Ah yes, because who doesn't want to spend their weekend parsing ELF headers and translating memory access while pretending they understand #Armv7 CPU emulation? 🤓 By the end of this 8,336-word epic, you'll be the life of the party with your newfound ability to forward syscalls and handle exception exits. 🎉 #Goals

Привет, Хабр! В этой статье рассмотрим работу с системными утилитами в Go. Будем напрямую общаться с ядром, дергать системные вызовы и писать код на C, чтобы Go не чувствовал себя одиноким.

Как часто менеджерам, дизайнерам и UX-исследователям приходится вникать в проблемы сетевого стека Linux-ядра? Подозреваю, что не часто. Но если вам пришлось это сделать, у меня хорошая новость! Я уже прошла этот путь, полный админских терминов и бесконечных аналогий, и подготовила краткое содержание в комиксах. Теперь вам не нужно будет переводить с технического на дизайнерский!

Roughly two years ago I hacked together a small tool to automatically download the
#windows #docker images, extract the ntdll.dll from them and extract the #syscall numbers for that Windows version. This can be used for #shellcode and other #malware dev activities.

I've finally pushed the code to GitHub and redeployed the website.

All the data is either available in the HTML tables, or as a JSON by appending ?format=json to the URL.

Because it's just been redeployed, it's re-downloading all the images, so it will take a few hours until more Windows versions are indexed.

Updated the article: Monitor file access by Linux processes

Linux is powerful with the help of small utilities like lsof and strace. They help with monitoring disk and file activity, of new and running processes. #linux #lsof #ltrace #strace #syscall

Учимся понимать события подсистемы аудита Linux

Приветствую всех любителей изучать новое. Меня зовут Рома, и я занимаюсь исследованием безопасности ОС Linux в экспертной лаборатории PT Expert Security Center . В рамках инициативы нашей компании по обмену экспертными знаниями с сообществом я расскажу вам об известной многим администраторам системе журналирования в Linux-подобных ОС — подсистеме аудита Linux (auditd). При должной настройке она позволяет получать полную информацию о действиях, выполняемых в операционной системе. Специалистам по информационной безопасности полезно уметь расшифровывать и обрабатывать события auditd для отслеживания потенциально вредоносной активности. В связи с этим нам потребовалось организовать для них экспертную поддержку в системе мониторинга событий ИБ и управления инцидентами MaxPatrol SIEM . Подробнее

If your #NYE2023 resolution is to learn more about the #linux #kernel then we have you covered with this #EverythingOpen retro talk from #IBM's Rohan McLure, who walks us through his first kernel patch submission, which broke the #ABI. He takes us on a deep dive into #syscall and #architecture, and how he learned a lot by breaking things.
