Chinese research grant 2023YFB3106700, "Research on Generalized Security Theory for Dark Web Suppression"
by David Fifield 29 Apr '26

29 Apr '26

The National Key R&D Program (国家重点研发计划) is a major national-level research funding program in China since 2016. https://zh.wikipedia.org/wiki/%E5%9B%BD%E5%AE%B6%E9%87%8D%E7%82%B9%E7%A0%94… https://www.eeas.europa.eu/sites/default/files/1.pdf#page=59 The National Key R&D Program, and specific grant numbers thereof, are frequently acknowledged in research papers. But finding information beyond the grant numbers is difficult. There's no central public source of grant metadata such as the title, the name of the principal investigator, the start and end dates, and the funding amount. MERICS has published at least one report with aggregate statistics about Key R&D projects (https://merics.org/en/report/controlling-innovation-chain#2-research-projec…) but apparently the sources of data they used are no longer available. But sometimes information about grants gets out through other sources. An example is grant number 2023YFB3106700, which appears in the CV of a researcher named Cao Jie with start and end dates that the English title "Research on Generalized Security Theory for Dark Web Suppression". https://jiejaycao.github.io/CV_Jie.pdf https://web.archive.org/web/20260421165501/https://jiejaycao.github.io/CV_J… https://github.com/JieJayCao/JieJayCao.github.io/blob/b9c4ff3f8e2d4cbe5253b… > Research on Generalized Security Theory for Dark Web Suppression > Nov. 2013 – Dec. 2024 > Researcher, National Key R&D Program of China (Key Special Program), Grant No. 2023YFB3106700 We can do a web search to find research publications that have been funded by this "dark web suppression" grant. I found 6 published papers and 1 preprint: "TorHunter: A Lightweight Method for Efficient Identification of Obfuscated Tor Traffic Through Unsupervised Pre-training".

I'm highlighting it just because I found a title for it, which is rare.

Snowflake relays
by Q Misell 27 Apr '26

27 Apr '26

Hi all, Whilst working on a project the thought crossed my mind that it would be useful to me (the exact reasons as to why aren't relevant here) for a web browser to be able to run a Tor client entirely in the browser, that is using a wasm build of Arti or my own Torrosion library. Obviously, a browser can't just go start making random outbound TCP connections, for good reasons. But what a browser can do is make outbound WebRTC and WebSocket connections, which brought me to Snowflake. At least in most situations, I would have no need for the whole WebRTC infrastructure of Snowflake, as the browser is not *usually* restricted from making a WebSocket connection. So, naturally I looked at the Snowflake source code to see how one would implement that, to discover some things I'm a little confused by. Firstly, the Tor node that the broker hands out seems to be a) hard coded and b) just the one (https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow…) Secondly, the number of active relays offering WebSocket connections are a grand total of 4 (https://metrics.torproject.org/rs.html#search/transport:snowflake?fields=tr…) Therefore, my question to those more knowledgeable is: why is this situation considered acceptable? Why is such relay centralisation fine? Is it even fine? Mit freundlichen Grüßen, Q Misell (sie/ihr - she/her) 🌲 Please consider the environment before using AI to process this email. -- Max-Planck Institut für Informatik Fon +49 681 9325 3547 Forschungsgruppe Internet Architecture (INET) Campus E1.4 514, 66123 Saarbrücken

disrupted service: GitLab CI containers failures
by Antoine Beaupré 20 Apr '26

20 Apr '26

Hi, The GitLab Container Registry is refusing requests to GitLab CI pipelines between projects. This started on Friday, when the GitLab 18.11 upgrade was deployed. We are hoping for a quick fix from upstream, but in the meantime, we need your help! Normal GitLab operation should be unaffected. GitLab CI still works, it just fails with images from our own registry when accessed from personal projects. We've found a workaround that requires you to report the failures to us. In [tpo/tpa/team#42595], we ask that you write a new comment with the following information: - source project: failing project (e.g. `group/failing_project`) - registry project: project it is trying to pull from (e.g. `tpo/tpa/base-images`) - example failed job: URL of the failed job [tpo/tpa/team#42595]: https://gitlab.torproject.org/tpo/tpa/team/-/work_items/42595 For example, this was our first report: > - source project: Diziet/arti > - registry project: tpo/tpa/base-images > - example failed job: https://gitlab.torproject.org/Diziet/arti/-/jobs/1485144 You might be able to fix this yourself. If you have access to the "registry project" above, you can manually add the source project to the CI/CD job token allowlist of the registry project", by following: 1. Settings 1. CI/CD 1. Job token permissions 1. add the "source project" to the allowlist You MUST keep track of that exception and remove it once this incident is resolved! Thank you for your attention! -- Antoine Beaupré torproject.org system administration

