Tails 5.20

Cambios y actualizaciones

  • Update Tor Browser to 13.0.4.

  • Update Thunderbird to 115.5.0.

  • Stop downloading the AdGuard filter list for uBlock Origin in the language of the session.

    This prevents some advanced browser fingerprinting. (#20022)

Fixed problems

Since many of you are still reporting issues with the new Persistent Storage, we are releasing several improvements to the Persistent Storage and the WhisperBack error reporting tool:

  • Fix an error when activating the Persistent Storage. (#20011)

  • Fix the translation of the WhisperBack interface. (#20040)

  • Improve the interface of WhisperBack to make it easier to report the information we need to troubleshoot issues. (#19351)

For more details, read our changelog.

Tails 5.19.1

This release is an emergency release to fix an important security vulnerability in Tor.

Cambios y actualizaciones

  • Update the Tor client to 0.4.8.9, which fixes the TROVE-2023-006 vulnerability.

    The details of TROVE-2023-006 haven't been disclosed by the Tor Project to leave time for users to upgrade before revealing more. We only know that the Tor Project describes TROVE-2023-006 as a "remote triggerable assert on onion services".

    Our team thinks that this vulnerability could affect Tails users who are creating onion services from their Tails, for example when sharing files or publishing a website using OnionShare.

    This vulnerability might allow an attacker who already knows your OnionShare address to make your Tor client crash. A powerful attacker might be able to further exploit this crash to reveal your IP address.

    This analysis is only a hypothesis because our team doesn't have access to more details about this vulnerability. Still, we are releasing this emergency release as a precaution.

    OnionShare is the only application included in Tails that creates onion services. You are not affected by this vulnerability if you don't use OnionShare in Tails and only use Tails to connect to onion services and don't create onion services using Additional Software.

    More details about TROVE-2023-006 will be available on the Tor issue #40883 sometime after the release.

Auditoría de seguridad de la integración del Almacenamiento Persistente y Tor

In March 2023, Radically Open Security conducted a security audit on the major improvements that we released in Tails 5.8 (December 2022) on the Persistent Storage, the Unsafe Browser, and the Wayland integration.

To better protect our users, we addressed most of the security vulnerabilities as soon as they were discovered and reported to us, without waiting for the audit to be complete and public. We can now share with your the final report.

We are proud of the conclusion of the auditors:

Overall, the Tails operating system left a solid impression and addressed most of the concerns of an average user in need of anonymity.

This is particularly evident in the isolation of various components by the developers. For example, the configured AppArmor rules often prevented a significant impact of the found vulnerabilities. Shifting to Wayland was a good decision, as it provides more security by isolating individual GUI applications.

All in all, no serious vulnerabilities were found through the integration into Wayland. Unsafe Browser and Persistent Storage should now be less vulnerable to attack, as all vulnerabilities have been fixed.

The auditors found 6 High, 1 Moderate, 3 Low-severity issues. Another issue was fixed before the actual impact was assessed and so marked as having Unknown severity.

We fixed all these issues as soon as possible and before making them public on our GitLab. The last issue was fixed in 5.14, 3 weeks after it was reported to us.

As good as the results of this audit are, they also serve as a reminder that no software is ever 100% secure and that every release of Tails can fix critical security vulnerabilities. Your best protection against all kinds of attack is to keep your Tails up-to-date.

Because at Tails we believe that transparency is key to building trust, all the code of our software is public and the results of this audit as well. You can find below a summary of all the issues and their fixes.

Tails report for October 2023

Highlights

  • In early October, we got together in Rome for a hybrid sprint! We reflected on the year so far, our financial health, and plans to make Tails' mission more sustainable.

  • Our annual fundraiser is live! For this year's fundraiser, we are reflecting on a year in which progressive, liberatory movements battled intense online surveillance from powerful public and private actors alike.

