  • Chinese Researchers Detail Linux Backdoor of NSA-Linked Equation Group [Ed: Media desperate to associate Linux with security problem because Ukraine is besieged by attacks on Microsoft Windows at the moment?]

    A team of researchers from China’s Pangu Lab on Wednesday published a 50-page report detailing a piece of Linux malware allegedly used against many targets by the threat actor known as the Equation Group, which has been linked to the U.S. National Security Agency (NSA).

    It’s not uncommon for cybersecurity companies in the United States to publish reports detailing the tools and activities of threat actors linked to the Chinese government, and now a group of Chinese researchers have released a report detailing a piece of malware tied to the U.S. government.

    Pangu Lab is a research project of Pangu Team, which is best known for its iPhone jailbreaks. An iOS exploit earned them $300,000 last year at a major Chinese hacking contest.

  • US, UK detail malware tied to Russian hacking group Sandworm that targets Linux [Ed: They mostly target Microsoft Windows, but pundits try to distort what's actually going on]

    As Russia begins its invasion of Ukrainian territories and Western governments continue to warn about the potential or Russian cyberattacks in response to sanctions, U.S. and UK agencies have detailed what they claim is another malware tool used by Russian APT hacking group Sandworm.

  • New Sandworm Malware Cyclops Blink Replaces VPNFilter

    The United Kingdom’s National Cyber Security Centre, CISA, the National Security Agency, and the Federal Bureau of Investigation have released a joint Cybersecurity Advisory (CSA) reporting that the malicious cyber actor known as Sandworm or Voodoo Bear is using new malware, referred to as Cyclops Blink. Cyclops Blink appears to be a replacement framework for the VPNFilter malware exposed in 2018, which exploited network devices, primarily small office/home office routers and network-attached storage devices.

  • Google Online Security Blog: Mitigating kernel risks on 32-bit ARM

    Linux kernel support for the 32-bit ARM architecture was contributed in the late 90s, when there was little corporate involvement in Linux development, and most contributors were students or hobbyists, tinkering with development boards, often without much in the way of documentation.

  • Biesheuvel: Mitigating kernel risks on 32-bit ARM [LWN.net]

    Ard Biesheuvel writes about 32-bit Arm systems on the Google Security Blog, with a focus on why these processors are still in use and what is being done to increase their security at the kernel level.

  • Anatomy of top-tier suspected NSA backdoor code

    Pangu Lab has identified what it claims is a sophisticated backdoor that was used by the NSA to subvert highly targeted Linux systems around the world for more than a decade.

    The China-based computer-security outfit says it first spotted the backdoor code, or advanced persistent threat (APT), in 2013 when conducting a forensic investigation on a host in "a key domestic department" – presumably a Chinese company or government agency.

  • 'Hundreds of computers' in Ukraine hit with wiper malware

    It's not entirely clear right now how the malware is dropped onto victims' machines and run, though in one case, said ESET, an organization's Active Directory server was probably compromised to distribute the wiper through the network via a group policy object.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
