xz-utils backdoor situation (CVE-2024-3094)

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Background

On March 29th, 2024, a backdoor was discovered in xz-utils, a suite of software that

JetBrains Activation MacOS/Windows

1. Proxifier method

Right now, the easiest way to activate JetBrains products is to use redirection of all requests from the application to localhost, but then nothing will work for you, neither pull/push git nor other plugins that use Internet access.

There is a better way, we will forward requests only to those that will go to the address account.jetbrains.com. This can be done without using the program, but it seems to me the easiest way to do it is through Proxifier. This program is available for both Windows and macOS.

AppArmor

  1. AppArmor là gì?
  2. Có các chức năng gì?
  3. Cấu hình như thế nào?

AppArmor

  1. AppArmor là một công cụ cho phép quản lý các chương trình, cho phép giới hạn quyền truy cập vào các file trên hệ thống với một program.

Khác với window's UAC, trao quyền cho user, AppArmor giới hạn khả năng truy cập cho các program

Created November 7, 2016 22:29
Notes on linux memory management options to prioritize and control memory access using older ulimits, newer cgroups and overcommit policy settings. Mostly as an attempt to keep a desktop environment responsive and avoid swap thrashing under high memory pressure.

Overview

Some notes about:

  • Explaining why current day Linux memory swap thrashing still happens (as of 2016).
  • Mitigating "stop the world" type thrashing issues on a Linux workstation when it's under high memory pressure and where responsiveness is more important than process completion.
  • Prioritizing and limiting memory use.
  • Older ulimit versus newer CGroup options.

These notes assume some basic background knowledge about memory management, ulimits and cgroups.
