Interview with Tor Summer of Privacy Student Donncha O'Cearbhaill

Donncha O'Cearbhaill is one of Tor's new Summer of Privacy students. We asked him about his plans for the summer.

1. Why are you interested in working on Free software?

I'm delighted to be able to contribute back to the Free software community which has provided me with so many of the tools and systems I use daily. It's reassuring to know that any software that I write for the Tor Project will always be available for people to use, modify, and redistribute.

2. Describe your project to a lay reader--How will it work, and who will it help?

Most large web services distribute the requests to their sites across multiple servers so as to better handle the load from their users. However, at present, Tor onion (hidden) services are limited to routing all their traffic via Tor running on a single server. This is becoming a bottleneck for popular hidden services and is causing difficulty in growing to more users.

My project aims to implement a tool that will allow onion service operators to distribute connections to their services across multiple back-end servers. For users, I hope this will allow their favourite services to become faster and more reliable.

As a bonus, the project should allow operators to further increase the security of the services by allowing private keys to be stored away from the computer hosting their actual onion service / website.

3. What do you hope to get out of the Tor Summer of Privacy?

I've really enjoyed my interactions with the Tor community over the past few months. Over the summer, I hope to provide something of value and give back to the community. As I don't have a formal computer science background, I'm also looking forward to working with my mentors to improve the standard of my software design and development and generally gain more experience.

4. Who are your heroes--if you have any--in internet freedom software?

The work of many people in the Internet freedom community inspires me. I'm particular grateful to people such as Edward Snowden, Julian Assange, and Jeremy Hammond who have made massive sacrifices to try to bring light to the expanding surveillance state.

I'm inspired by the free software developers and advocates everywhere who continue trying to doing something about it.

5. Where do you go to school and what are you studying?

I'm just finishing my degree in Medicinal Chemistry in Trinity College, Dublin, Ireland. My exams run over the next few weeks and after that I'm looking forward to hacking on some code rather than molecules.

6. Anything else you'd like to say?

I'd like to thank the Tor Project for accepting me into Summer of Privacy program, and thank all in the Tor community for being so welcoming to me so far.

Roger Dingledine Becomes Interim Executive Director of the Tor Project

Tor Project co-founder Roger Dingledine has been appointed Interim Executive Director of the organization by Tor's Board of Directors. He replaces Andrew Lewman, who is leaving the Tor Project to take a position at an Internet services company. Roger will continue in this role until a permanent replacement has been found. During this period, Tor Project co-founder Nick Mathewson will take on the role of Interim Deputy Executive Director.

Tor Weekly News — April 29th, 2015

Welcome to the seventeenth issue in 2015 of Tor Weekly News, the weekly newsletter that covers what’s happening in the Tor community.

Tor Browser 4.5 is out

Mike Perry announced the first stable release in Tor Browser’s 4.5 series. This version includes numerous major new features and updates, and represents a significant advance in user-friendly security technology.

The most visible new features have been covered in previous issues of Tor Weekly News. Tor Browser’s onion menu has been reorganized for ease of use, and now includes a diagram showing the locations and IP addresses of the relays that make up the Tor circuit used to access a website — one of the features most missed from the now-defunct Vidalia controller. The “security slider”, accessible in the onion menu’s “Privacy and Security Settings”, can be set at one of four levels depending on a user’s needs, disabling browser features which may give adversaries an opportunity to attack, at the cost of making some web pages less usable.

Tor Browser’s “first-party isolation” feature has been expanded: when you visit a website, all requests for the content on that domain name (including third-party elements like advertising beacons, analytics trackers, and content delivery networks) will be made over the same Tor circuit, and each domain name is restricted to its own Tor circuit, which is maintained for as long as the site is in active use. This makes an adversary’s tracking of a Tor user’s activity across different sites even harder than it was already, while ensuring that the usability of websites is not affected by sudden changes of exit relay.

