The article describes malicious code executed during RubyDoc documentation builds, data collection from British municipal websites, attempts to obtain RubyGems API keys, and a caching flaw involving legacy keys. RubyGems said it could not independently identify the package creators and found no evidence that чужие keys were successfully obtained. ### Source excerpt 11 сентября исследователи Nightingale Collective опубликовали разбор RubyHack и связали майскую кампанию в RubyGems с внутренними агентами OpenAI. По их версии, скрипты внутри пакетов запускали код в инфраструктуре RubyDoc, собирали открытые данные с сайтов британских муниципалитетов и публиковали результаты обратно в реестр. В нескольких образцах исследователи также обнаружили попытки получить чужие API-ключи RubyGems. Команда RubyGems не смогла независимо установить, кем именно были созданы пакеты, и не нашла доказательств успешного получения чужих ключей. Во время майской кампании она отозвала вредоносные пакеты и на четыре дня остановила регистрацию новых пользователей. Одной из точек входа стала обычная сборка документации. В пакет добавляли .yardopts - файл параметров генератора YARD - с указанием загрузить Ruby-скрипт. Когда для пакета запрашивали документацию на RubyDoc, сборщик обрабатывал этот файл и запускал вложенный код. Такое поведение соответствует механике самого YARD: параметр --load загружает указанный Ruby-файл перед выполнением команды. Запущенный скрипт обращался к муниципальным сайтам, сохранял ответы, собирал из них новый .gem-архив и отправлял его в RubyGems со встроенным ключом. В результате реестр использовался как канал передачи и хранения собранных данных. Установка такого пакета множеством разработчиков для работы этой схемы не требовалась: достаточно было исполнения кода в сервисе сборки документации. Отдельные пакеты обращались к старому endpoint выдачи API-ключей. В нём действовала ошибка кэширования: при определённых условиях CDN мог сохранить ответ с legacy-ключом и до часа отдавать его следующим запросам на том же узле. RubyGems исправил проблему 9 июля, очистил кэш, отозвал legacy-ключи и затем отключил старый endpoint.

The packages reportedly used suspicious naming and access patterns, exploited the RubyDoc.info documentation build process to exfiltrate public UK government data, and attempted to steal API keys, though the success of those attempts is unclear. ### Source excerpt OpenAI agents carried out an undisclosed attack on RubyGems is a new bombshell report from Spencer Kitts, Thomas Larsen, and Sydney Von Arx - three of the four authors of the report on the agent attack on disused wikis (previously) last week. This time they're noting that it looks very likely that an OpenAI agent swarm was behind an attack against the RubyGems package repository first reported on May 12th by Maciej Mensfeld of the RubyGems security team: We're dealing with a major malicious attack on @rubygems right now. Signups are paused for the time being. Hundreds of packages involved - mostly targeting us, but some carrying exploits. The team has been on this for hours. More details to follow once we're through it. Those packages turned out to carry some very suspicious patterns: Many of them included "oai" in their name, or the author field, or the fake email address they provided. The files they were accessing were similar in character to the files retrieved by the wiki agents, using similar tricks (r.jina.ai) - and OpenAI have confirmed the wiki agents were theirs. The code in the packages appeared to be LLM-authored. I find point 2 the most convincing, given what we learned from the wiki attack when it was analyzed in September. Many of the packages were exploiting the RubyDoc.info documentation build process to exfiltrate (public) data from UK government websites, presumably as part of an information gathering task similar to the research tasks processed by the wiki-exploiting agents. We know this because one agent helpfully left a comment: # malicious crawler/exfil for Southwark Jan 2026 docs via rubydoc.info worker They also attempted to steal API keys via an exploit that was patched over two months later - it's not clear if those attempts were successful. The thing that bothers me most about this incident is that the authors report that OpenAI had not disclosed to RubyGems that they were responsible for the attack prior to now. If that's true there are ## Claims About RubyGems Caching and RubyDoc Code Execution DevFeed: [Claims About RubyGems Caching and RubyDoc Code Execution]() Original publisher: [Read original article]() Published: 2026-09-12T00:02:11Z Content type: opinion Language: en Sources: [Aaron Patterson]() Topics: [rubygems](), [Caching](), [vulnerability](), [Docker](), [Web Scraping]() Tags: [caching](), [docker](), [rubygems](), [scraping](), [vulnerability]() ### AI overview An opinion post discusses alleged RubyGems activity involving a caching vulnerability and web scraping. It also describes how published gems can cause RubyDoc.info to run YARD-loaded code in a networked Docker container. ### Source excerpt Today Reuters and the Wall Street Journal both reported about rogue AI agents at OpenAI attacking RubyGems.org. https://www.rubyhack.ai/ has an amazing writeup, and you should read it. I just wanted to make a quick post about it because it's wild. TL;DR: It seems like OpenAI Bots knew about the RubyGems caching vulnerability, tried to take advantage of it, and at the same time ran some weird web scraping code on RubyDoc.info. Back in May, socket.dev reported about a "GemStuffer Campaign" where someone (I guess OpenAI) was uploading tons of junk gems to RubyGems.org. For some reason, the gems would scrape UK government websites, then repackage the data as gems, and attempt to upload them to RubyGems. I honestly didn't think much about this (or even look into it) until Sydney Von Arx and Spencer Kitts (both co-authors on https://www.rubyhack.ai) contacted me asking about RubyGems. I thought the claims they were making were completely outlandish until I actually read the code in these "GemStuffer" gems. After