As we enter 2024, make the gift of privacy. We welcome each contribution, no matter the size. And there are many ways to contribute). Spread word!

And while we have you here, consider nominating Tails for support through Proton's fundraiser. Nominations close on 13 November 2023!

  • We also have a new sponsor. Please welcome James Seibel to the community!

Releases

Tails 5.18 was released on October 03, 2023, and Tails 5.19 was released on October 31, 2023.

  • You have upgrades to Tor Browser, Thunderbird, and the Linux kernel.

  • You can now close a given Tor circuit from the Onion Circuits interface.

  • Using SecureDrop on airgapped machines running Tails is even more secure now. Tails 5.19 improves the cryptographic parameters of PGP keys stored in these airgapped machines. SecureDrop is widely used by investigative journalists and whistleblowers.

Metrics

Tails was started more than 830,216 times this month. That's a daily average of over 26,780 boots.

Tails 5.19

Nuevas características

Closing a Tor circuit from Onion Circuits

You can now close a given Tor circuit from the Onion Circuits interface. This can help replace a particularly slow Tor circuit or troubleshoot issues on the Tor network.

To close a Tor circuit:

  1. Connect to the Tor network.

  2. Choose Tor status menu ▸ Open Onion Circuits in the top navigation bar.

  3. Right-click (on Mac, click with two fingers) on the circuit that you want to close.

  4. Choose Close this circuit in the shortcut menu.

    When you close a circuit that is being used by an application, your application gets disconnected from this destination service.

    For example, when you close a circuit while Tor Browser is downloading a file, the download fails.

  5. If you connect to the same destination server again, Tor uses a different circuit to replace the circuit that you closed.

    For example, if you download the same file again, Tor uses a new circuit.

Addition of sq-keyring-linter

At the request of people who use SecureDrop to provide secure whistleblowing platforms across the world, we added the sq-keyring-linter package. sq-keyring-linter improves the cryptographic parameters of PGP keys stored in their airgapped machines.

Cambios y actualizaciones

  • Update Tor Browser to 13.0.1.

  • Update the Tor client to 0.4.8.7.

  • Update Thunderbird to 115.4.1.

  • Update the Linux kernel to 6.1.55.

Tails report for September 2023

Highlights

  • From Tails 5.14, we started asking Tails users to consider donating to Tails when they open Electrum. Since then, Electrum users on Tails have donated USD 5k towards Tails' mission. We are so grateful for your generous support!

  • The Tails community had very meaningful and lovely contributions to the project. McFly helped solve an issue some users had while identifying the 'Alt' key on Apple keyboards, and also designed some slick business cards. And jawlensky submitted a huge branch with tons of changes all over the website. It will take us a few weeks to process it all!

  • We were in Kerala at DebConf 2023. Thank you to DebConf for sponsoring our participation.

¡Regala privacidad!

Ante la creciente sofisticación y magnitud de las intrusiones de agentes maliciosos en los derechos humanos, Tails ofrece esperanza a quienes buscan refugio en un entorno digital más seguro. Nos encontramos en el precipicio de un futuro en el que la privacidad digital debería ser un derecho fundamental, no un lujo.

Desde que empezamos en 2008, millones de personas de todo el mundo han utilizado Tails para ser más autónomas, seguras y anónimas en su vida digital.

Hemos llegado tan lejos gracias a ti, y necesitamos tu apoyo para seguir haciendo lo que mejor sabemos hacer: ¡ofrecer el sistema operativo que más protege la privacidad del mundo!

Vuestras donaciones representan la mayor parte de nuestros ingresos. Pero esta parte se ha reducido en los dos últimos años. Las donaciones filantrópicas han disminuido en todo el mundo, un síntoma más de las difíciles condiciones políticas y económicas en las que nos encontramos. Pero esto no ha moderado nuestras ambiciones. A pesar de estos retos, Tails ha crecido y mejorado en el último año. Este año hemos dedicado más tiempo a mejorar Tails que en cualquier otro año anterior. Pero para lograrlo, hemos dependido un poco más del apoyo de grandes donantes institucionales.

