  • Secure Socket Layer SSL analysis with sslstrip in Kali Linux 2021

    SSL analysis (Secure Socket Layer) is a standard security technology used for establishing an encrypted channel between a server and a client. For example a web server (website) and a browser; or a mail server and a mail client.

    SSL allows sensitive information such as credit card numbers, social security numbers, and login credentials to be transmitted securely. Normally, data sent between browsers and web servers is sent in plain text—leaving you vulnerable to eavesdropping. If an attacker is able to intercept (capture) all data being sent over the internet between a browser and a web server they can see and use that information. Http is sent data in plain text over a network. HTTPS protocol is used for establishing secure channel between browser (client) and the web server.

  • This minor Linux bug fix created a much more serious problem [Ed: Notice how media calls GNU just "Linux" as if GNU does not exist or is a sub-project of the kernel]

    While studying the patch for a recently fixed vulnerability in the GNU C library (glibc), cybersecurity engineers discovered another issue, which they say affected every Linux distro.

    CloudLinux engineer Nikita Popov chanced upon what can essentially be classified as a denial-of-service vulnerability in the upstream glic. Popov believes the bug, tracked as CVE-2021-38604, can be exploited to cause a segmentation fault, causing an application to crash.

  • I was offered $500k as a thank-you bounty for pilfering $600m from Poly Network, says crypto-thief • The Register

    The mysterious miscreant who exploited a software vulnerability in Poly Network to drain $600m in crypto-assets, claims the Chinese blockchain company offered them $500,000 as a reward for discovering the weakness.

    Most of the digital funds have been returned over several transactions. “We appreciate you sharing your experience and believe your action constitutes white hat behaviour ... Since, we believe your action is white hat behaviour, we plan to offer you a $500,000 bug bounty after you complete the refund fully,” the thief wrote in their transaction metadata, seemingly quoting or paraphrasing a message received from Poly 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.
