How the FSF Sysadmins are Blocking Botnets with reaction

For nearly two years the Free Software Foundation has been fighting web crawlers (including many aggressively scraping training data for AI models). A botnet controlling about five million IPs hit one system for six months in 2025. Their systems administrator wrote this week that they view these as distributed denial-of-service attacks. How are they fighting back? We noticed patterns in the scrapers that were abnormal, which gave us material for writing regular expressions. Searching for the regular expression then gave us a large lists of IP addresses. Looking up the origin of those IP addresses revealed that some of the crawlers were using botnets of residential IP addresses to scrape faster and avoid detection. We looked for what kinds of botnets might be generating the kind of traffic that we were seeing, and one that we suspected was called the "Vo1d" botnet, comprised of smart TVs running some sort of compromised app... We got confirmation that at least some of the botnet traffic hitting GNU Savannah was originating through the Vo1d/Popa botnet. We placed our regular expressions in fail2ban, and found that we were hitting the maximum rules that could be added to UFW firewall rules on our systems which showed degradation around 65,000 rules... We learned about ipset and configured fail2ban to add IP addresses that it found to IP sets. Using ipset, we kept building larger IP sets and did not find instability with as large as five million rules... We eventually found a promising project on Framasoft's forge Framagit called reaction written by ppom... After we ran into scaling issues with our initial implementation, we developed a much faster implementation where the reaction shutdown process would export the IP sets to disk and the reaction startup process would restore the IP sets. This allowed us to have nearly instantaneous restarts of the service to apply new rules. We published both of our configurations upstream to reaction's wiki so that everyone can benefit from it. reaction's getting started documentation now leads to the method that we proposed... Many sysadmins know about fail2ban, but not enough people know about reaction. I am very grateful to ppom for the help they have provided and for the tremendous project they have released to the world with reaction. We have implemented other defenses as well, but reaction is doing the majority of the automated work keeping our sites online.

FSF Shares Update on 'LibrePhone' and New Automated Site Monitoring Tool

At the end of 2025, the FSF launched LibrePhone project, which is working to "better understand and reverse-engineer the nonfree blobs used by a great majority of (if not all) system on a chip designs available today." The FSF's summer newsletter shares this update: We started with researching the proprietary files in Android phones supported by the Lineage project, an Android-based volunteer-led mobile phone operating system with much free software already in it. Our current, primary focus is on the radio blobs that control WiFi, Bluetooth, NFC, and cellular communications. The software freedom issues with mobile computing have been around for a long time, with the most challenging issue being the baseband/modem firmware that relies heavily on proprietary software. This creates a technical and legal maze that is nearly impossible to break free from, but that doesn't mean we should ever stop working to create free systems. It certainly doesn't mean we shouldn't liberate the software that we know can be free software. Now, half a year into this project, lead developer Rob Savoye has extracted firmware from over 200 Lineage install packages, processed 85GB of files, and imported the results of these analyses into a PostgreSQL database for cross-device comparison... [M]uch of the software and blobs we need to work through are shared across multiple devices; this means even greater strides for mobile phone freedom... As insurmountable as it may seem at times, every blob we manage to free up will be progress. The FSF has proven time and time again that it can bring the free software philosophy to life, not just by advocating for it, but by making it so. The bulletin also describes how waves of botnets from "aggressive LLM scrapers, vulnerability scanners, poorly optimized CI/CD servers" inspired the FSF to create a new free-as-in-freedom automated monitoring tool: In our efforts to combat the botnets, we optimized several detection rules to ban abusive behavior. We found the upper limit of fail2ban and replaced it with reaction, an efficient alternative with our configuration that uses ipset. We also split several monolithic machines into many separate machines so that when a web service is overwhelmed the other functions of the service do not go down with it... We found quite a few ways to respond to and prevent botnet attacks, but still faced a significant related challenge: communicating when a website or service is down... Uptime Kuma is a human-readable, automated monitoring addition to our systems... You can check out our recently-launched self-hosted Uptime Kuma instance at https://status.fsf.org/. When you see the page, you will also likely say, "Wow! The FSF and GNU sure do run a ton of services!" and you would be right... If you maintain websites and services, and are looking for a simple way to communicate publicly with your users, consider using Uptime Kuma or another free software solution instead of choosing a proprietary monitoring solution." There's also an article on the state of free-as-in-freedom videogame console emulators.