Aunque agradecemos el apoyo y la generosidad de nuestros "grandes" donantes, queremos reducir al mínimo nuestra dependencia en ellos. Apostamos por tener fuentes de ingresos diversificadas como nuestro seguro frente a la volatilidad económica y la garantía de hacer crecer Tails de forma sostenible y con total autonomía de decisión. Aunque esto significa que dependemos aún más de vosotros. ¡Y de ahí esta recaudación de fondos!

Nuestro objetivo es claro: hacer que Tails sea aún más útil para las personas vulnerables en entornos de alto riesgo. Y queremos hacerlo siendo tan autónomos como nuestros usuarios.

Los ingresos de esta recaudación de fondos impulsarán iniciativas que harán que Tails sea aún más usable y seguro. Queremos añadir nuevas y grandes características a Tails, mejorar la experiencia del usuario con aún más pruebas de usabilidad, y aumentar el uso de Tails en más geografías de todo el mundo.

Cada donación, por pequeña que sea, marca la diferencia. Haz tu donativo hoy y ayúdanos a mantener a Tails con vida en 2024 y más allá. Aquí tienes 5 formas de participar:

  1. Haciendo una donación periódica. Donaciones periódicas son el mejor seguro para la misión de Tails. Nos ayudan a superar las incertidumbres económicas y a planificar nuestro trabajo de forma sostenible.

  2. With a one-time gift. If you can't set-up a recurring donation, you can make a one-time donation. Donate via PayPal, bank transfers, mail in your checks, or just send us good, old cash. Here's a pro-tip: donations of over $1 000 entitle you to some neat sponsorship benefits.

  3. A través de criptomonedas. Aceptamos donaciones de criptomonedas en Bitcoin, Ethereum y Monero.

  4. Compensación de donaciones. Si tu empresa tiene programas de compensación de donaciones, considera la posibilidad de buscar Riseup Labs y donar a Tails a través de Riseup Labs. Riseup Labs es nuestro patrocinador fiscal en los Estados Unidos de América.

  5. Corre la voz. Y, por último, por favor, comparte esta recaudación de fondos con tu red de contactos, amigos y colegas. Ayúdanos a ampliar nuestro impacto llegando a un público más amplio.

Thank you for being part of this journey and a toast to our future adventures together! Oh, and in case you have somehow managed to skip over all the links to our donations page so far, here it is: https://tails.net/donate/.

Tails report for August 2023

Tails report for August 2023

Highlights

  • We are hiring! We are looking for a Linux generalist to join the Foundations team. We are committed to making the project more diverse, and request your help circulating the opening.

  • We published our recommendations for hardware to run Tails.

  • We interviewed journalists, activists, and digital security trainers to better understand their communication needs. We want to speak to more such folks, especially if they are working in African and Asian contexts. If you are reading this, or know of anyone who fits, sajolida would love to hear from you. He's at sajolida@pimienta.org.

  • And internally too, we are working on better communication and collaboration tools. We are trying to make working on Tails a bit friendlier for those who don't suffer from command line addiction.

Releases

Tails 5.16 was released on August 06 2023.

  • You have shiny, upgraded versions of Tor Browser and Thunderbird.

  • Some users were experiencing difficulties while unlocking Persistent Storage. In Tails 5.16, we fixed some of these issues and continued working on it for Tails 5.17.

  • You will now see the passphrase recommendation for the Persistent Storage only in lower case. Capitalising each word makes for more cumbersome typing, and is not more secure.

Tails 5.16.1 was released on August 15 2023. It fixes a critical vulnerability in the Linux kernel that large, powerful actors could have exploited (but, to the best of our knowledge, haven't).

Metrics

Tails was started more than 761771 times this month. That's a daily average of 24,573 boots.
