #25552. Ian suggested some possible avenues which I think are worth following. Isis also suggested some alternative avenues based on xeddsa and vxeddsa. I plan to read more into these generalized DSA protocols this week and decide if we can fit them for 034, they seem quite interesting. Perhaps a plausible approach would be to do Ian's simple approach for now, and switch to vxeddsa in the future. Not sure. I plan to read more about this this week, I find it very interesting. - Will be secondary mentor for the ahmia project in SoP this year. This week: - Continue work on 2-guard proposal and vanguards. - Read more about vxeddsa for #25552. - Test haxxpop's hsv3 client auth - Suggest some tasks for the Ahmia SoP student. - More reviews. haxxpop: last week: - Finish the client auth in the v3 onion service (excluding the intro auth) and it's ready for testing now! ( https://github.com/torproject/tor/pull/36 ) You can test it by adding `HiddenServiceAuthorizeClient basic <client_name>` on the service torrc and `HidServAuth <onion address> <base64-encoded x25519 private key>` on the client torrc You can get the private key from `client_authorized_privkeys/<client_name>.privkey` on the service file directory *Could anyone test it soon and, if possible, add it to the next release?* [asn: Yes I will definitely test and start the review procedure! Did you also do intro auth or just desc auth?] [haxxpop: just desc auth, because I still don't know which file to put clients' ed25519 public keys] [asn: ok we can figure this out. i guess you'd like us to give it initial review/testing before doing intro auth, right? makes sense.] [haxxpop: yes. In fact, I think desc auth and intro auth are independent features. We can launch the desc auth without intro auth, if we want. ] - next week: - - Probably take a break ;) pastly: last week: - started testnet authority and convinced people to trust it - feed sbws testnet results to the authority - changed sbws v3bw file units from bytes to KB so they'd be comparable to torflow - faq additions, glossary - sbws scanner (client) performs periodic reachability tests for sbws servers - sought input from dirauths about running sbws servers vs changing sbws to use http servers - signed up to mentor juga for bw scanning work - publish sbws docs at http://d7pxflytfsmz6uh3x7i2jxzzwea6nbpmtsz5tmfkcin5edapaig5vpyd.onion/ this week: - (today, definitely) *make sbws open source** [asn: boom!!!]* - see https://github.com/pastly/simple-bw-scanner - publish sbws docs at readthedocs - unit tests - probably change from requiring sbws servers to using http(s) isis: last week: - reviewed a patch to do `make distcheck` on travis #25814 - reviewed a patch to use coveralls from travis #25818 - did the hook/account setup for getting coveralls to start publishing to https://coveralls.io/github/torproject/tor - revised patches to expose our RNG in rust #24660 - responded to code review on #24659 - lunch meeting with trevor perrin about malleability in HS crypto and hash domain separation in post quantum key exchanges - reviewed #25515 again - long emails to lists about TROVE-2018-005 and HS crypto malleability #25552 - more work on wide create cells #25647 this week: - finish #25647

want to help review Tor training materials?
by Alison Macrina 17 Apr '18

17 Apr '18

Hi all, I'm working on a set of modular training resources for teaching about Tor. They cover a number of common topics (Tor basics, Tor Browser and features, Tor Browser in-depth, Tor mobile, Tor censorship circumvention, and anonymous sharing with Tor) and can be used separately or in conjunction in training environments. These materials will eventually be available to download from community.torproject.org, and we'll be using them to complete some of our usability and outreach work over the next few months. I'd love if some people on this list who give Tor trainings would take a look at the materials I've already created. Right now I've only got slide decks, and I'd like people to look at them and give me feedback before I write the accompanying teacher's manual. If you're interested in giving feedback please contact me offlist and I'll send you the files. Once they're finished, and before community.torproject.org is ready, they'll live on gitweb.torproject.org. Thanks for your help! -- Alison Macrina Community Team Lead The Tor Project