For full explanations of these and other features — including better desktop integration, a new search provider, improvements to the software signature process, and more — please see the team’s announcement. Users of what was the 4.5-alpha series will be prompted to update automatically by their Tor Browser, while users of the stable 4.0.8 will receive the same prompt in about a week’s time, “because [the] changes are significant”. And if you don’t already have a working copy of Tor Browser, head to the download page to get started. Congratulations to the Tor Browser team on reaching this milestone!

Miscellaneous news

Karsten Loesing announced that the onionoo-announce mailing list will be shut down in favor of posting announcements about major Onionoo protocol updates to the tor-dev mailing list, “because each Tor mailing list makes it more difficult for new contributors to decide which of them to subscribe to”. If these announcements are relevant to your work, please be sure to subscribe to tor-dev — you can set your mail client to filter for the keyword “Onionoo” if you’d rather not receive other Tor development-related messages.

Also in Onionoo news, Thomas White announced that his mirror of the service is now also available at an onion address.

Lucas Erlacher announced version 0.3.0 of OnionPy, “a pure-python Onionoo request wrapper that supports transparent caching”. The new release respects Onionoo’s “version” field in query responses.

Tor Browser 4.5 is released

The Tor Browser Team is proud to announce the first stable release in the 4.5 series. This release is available from the Tor Browser Project page and also from our distribution directory.

The 4.5 series provides significant usability, security, and privacy enhancements over the 4.0 series. Because these changes are significant, we will be delaying the automatic update of 4.0 users to the 4.5 series for one week.

Usability Improvements


On the usability front, we've improved the application launch experience for both Windows and Linux users. During install, Windows users are now given the choice to add Tor Browser to the Start Menu/Applications view, which should make it easier to find and launch. This choice is on by default, but can be disabled, and only affects the creation of shortcuts - the actual Tor Browser is still self-contained as a portable app folder. On the Linux side, users now start Tor Browser through a new wrapper that enables launching from the File Manager, the Desktop, or the Applications menu. The same wrapper can also be used from the command line.

We've also simplified the Tor menu (the green onion) and the associated configuration windows. The menu now provides information about the current Tor Circuit in use for a page, and also provides an option to request a new Tor Circuit for a site. Tor Browser is also much better at handling Tor Circuits in general: while a site remains in active use, all associated requests will continue to be performed over the same Tor Circuit. This means that sites should no longer suddenly change languages, behaviors, or log you out while you are using them.

Security Improvements


On the security front, the most exciting news is the new Security Slider. The Security Slider provides user-friendly vulnerability surface reduction - as the security level is increased, browser features that were shown to have a high historical vulnerability count in the iSec Partners hardening study are progressively disabled. This feature is available from the Tor onion menu's "Privacy and Security Settings" choice.


Figure 2: The new Security Slider


Our Windows packages are now signed with a hardware signing token graciously donated by DigiCert. This means that Windows users should no longer be prompted about Tor Browser coming from an unknown source. Additionally, our automatic updates are now individually signed with an offline signing key. In both cases, these signatures can be reproducibly removed, so that builders can continue to verify that the packages they produce match the official build binaries.

The 4.5 series also features a rewrite of the obfs2, obfs3, and ScrambleSuit transports in GoLang, as well as the introduction of the new obfs4 transport. The obfs4 transport provides additional DPI and probing resistance features which prevent automated scanning for Tor bridges. As long as they are not discovered via other mechanisms, fresh obfs4 bridge addresses will work in China today. Additionally, barring new attacks, private obfs4 addresses should continue to work indefinitely.


Privacy Improvements


On the privacy front, the 4.5 series improves on our pre-existing first party isolation implementation to prevent third party tracking. First party isolation provides the property that third party advertisements, like buttons, and "mashup" content that is included on one site will only know about your activity on that site, and will not be able to match it to your activity while you are on any other site. In other words, with first party isolation, Facebook, Twitter, and Google+ can't track you around the entire web using their infamous like buttons.

