📰 AI Helped Uncover A "50-80x Improvement" For Linux's IO_uring
Linux block maintainer and IO_uring lead developer Jens Axboe recently was debugging some slowdowns in the AHCI/SCSI code with IO_uring usage. When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to the Linux kernel...

AppManager
GTK/Libadwaita developed desktop utility in Vala that makes installing and uninstalling #AppImages on #Linux desktop painless. It supports both SquashFS and DwarFS AppImage formats, features a seamless background auto-update process, and leverages zsync delta updates for efficient bandwidth usage. Double-click any .AppImage to open a macOS-style drag-and-drop window, just drag to install and AppManager will move the app, wire up desktop entries, and copy icons.
Features
Drag-and-drop installer: Mimics the familiar macOS Applications install flow.
Smart install modes: Can choose between portable (move the AppImage) and extracted (unpack to ~/Applications/.installed/AppRun) while letting you override it.
Desktop integration: Extracts the bundled .desktop file via 7z or dwarfs, rewrites Exec and Icon, and stores it in ~/.local/share/applications.
Simple uninstall: Right click in app drawer and choose Move to Trash, can uninstall in AppManager or simply delete from ~/Applications folder.
Install registry + preferences: Main window lists installed apps, default mode, and cleanup behaviors, all stored with GSettings.
Background app updates: Optional automatic update checks with configurable interval (daily, weekly, monthly) and notifications when updates are found.
Your Linux AppImages don't need to be disorganized.

How to Anonymize Your Linux System with Whoami
#Whoami is a comprehensive toolkit that can anonymize a running #Linux session. It comes with scripts that can hide your machine’s real IP address, change its default DNS resolvers, and secure your browser. This article will show you how to install Whoami and run some of its modules to anonymize your Ubuntu system.
Note: Don’t confuse this with the whoami command that displays the username of the current user. Also, Whoami works for any Debian and Arch based distro.

📦 Прохождение Linux-машины средней сложности SANDWORM HackTheBox.
• Sandworm — это машина средней сложности на #Linux, которая содержит веб-приложение с сервисом проверки PGP, уязвимым к инъекции шаблонов на стороне сервера (SSTI), что приводит к выполнению удалённого кода (RCE) внутри изоляции Firejail. В этой изоляции можно обнаружить текстовые учетные данные, позволяющие получить доступ по SSH к машине от имени одного из пользователей.
• Далее обнаруживается cron-задача, которая компилирует и запускает бинарник на Rust. Программа использует настраиваемый внешний модуль логирования, к которому у пользователя есть доступ на запись, что затем используется для получения шелл от имени пользователя atlas, запускающего cron-задачу. Наконец, используется недавний эксплойт Firejail (CVE-2022-31214) для создания песочницы, в которой атакующий может выполнить команду su и получить оболочку root на целевой системе.