FSF 'LibreLocal' Organized From Prison by Iranian Man Jailed for 'Cyber-Crimes' After Promoting Free Software

Thursday the Free Software Foundation blogged about this year's 47 'LibreLocal 2026' meetups, highlighting 10 that took place in Australia, Mexico, the United States, New Zealand, Cameroon, Switzerland, Spain, Argentina, China, and Iran. "Far from each other in many parts of the world, they came together around one unifying belief: free software." We envisioned LibreLocal as a collage of in-person community meetups that would bring people together to swap ideas, learn from each other, and celebrate free software. When we asked the free software community to organize LibreLocals last year, the response was very inspirational: 29 different meetups were hosted. After we made the global call this year, we were greeted with an even more enthusiastic response... Organizers hosted LibreLocals in cafes, bars, restaurants, libraries, universities, a computer repair shop, and even as part of a field trip to the System Source Museum, a museum dedicated to the history of computing in Hunt Valley, Maryland, USA. We also learned that a LibreLocal was organized inside Vakil Abad Prison in Mashhad, Iran by a free software supporter. Originally planned to be held in Shiraz, we were informed of this change in location on the LibreLocal wiki page set up for listing all LibreLocals. The updated entry, by another free software supporter in Iran, reads: "This year, one of our dedicated activists organized a LibrePlanet event from within prison in Iran. Currently serving a sentence for "cyber-crimes" related to his promotion of free software, he continues to introduce the principles of software freedom to his fellow inmates. We have placed this banner to honor his resilience and the community of individuals in prison who continue to stand for technological freedom. His identity will be revealed when it is safe to do so." Advocating for user freedom should never result in a prison sentence. We especially admire and respect the bravery and strength of those who fight for software freedom in the most dangerous and oppressive of environments. 50 people attended the LibreLocal meetup in Switzerland, according to one of the organizers, "forging connections between several local free software stakeholders and strengthening their cohesion." But the FSF's blog post stresses these are "ten stories among many more of free software supporters from across the globe... We also thank you our donors and associate members for the support that makes such meetups possible." The GNU Press Shop is now open through July 19 for their biannual fundraiser, offering a variety of freedom-respecting novelties including an FSF-branded antisurveillance webcam guard and both technical and philosophical books, like Richard Stallman's Free as in Freedom (which allegedly has turned up in Anthropic's training data). Other items include a slick new FSF logo sticker, a brass and zinc GNU "emblem" pin with real gold plating, and a cheeky sticker reminding everyone that "There is no cloud." And there's even a plush GNU toy.

Sortie de Trisquel GNU/Linux 12 « Ecne »

La distribution Trisquel GNU/Linux est sortie en version 12 dite « Ecne ». Elle est basée sur Ubuntu et plus précisément sa version 24.04 dite « Noble Numbat » qui est la précédente version maintenue à long terme (Long-Term Support, ou LTS pour les intimes). Mais il y a encore un support de 3 ans (jusqu'en mai 2029) par Canonical (la société derrière Ubuntu), donc ce n'est pas grave, et ça s'explique sans doute par le peu de force de la distribution.

Mais de toute façon, quel est l'intérêt de cette énième distribution GNU/Linux ? C'est rien de moins qu'une des rares qui est 100% libre et donc approuvée par la FSF (Free Software Foundation) sur la base des GNU FSDG (Free System Distribution Guidelines), contrairement par exemple à Debian qui n'en était historiquement pas loin et a récemment régressé. Avec Trisquel, il n'y a donc notamment pas de blob privateur dans le noyau Linux (car oui, de base il en contient) et pas d'incitation à installer du logiciel privateur.

