    The polkit local privilege escalation bug (tracked as CVE-2021-3560) was publicly disclosed, and a fix was released on June 3, 2021.

  • Spear Phishing Explained – Linux Hint

  • Clone Phishing Attacks Explained – Linux Hint

    Clone phishing attacks consist of forging a genuine service or application login form, making the victim believe he is logging in a legitimate form to grab his credentials.
    Clone phishing is possibly the most known technique in social engineering-based hacking attacks. One of the most known examples of this type of attack is the massive mail delivery of messages pretending to be a service or social network. The message encourages the victim to press a link pointing to a fake login form, a visual clone of the real login page.

    The victim of this type of attack clicks on the link and usually opens a fake login page and fills the form with his credentials. The attacker harvests the credentials and redirects the victim to the real service or social network page without the victim knowing that he has been hacked.

    This type of attack used to be effective for attackers who launched massive campaigns in collecting big amounts of credentials from negligent users.

    Luckily, two-step verification systems are neutralizing clone phishing threats but many users remain unaware and unprotected.

  • 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.
