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 experience accelerated development and debugging, but raised concerns about code quality, application security, abstraction, and the faster accumulation of technical debt. ### Source excerpt AI will be the high interest credit card of 2023 I haven't done a lot of work in Python, and I've never used it to produce graphs. But after an hour of pair programming and then using Chatgpt and Github Copilot got me quite far in writing a set of Jupyter Notebooks, and dramatically shrunk the effort to use and debug a new tool. I wanted to record some thoughts on the experience, and what it means for programming and for application security. ## AppSecPNW 2023 DevFeed: [AppSecPNW 2023]() Original publisher: [Read original article]() Author: Adam Published: 2023-06-12T00:00:00Z Content type: opinion Language: en Sources: [Shostack & Friends Blog]() Topics: [Application Security]() Tags: [appsec](), [event](), [keynote]() ### AI overview The author reports delivering the opening keynote at OWASP's AppSec PNW 2023 in Portland and provides the presentation slides. ### Source excerpt Adam's AppSecPNW 2023 keynote ## The Appsec Landscape in 2023 DevFeed: [The Appsec Landscape in 2023]() Original publisher: [Read original article]() Author: Adam Published: 2023-01-05T00:00:00Z Content type: article Language: en Sources: [Shostack & Friends Blog]() Topics: [Application Security](), [Security](), [Requirements](), [open-source-security]() Tags: [appsec](), [changes](), [circleci](), [driving](), [external](), [government](), [legacy](), [requirements](), [secure-software](), [ssdf](), [supply-chain]() ### AI overview This article examines how economic conditions, new regulations, and engineering considerations may shape application security decisions in 2023.
