  • Amazon Linux is Amazing - But Still Needs PROTECTing

    While many companies host their Windows and Linux distributions, such as Red Hat, servers in Amazon Web Services (AWS), more and more companies are starting to stand up and run the Amazon version of Linux, called the Amazon Linux Amazon Machine Image (AMI). This flavor of Linux is provided by AWS for use on Amazon Elastic Compute Cloud (Amazon EC2) and even virtualized and local environments.

  • Keybase Pays $5,000 Bounties for Privilege Escalation Bugs in Linux and macOS Apps

    Keybase received two separate reports for security issues in its app for Linux and macOS that led to privilege escalation on the system. For each of them, the developer paid a bounty of $5,000.

    Both reports came via the HackerOne bug bounty platform, the first one submitted by Adam Chester on August 21 for the Keybase Desktop app for macOS.

  • Hacker Discloses New Unpatched Windows Zero-Day Exploit On Twitter

    A security researcher with Twitter alias SandboxEscaper today released proof-of-concept (PoC) exploit for a new zero-day vulnerability affecting Microsoft's Windows operating system.
    SandboxEscaper is the same researcher who previously publicly dropped exploits for two Windows zero-day vulnerabilities, leaving all Windows users vulnerable to the hackers until Microsoft patched them.
    The newly disclosed unpatched Windows zero-day vulnerability is an arbitrary file read issue that could allow a low-privileged user or a malicious program to read the content of any file on a targeted Windows computer that otherwise would only be possible via administrator-level privileges.

  • 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.