gitlab 18.10 upgrade removes "issues"
by Antoine Beaupré 20 Apr '26

20 Apr '26

Hi, Today, we upgraded gitlab.torproject.org to 18.10! Among a couple of interesting new things[1], GitLab introduced a *significant* change in the way "issues" are presented and organized. It was introduced as "the work items list and saved views"[2]. It's an interesting feature! It allows you to see epics alongside issues and create saved searches of your issues, pretty neat. Except. They essentially *removed* the entire "issues" UX. You know how I keep bugging people to "file an issue"? That "new issue" button is gone. Heck, the "issues" button itself is gone. In its place, there is a "work items" button, and *there* you can find your good old issues (and, now, also epics). But, crucially, there's no "Closed" tab anymore, so you can't easily go into closed issues with one click: you need to go through the search form and a couple of clicks to find closed issues. So after consultation (well, really, it was sheer panic) with my colleagues, I found a way to revert this. So you won't yet see this view. If you really want to experiment with it, replace the "issues" string with "work_items" in URLs, that still works. I have filed a comment (like dozens of other GitLab users) objecting to the change, alongside with the instructions for other GitLab administrators to revert this change.[3] It is my hope that the feature can be improved to some maturity (at *least* keep a "closed" tab and a "new issue" button?!) and that eventually we'll be able to switch the feature back on. I can see the point of having a common view for issues and epics, even though it's not a problem I have personally struggled with in GitLab. But at this point, we can't just do that switch. Let me know if there's any other concern here! a.

User Support Report for March 2026
by ebanam 11 Apr '26

11 Apr '26

Hello everyone, This is the report from user support team for the month of March 2026. Note: (↑), (↓) and (-) are indicating if the number of tickets we received for these topics have been increasing, decreasing or have been the same from the previous month respectively. - Summary of updates from user support - General user support - Farsi-speaking user support - Russian-speaking user support - Frontdesk (email user support channel) - Telegram, WhatsApp and Signal user support channels - Highlights from the Tor Forum - Highlights from Google Play Store # Summary of updates from user support ## General user support * 486 tickets in total (↓110 as compared to February) * 319 tickets on Email * 118 tickets on Telegram * 24 tickets on Signal * 25 tickets on WhatsApp * With Tor Browser 15.0.7 release, a potential fix was shipped for the long-time persisting issue about the [Tor daemon failing in the background][] when using Tor Browser for Android. After a month of reviewing Google Play Store reviews and comments and monitoring our user support channels, I am happy to report the issue seems to have been fixed \o/. * With Tor VPN beta now available to download from F-Droid App Store, we updated the documentation with instructions to [download and install][], update and uninstall the app from F-Droid. * Tor Browser has dropped support for [legacy operating systems]. We updated the documentation to reflect this update. [Tor daemon failing in the background]: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42714 [download and install]: https://support.torproject.org/tor-vpn/getting-started/download-and-install/ [legacy operating system]: https://support.torproject.org/tor-browser/security/legacy-os/ ## Farsi-speaking user support * 33 tickets in total (↓75 as compared to February) * 7 tickets on Email * 26 tickets on Telegram * In March, users in Iran have been experiencing a near-total shutdown. As per reports, only a handful number of whitelisted services remain accessible and most common censorship circumvention tools are no longer working reliably. For users who managed to reach out to us on our support channels, we have been suggesting [dnstt][] (DNS tunneling) with Tor. Information about it is being shared through the [@GetDnsttBot on Telegram][], along with instructions on how to use dnstt with Orbot and Tor Browser. * As per a [survey] conducted via Telegram in Farsi for internet users in Iran, with about 13,400 responses, 12% of the respondents mentioned they were able to access the internet using dnstt. [dnstt]: https://dnstt.network/ [@GetdnsttBot on Telegram]: https://t.me/getdnsttbot [survey]: https://gitlab.torproject.org/tpo/anti-censorship/censorship-analysis/-/iss… ## Russian-speaking user support * 709 tickets in total (↓179 as compared to February) * 176 tickets on Email (↑19) * 518 tickets on Telegram (↓207) * 7 tickets on WhatsApp (↑1) * 8 tickets on Signal (↑8) * As a result of Russia blocking Telegram since the mid of March, the number of tickets we received over our user support channel on Telegram has dropped significantly.

It is ineffective because it is easily circumvented by users and fails to remove targeted content, which simply reappears under new domain names. It is harmful because this blunt instrument cannot distinguish between lawful and unlawful material, leading to overblocking, fragmentation of the Internet’s global naming system, and the failure of interconnected services, including critical security protocols. Finally, it is impractical because the DNS is not bound by geography, meaning national blocking orders against global resolvers create unintended and widespread extraterritorial effects. Mandated blocking is the wrong tool for a role the DNS was never designed to play." == Reading group == * We will discuss "" on * * Questions to ask and goals to have: * What aspects of the paper are questionable? * Are there immediate actions we can take based on this work? * Are there long-term actions we can take based on this work? * * Is there future work that we want to call out in hopes that others will pick it up? * Next in the Reading Group Queue: * == Updates == Name: This week: - What you worked on this week.
