  • Caddy offers TLS, HTTPS, and more in one dependency-free Go Web server

    Yesterday, the Caddy Web server reached an important milestone, with its 2.0.0 release. Caddy bills itself as "The Ultimate Server," with no dependencies, automatic TLS certificate obtainment and renewal, and much smaller configuration files than Apache or Nginx.

  • Researchers Find New Kaiji Botnet Targeting IoT, Linux Devices [Ed: This is not a "Linux" issue but a bad password/design issue]

    A new botnet has been infecting internet of things devices and Linux-based servers, to then leverage them in distributed denial-of-service (DDoS) attacks. The malware, dubbed Kaiji, has been written from scratch, which researchers say is “rare in the IoT botnet landscape” today.

  • ‘Kaiji’ Malware Targets Linux Servers, IoT Devices Via DDoS Attacks [Ed: "Kaiji uses a brute force attack to target IoT devices and Linux servers that have their SSH ports exposed on the internet." So it is not a Linux issue.]
  • Don't Take Cloud Security For Granted [Ed: "Some open-source licenses, such as GPL, can render software unsuitable for some production uses," it says. How much does Microsoft pay Forbes? This is nonsense.]

Kaiji Botnet Targets Linux Servers, IoT Devices

  • Kaiji Botnet Targets Linux Servers, IoT Devices

    The Kaiji malware has the capability of launching distributed denial-of-service attacks, according to researchers from Intezer as well as MalwareMustDie - an independent white hat security research group. But it does not appear that any attacks stemming from this botnet have been launched so far, the reports note.

    What makes Kaiji unusual is that its operators created the botnet from scratch using the Go or Golang programming language, according to the researchers. In most other cases, botnets are created by building on top of existing source code, such as the code used to create Mirai, or by using black-market toolsets.

  • Kaiji: New Chinese Linux malware turning to Golang

    It is not often that you see a botnet’s tooling written from scratch. The Internet of things (IoT) botnet ecosystem is relatively well-documented by security specialists. New threat actors are generally discovered quickly due to the inherent noise caused by DDoS operations, both in terms of infecting new machines and conducting operations. Simply, it is difficult to hide such overt activities. Most DDoS actors do not invest resources in creating custom tooling, unless they require specific capabilities, and resort to using well-known botnet implants (e.g. Mirai, BillGates).

  • New ‘Kaiji’ Linux Malware Targeting IoT Devices

    Intezer came across this piece of Linux malware in April, when the security firm’s researchers observed the botnet targeting IoT devices and servers with SSH brute-force techniques. They also noticed that the threat, dubbed “Kaiji” for one of its function names, differed from other IoT botnets in that it didn’t derive much of its attack functionality from established malware families, such as the open-source Mirai. Instead, those responsible for the malware had written Kaiji entirely from scratch using Golang, a rare programming language for the IoT botnet scene.

  • 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.