Specifically, in the 4.5 release, we now ensure that blob: URIs are scoped to the URL bar domain that created them, and the SharedWorker API has been disabled to prevent cross-site and third party communication. We also now make full use of Tor's circuit isolation to ensure that all requests for any third party content included by a site travel down the same Tor Circuit. This isolation also ensures that requests to the same third party site actually use separate Tor Circuits when the URL bar domain is different. This request isolation is enforced even when long-lived "HTTP Keep-Alive" connections are used.

We have also improved our resolution and locale fingerprinting defenses, and we now disable the device sensor and video statistics APIs.

New Search Provider


Our default search provider has also been changed to Disconnect. Disconnect provides private Google search results to Tor users without Captchas or bans.

Tor Weekly News — April 22nd, 2015

Welcome to the sixteenth issue in 2015 of Tor Weekly News, the weekly newsletter that covers what’s happening in the Tor community.

A new era at the Tor Project

Andrew Lewman, who has overseen the Tor Project’s business operations since 2009 as Executive Director, will shortly be moving on to a new position at the head of an internet services company. During Andrew’s time as Executive Director, Tor has developed into a leading privacy tool used every day by millions of users around the world, and the Tor community has grown to include more engineers, researchers, activists, and volunteers than ever before. Thanks to Andrew for everything he has done for the Tor community, and best of luck for the future!

Tor Summer of Privacy — chosen projects announced!

The application period for the first-ever Tor Summer of Privacy — the funded development season inspired by Google Summer of Code — closed last week, with twenty-two proposals submitted before the deadline. All the project ideas were of a very high standard, but sadly funding and mentoring constraints meant that only four could be chosen, and Damian Johnson took to the Tor blog to share the list of the winners.

Donncha O’Cearbhaill will be implementing a system to increase the availability of large onion services by balancing requests across several back-end servers, each running its own Tor instance; Jesse Victors will be working on a project entitled “The Onion Name System: Tor-Powered Distributed DNS for Tor Hidden Services”, based on his thesis; former GSoC student and GetTor project leader Israel Leiva will be returning to carry out further work on the alternative distribution system for Tor software; and Israel’s twin brother Cristóbal will be developing a web-based status dashboard for Tor relays.

These are all exciting and important projects, and as Damian wrote, “we’re thrilled to have them with us”. Even if you submitted a proposal that wasn’t chosen, please don’t be discouraged: a number of the projects rejected for lack of resources are still high on Tor developers’ wishlists, so if you can find any way to contribute in the future, feel free to seek advice and assistance from the community.

Coding for Tor Summer of Privacy officially starts on May 25th. In the meantime, congratulations to the four students!

Miscellaneous news

Yawning Angel announced obfs4proxy-0.0.5. This release is better able to detect whether the parent Tor process has crashed, and also brings IPv6 support to clients. All users are recommended to upgrade: please see Yawning’s announcement for further details.

Anthony G. Basile announced version 20150411 of Tor-ramdisk, the micro Linux distribution whose only purpose is to host a Tor server in an environment that maximizes security and privacy. This release includes updated versions of Tor and the Linux kernel.

David Fifield wondered about the cause of a sudden large increase in the number of Tor clients using the meek pluggable transport that occurred around April 15th.


This issue of Tor Weekly News has been assembled by Harmony.

Tor Summer of Privacy Projects

in

We're pleased to announce the projects for this year's Tor Summer of Privacy! Of our twenty-two applicants sadly we only had funding for four, so without further ado here they are!
 

Projects officially begin on May 25th. We're thrilled to have them with us, and have our fingers crossed that they'll stay afterward to become core developers!

Tor Weekly News — April 15th, 2015

Welcome to the fifteenth issue in 2015 of Tor Weekly News, the weekly newsletter that covers what’s happening in the Tor community.

Tor Browser 4.0.8 is out

Mike Perry announced a new stable release by the Tor Browser team. This version is exactly the same as 4.0.7, which was briefly advertised to users last week but then withdrawn because a bug would have caused it to endlessly recommend updating.

This release includes Tor 0.2.5.12, which fixes the recent onion service and client crash bugs.