reading the code in these gems, a couple things stood out to me. YARD Documentation First, the gems leverage YARD documentation to execute arbitrary code on host machines. In most of the examples you'll see a .yardopts file that looks like this: --load ./script.rb README.md lib/**/*.rb Here's a link to an example. If you have YARD installed, and you install this gem, then YARD will load and run whatever is in ./script.rb from inside the gem. I think it's pretty common knowledge that C extensions will execute extconf.rb (so you basically have an RCE vector), but I was surprised to find out that a documentation tool would do that too. Nobody is going to install a gem named slnleaker5 though, so why would this matter? Well, any time a Gem is published RubyDoc.info will download the gem and process the YARD documentation. RubyDoc.info will execute the arbitrary code inside a Docker container. The Docker container still has network access though, so these gems could ha ## Can Bundler Be as Fast as uv? DevFeed: [Can Bundler Be as Fast as uv?]() Original publisher: [Read original article]() Published: 2025-12-29T20:26:00Z Content type: opinion Language: en Sources: [Aaron Patterson]() Topics: [Ruby](), [rubygems](), [Rust]() Tags: [packaging](), [performance](), [ruby](), [rubygems](), [rust]() ### AI overview The article examines whether Bundler can approach uv's package-installation speed. It reviews performance techniques from uv, considers how they apply to Bundler and RubyGems, and discusses existing bottlenecks and possible improvements. ### Source excerpt At RailsWorld earlier this year, I got nerd sniped by someone. They asked "why can't Bundler be as fast as uv?" Immediately my inner voice said "YA, WHY CAN'T IT BE AS FAST AS UV????" My inner voice likes to shout at me, especially when someone asks a question so obvious I should have thought of it myself. Since then I've been thinking about and investigating this problem, going so far as to give a presentation at XO Ruby Portland about Bundler performance. I firmly believe the answer is "Bundler can be as fast as uv" (where "as fast" has a margin of error lol). Fortunately, Andrew Nesbitt recently wrote a post called "How uv got so fast", and I thought I would take this opportunity to review some of the highlights of the post and how techniques applied in uv can (or can't) be applied to Bundler / RubyGems. I'd also like to discuss some of the existing bottlenecks in Bundler and what we can do to fix them. If you haven't read Andrew's post, I highly recommend giving it a read. I'm going to quote some parts of the post and try to reframe them with RubyGems / Bundler in mind. Rewrite in Rust? Andrew opens the post talking about rewriting in Rust: uv installs packages faster than pip by an order of magnitude. The usual explanation is "it's written in Rust." That's true, but it doesn't explain much. Plenty of tools are written in Rust without being notably fast. The interesting question is what design decisions made the difference. This is such a good quote. I'm going to address "rewrite in Rust" a bit later in the post. But suffice to say, I think if we eliminate bottlenecks in Bundler such that the only viable option for performance improvements is to "rewrite in Rust", then I'll call it a success. I think rewrites give developers the freedom to "think outside the box", and try techniques they might not have tried. In the case of uv, I think it gave the developers a good way to say "if we don't have to worry about backwards compatibility, what could we achieve?".

CococaPods is an awesome dependency manager similar to Rubygems for Objective-C projects. Unfortunately a lot of submitted podspecs haven't been correctly formatted or they're missing required information. CocoaPods has an awesome build in command pod spec lint that allows you to make sure the spec is valid and complete. Understandably people who are new to CocoaPods trying to submit their libraries are unaware of this awesome tool. Therefore when I look through the pull requests, I like to lint them myself (CocoaPods does utilize Travis but unfortunately it can't do everything). Since CocoaPods supports multiple versions of Ruby (1.8.7 and 1.9.3) to be complete ideally you'd lint them on both versions. Tools like RVM and rbenv(my tool of choice) make it easy to quickly switch between different versions of Ruby using .rvmrc and .rbenv-version respectively. As you can probably assume I wanted to automate this. So I wrote a quick Rakefile to do this for me. #!/usr/bin/env rake # NOTE: Must be using rbenv 4.0 to use `system` and `.ruby-version` ## Set your preferred ruby versions $V18 = 'system' $V19 = '1.9.3-p385' $RBENV = '.ruby-version' # The gem to use $GEM = 'cocoapods' task :default => :lint task :c => :clean desc "Lint podspecs on multiple versions of ruby with rbenv" task :lint do if Dir.glob('*.podspec').count < 1 puts "No podspecs in #{ Dir.pwd }" exit end existed = versionFileExists? if existed old_version = currentVersion end # Loop through all podspecs Dir.glob('*.podspec').each do |file| # Loop through ruby versions 2.times do |x| version = x == 0 ? $V18 : $V19 writeVersion(version) puts "Linting #{ file } on Ruby version #{ currentVersion }" puts lint(file) end end # If the dotfile already existed rewrite the original code if existed writeVersion(old_version) else File.delete($RBENV) if versionFileExists? end end desc "Delete all pod ## BorderPatrol: KML border checking in Ruby DevFeed: [BorderPatrol: KML border checking in Ruby]() Original publisher: [Read original article]() Author: Square Engineering Published: 2011-07-05T16:00:00Z Content type: release Language: en Sources: [Square Corner Blog RSS Feed]() Topics: [Ruby](), [Algorithm](), [data](), [benchmarking](), [rubygems](), [Google]() Tags: [algorithm](), [benchmarking](), [data](), [engineering](), [github](), [google-maps](), [performance](), [ruby](), [rubygems]() ### AI overview The article introduces BorderPatrol, a Ruby gem that imports KML files and determines whether points lie within regions defined by polygons.
