  • A mysterious threat actor is running hundreds of malicious Tor relays

    Since at least 2017, a mysterious threat actor has run thousands of malicious servers in entry, middle, and exit positions of the Tor network in what a security researcher has described as an attempt to deanonymize Tor users.

    Tracked as KAX17, the threat actor ran at its peak more than 900 malicious servers part of the Tor network, which typically tends to hover around a daily total of up to 9,000-10,000.

    Some of these servers work as entry points (guards), others as middle relays, and others as exit points from the Tor network.

    Their role is to encrypt and anonymize user traffic as it enters and leaves the Tor network, creating a giant mesh of proxy servers that bounce connections between each other and provide the much-needed privacy that Tor users come for.

    Servers added to the Tor network typically must have contact information included in their setup, such as an email address, so Tor network administrators and law enforcement can contact server operators in the case of a misconfiguration or file an abuse report.

  • Someone Is Running Lots of Tor Relays

    Since 2017, someone is running about a thousand — 10% of the total — Tor servers in an attempt to deanonymize the network...

  • 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.