There is no corresponding Tor Browser alpha update; that series will become the new stable release in a couple of weeks.

Download your copy of Tor Browser 4.0.8 from the project page, or over the in-browser update system.

Hidden services that aren’t hidden

As the name implies, Tor hidden services (also known as “onion services”) are location-hidden and anonymous, just like regular Tor clients. There may be instances, however, in which a potential hidden service operator doesn’t much care about being hidden: they are more interested in the other unique properties of hidden services, like free end-to-end encryption and authentication, or they want to prevent their users from accidentally sending information non-anonymously. For example, even though everyone knows who Facebook are and where to find them, their users still have things to gain from using their .onion address.

At the moment, these kinds of services are still forced to use the regular hidden service protocol, meaning they connect to rendezvous points over a Tor circuit. Hiding someone who doesn’t want to be hidden is an inefficient use of network resources, and needlessly slows down connections to the service in question, so Tor developers have been discussing the possibility of enabling “direct onion services”, which sacrifice anonymity for improved performance.

George Kadianakis requested feedback on a draft of a Tor proposal for this feature. One of the major questions still to be resolved is how to ensure that nobody enables this option by mistake, or fails to understand the implications for their service’s anonymity. Possible solutions include choosing a better name, making the configuration file option sound more ominous, or even requiring the operator to compile Tor themselves with a special flag.

See George’s proposal for more use-cases and full details of the concept, and feel free to comment on the tor-dev list thread.

Tor Summer of Privacy — entry closing soon!

If you’d like to participate in the first-ever Tor Summer of Privacy, you still have the chance — but be quick, as the application period closes on Friday.

Competition for places is already strong, so make it as easy as possible for your entry to be chosen: look at previous applications for an idea of what Tor developers like to see, drum up interest from potential mentors on the tor-dev mailing list or IRC channel, link to your best code samples, and show the community that you can take the initiative in moving your project forward. Good luck!

More monthly status reports for March 2015

A few more Tor developers submitted monthly reports for March: Isis Lovecruft (for work on BridgeDB and pluggable transports), Arlo Breault (reporting on Tor Messenger and Tor Check), Karsten Loesing (for projects including hidden service statistics, translation coordination, and Tor network tools), and Colin C. (for work on support, documentation, and localization).

The Tails team published its March report. Take a look for updates on development, funding, and outreach; summaries of ongoing discussions; Tails in the media; and much more besides.

Miscellaneous news

Nathan Freitas announced the third release candidate for Orbot v15. This version supports the x86 processor architecture, so devices such as the Galaxy Tab 3 and the Asus Zenphone/Padphone are now officially Tor-compatible. See Nathan’s announcement for the full changelog.

Giovanni Pellerano announced GlobalLeaks 2.60.65, featuring lots of bugfixes, improved localization (including eight new languages), and more.

David Fifield located and fixed a problem with meek’s Microsoft Azure backend that was causing it to run much more slowly than the other two options. “If you tried meek-azure before, but it was too slow, give it another try!”

Thanks to John Penner for running a mirror of the Tor Project’s website and software!

A New Era at the Tor Project

Andrew Lewman, our current Executive Director, is leaving The Tor Project to take a position at an Internet services company. While at Tor, Andrew was passionate about using our tools to help people from diverse backgrounds and points of view benefit from online privacy. We thank Andrew for his contributions and wish him well.

The Board has asked Tor’s Executive Committee to plan the transition. As a member of this committee, I can say that I expect that Tor Project co-founder Roger Dingledine will serve as interim Executive Director while we conduct the search for a permanent replacement.

Although we are sad to see Andrew leave, Tor is entering an exciting period of growth. We are exploring the establishment of Tor Labs and launching new programs like our Tor Summer of Privacy.

Our developers are building the next generation of Internet anonymity tools — and we continue to lead the international discussion on Internet freedom and liberty through our public talks and research.

Thanks to the entire Tor community for your help as we move forward!

--Wendy Seltzer
Member of the Board of Directors of the Tor Project
