  • Blind SQL Injection Techniques Tutorial

    SQL Injection is a type of database attack in which an attacker tries to steal information from a web application’s database. This can even result to remote code execution depending upon web application environment and database version.

    SQL Injection happens due to poor sanitization of user input. If you take input from user in some coding language (PHP, ASP.NET) and pass it directly to server’s database without applying any filter on the input, this can result to SQL Injection vulnerability.

    For example, the following PHP code is vulnerable to SQL Injection attack because its directly passing the user input to database. Attacker can craft its own malicious database query to extract data from database.

  • New HiddenWasp Linux Malware Focused Solely on Achieving Targeted Remote Control [Ed: The media likes to frame this as a "Linux" issue even though it targets something else in order to take control of the underlying OS. Facts don't matter these days.]
  • Pi-hole

    With the recent move by Google to disable the ad-blockers in Chrome (except for Enterprise level customers[1]), the interest is sure to increase for methods of protection against the ad-delivered malware, other than browser plug-ins. I'm sure Barracuda will make some coin if it's still around. And on the free software side, someone is making an all-in-one package for Raspberry Pi, called "Pi-hole". It works by screwing with DNS, which is actually an impressive demonstration of what an attack on DNS can do.

    An obvious problem with Pi-hole is what happens to laptops when they are outside of the home site protection. I suppose one could devise a clone of Pi-hole that plugs into the dnsmasq. Every Fedora system runs one, because NM needs it in order to suppord the correct lookup on VPNs. The most valuable part of Pi-hole is the blocklist, the rest is just scripting.

  • How many browser tabs do you usually have open?

    Here's a potentially loaded question: How many browser tabs do you usually have open at one time? Do you have multiple windows, each with multiple tabs? Or are you a minimalist, and only have a couple of tabs open at once. Another option is to move a 20-tabbed browser window to a different monitor so that it is out of the way while working on a particular task.

  • 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.
