  • 'Critical' Denial-of-Service Bug Patched in Facebook Fizz

    A critical denial-of-service (DoS) vulnerability was found in Facebook Fizz, the social media giant's open source implementation of the Transport Layer Security (TLS) protocol, Semmle reports.

  • Facebook patches denial-of-service flaw in its open-source Fizz TLS implementation

    Facebook last month patched a critical denial-of-service vulnerability in Fizz, its open-source implementation for Transport Layer Security protocol TLS 1.3, researchers have reported.

    Unauthenticated remote attackers could exploit the flaw to create an “infinite loop,” causing the web service to be unavailable for other users and thus disrupting service, according to a March 19 blog post from Semmle, whose researcher Kevin Backhouse uncovered the issue.

    And because Facebook made Fizz’s source code available for public use last August, other web services can potentially be attacked this way as well if they fail to apply secure updates.

  • NSA Opts for Open-Source Sleuthing of Cyber Threats

    Cyber security is taking an open-source step forward with the National Security Agency's release of tools designed to reverse-engineer malware that holds people and companies hostage when their systems become infected.

    Unveiled at the recent RSA security conference in San Francisco, the NSA's Ghidra application for disassembling machine-instruction code covers a spectrum of operating systems and chip architectures for data centers and devices alike. By making the tool an open source kit, the Defense Department's top secret data intelligence agency is enlisting private developers to help it fight cyber crime.

  • Coalfire Labs Develops Open Source Password Cracking Tool

    Coalfire, a trusted provider of cybersecurity advisory and assessment services, announced today that the Coalfire Labs Research and Development (R&D) team released NPK, an open source tool that provides unprecedented password cracking capabilities to break the security surrounding hashed passwords.

    The distributed hash-cracking platform is built entirely of serverless components in Amazon Web Services (AWS) including Cognito, DynamoDB, and S3. It leverages the exceptionally powerful GPU instances in AWS to bring staggering hash cracking performance to a price tier in reach of a weekend tinkerer. It was designed for easy deployment and flexible usage.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
