Security leftovers

  • Security updates for Monday [LWN.net]

    Security updates have been issued by Debian (chromium, containerd, kernel, ntfs-3g, and vlc), Fedora (buildah and logrotate), Red Hat (xz), and SUSE (google-gson, netty3, rubygem-sinatra, and u-boot).

  • Cryptanalysis of ENCSecurity’s Encryption Implementation - Schneier on Security

    ENCSecurity markets a file encryption system, and it’s used by SanDisk, Sony, Lexar, and probably others. Despite it using AES as its algorithm, it’s implementation is flawed in multiple ways—and breakable.

  • Practical bruteforce of AES-1024 military grade encryption – Kudelski Security Research [Ed: Proprietary software is not military-grade, it is degraded; Encryption that works isn't difficult to implement, but it makes your life and your project difficult because states begin to interfere and demand back doors]

    I recently presented work on the analysis of a file encryption solution that claimed to implement “AES-1024 military grade encryption“. Spoiler alert: I did not break AES, and this work does not concern the security of AES. You may find advanced research regarding this topic.

    This project started during a forensic analysis. One of my colleagues came with a USB stick containing a vault encrypted with SanDisk Secure Access software. He asked me if it was possible to bruteforce the password of the vault to recover the content. I did not know this software thus, I started to research. It appeared that this solution is distributed by Sandisk by default on any storage device you buy from them.

  • 7 simple bot detection methods that won’t inconvenience users

    Millions of (poorly coded) bots relentlessly crawl the web to detect and spew junk content into any form they find. The go-to countermeasure is to force everyone to complete a Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA).

  • Kubernetes security risks that keep developers up at night

    In a recent Red Hat survey of more than 300 production-level Kubernetes users, 93% of respondents admitted to experiencing at least one security incident in their Kubernetes environments during the previous year—and 31% of respondents say they experienced revenue or customer loss during that year as a consequence.

    Our industry can do better. This article summarizes findings from the survey, reported in our 2022 State of Kubernetes security report, and highlights the weak points of Kubernetes security today along with a path forward involving DevSecOps.

Most malware targets and infects Windows, but...

    • Quick and Simple: BPFDoor Explained [Ed: Most malware targets and infects Windows, but this one "mostly Linux operating systems" so media goes into "man bites dog" mode]

      BPFDoor is a piece of malware associated with China-based threat actor Red Menshen that has hit mostly Linux operating systems. It's undetected by firewalls and goes unnoticed by most detection systems — so unnoticed that it's been a work in progress over the last five years, going through various phases of development and complexity.

  • New Syslogk Linux rootkit uses magic packets to trigger backdoor [Ed: And yet another sloppy attempt to associate Linux with "back doors" when it fact it's Windows that has back doors, whereas on Linux you have to install some kind of malware to penetrate the system]

    A new Linux rootkit malware named ‘Syslogk’ is being used in attacks to hide malicious processes, using specially crafted "magic packets" to awaken a backdoor laying dormant on the device.

    The malware is currently under heavy development, and its authors appear to base their project on Adore-Ng, an old open-source rootkit.

  • This new Linux malware has a sneaky way of staying hidden [Ed: Microsoft boosters are very eager this year to constantly name Linux as a security threat while the real issue, constantly, is Windows; Microsoft is not even patching actively-exploited holes]

    A newly discovered stealthy piece of Linux malware called Syslogk delivers a backdoor that remains hidden on targeted machine until its controller, from anywhere on the internet, transmits so-called 'magic packets'.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
