  • New Linux 'Mutagen Astronomy' security flaw impacts Red Hat and CentOS distros

    This is a type of vulnerability that requires an attacker to have a foothold on a vulnerable system, but it's one of those security flaws that can turn a simple hack into a very bad one, as it can be used to give an intruder root access and complete control over infected systems.

  • Responsible disclosure: retrieving a user's private Facebook friends.

    Data access control isn’t easy. While it can sound quite simple (just give access to the authorized entities), it is very difficult, both on a theoretical side (who is an authorized entity? What does authorized mean? And how do we identify an entity?) and on a pratical side.

    On the pratical side, how we will see, disclose of private data is often a unwanted side effect of an useful feature.

    Facebook and Instagram

    Facebook bought Instagram back in 2012. Since then, a lot of integrations have been implemented between them: among the others, when you suscribe to Instagram, it will suggest you who to follow based on your Facebook friends.

    Your Instagram and Facebook accounts are then somehow linked: it happens both if you sign up to Instagram using your Facebook account (doh!), but also if you sign up to Instagram creating a new account but using the same email you use in your Facebook account (there are also other way Instagram links your new account with an existing Facebook account, but they are not of our interest here).

    So if you want to create a secret Instagram account, create a new mail for it Wink

    Back in topic: Instagram used to enable all its feature to new users, before they have confirmed their email address. This was to do not “interrupt” usage of the website / app, they would have been time to confirm the email later in their usage.

    Email address confirmation is useful to confirm you are signing up using your own email address, and not one of someone else.

  • 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.