De plus, Trisquel se veut respectueux de la vie privée. On peut constater ça avec le cas des navigateurs web. Firefox n'est pas proposé au profit de Abrowser qui en est une version dérivée (fork) avec quelques améliorations. De plus, GNU IceCat est proposé et va lui plus loin. Enfin, si on veut un autre moteur web majeur, il y a ungoogled-chromium, en plus bien sûr des navigateurs web basés sur WebKit (comme GNOME Web).

Si la souveraineté ordinatique vous intéresse (il parait que c'est devenu à la mode, dans les discours du moins…), Trisquel GNU/Linux est assurément un bon choix si vous vous fichez d'avoir les dernières versions des logiciels. Toutefois il y a aussi GNU Guix si ça vous dérange.

Pour l'anecdote, un VIP du logiciel libre utilise Trisquel. Et oui, rien de moins que Richard Stallman !

FSF Patches Two-Year-Old Vulnerability Found by AI Researchers in GNU Savannah Repository

The Free Software Foundation's GNU Savannah hosts thousands of free software projects — both GNU and non-GNU projects, including Drupal. But in early May, security researchers from Hacktron.AI reported vulnerabilities and demonstrated an exploit, according to a new statement Friday from the FSF: We have been working with these researchers since their initial report, and have also addressed additional security issues they submitted. All reported issues have been patched thanks to the hard work of GNU and FSF volunteers, as well as FSF staff. After thorough review, we have found no reason to believe that sensitive project data or credentials were accessed, nor that there has been any compromise of Savannah's software supply chain. Nevertheless, we take the security of the GNU system, the tools which make it possible, and the projects we host very seriously. This body of software has become essential to millions (if not billions) of users around the world. We are therefore taking additional precautionary steps. Though the initial security issue was reported to us in early May, the vulnerabilities were discovered in software that was published approximately two years prior. We will be communicating directly with Savannah-hosted projects about steps they can take to review and strengthen the security of their projects. We have also communicated with the other Savane instances we're aware of to assist their review of their own environments, and take any steps needed to help protect their users... This statement is intended as an initial notice. We expect to publish a report on the incident within 30 days. Hacktron.AI bills itself as "Your AI teammate for security." Its web page notes that its investors include Meta, DeepMind, and Perplexity.

Free Software Foundation's Call for 'LibreLocals' Answered on Six Continents - With More Coming

The Free Software Foundation announced this week that "its global call for free software supporters to organize LibreLocals this May resulted in free software supporters organizing forty-six LibreLocal events on six continents thus far." (And new dates and locations are being added daily.) The FSF invited free software supporters to organize in-person community meetups in their area during May 2026, or LibreLocal month, to bring people together to swap ideas, learn from each other, and celebrate free software. People were encouraged to organize events grounded in freedom to help spread the free software philosophy.... "The success of these LibreLocals speaks to how many people globally are interested in free software and ready to build community, and it demonstrates the strength of our movement" [said FSF executive director Zoë Kooyman]. "People getting together like this also proves how computer freedom and digital rights are on people's minds. When we reject freedom-restricting software and promote software that respects user rights, it helps further so many other basic rights...." The FSF has financially supported some of the events, but notes organizers are going above and beyond to create noteworthy events by any measure, and is impressed with the global network taking shape. "The energy we feel from all organizers is extremely motivating and we look forward to seeing LibreLocal events spread even wider over the next years! We want to support these initiatives even more, so we'll be looking to build a network of sponsors for future iterations as we work towards May 2027," says Heshan de Silva-Weeramuni, FSF program manager... William Goodspeed, the organizer behind the Beijing LibreLocal, reported that their meetup was double the size of last year's, and a number of very rich collaborative projects have emerged among the attendees. Discussing the value of connecting people, de Silva-Weeramuni notes: "Free software supporters know that connecting with each other leads them to learn, experiment, and create great things that protect our individual and shared rights. The extraordinary contributions that free software has made to the world were born through such collaborations between like-minded people towards a freer society. This same global spirit of collectively building a better future is one of the inspiring things that we have once again seen unfold through this year's many LibreLocals."
