  • An Inside Look at a K-12 Ransomware Incident (Part 2) [Ed: Responsible teachers and pupils don't use Microsoft Windows in schools]

    In 2020, there were 408 publicly-disclosed cyber incidents impacting K-12 school districts. Of those 408 incidents, roughly 50 consisted of ransomware. These incidents often resulted in school closures and prevented districts from accessing sensitive data and critical systems because they were encrypted by cybercriminals.

    During an attack, school district IT teams scramble to find all the ransomware symptoms to see which systems have been impacted and assess the severity. Another threat emerging is the exfiltration of data by attackers to try and force school districts to pay the ransom. This makes data loss prevention for districts more critical to have in place as part of their cloud application security checklist.

  • WebSpec, a formal framework for browser security analysis, reveals new cookie attack

    Folks at Technische Universität Wien in Austria have devised a formal security framework called WebSpec to analyze browser security.

    And they've used it to identify multiple logical flaws affecting web browsers, revealing a new cookie-based attack and an unresolved Content Security Policy contradiction.

    These logical flaws are not necessarily security vulnerabilities, but they can be. They're inconsistencies between Web platform specifications and the way these specs actually get implemented within web browsers.

    WebSpec was developed by Lorenzo Veronese, Benjamin Farinier, Mauro Tempesta, Marco Squarcina, Matteo Maffei in an effort to bring rigor to web security through automated, verifiable rule checking rather than manual evaluation.

  • Wireshark 3.6.1

    Wireshark is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible. You could think of a network packet analyzer as a measuring device used to examine what's going on inside a network cable, just like a voltmeter is used by an electrician to examine what's going on inside an electric cable (but at a higher level, of course). In the past, such tools were either very expensive, proprietary, or both. However, with the advent of Wireshark, all that has changed. Wireshark is perhaps one of the best open source packet analyzers available today.

  • Latest web hacking tools – Q1 2022 | The Daily Swig

    After our recent end-of-year retrospectives, it’s time to look back again – this time at some of the most compelling open source hacking tools released during the final quarter of 2021.

    The arsenals of pen testers, researchers, and bug hunters have been bolstered for 2022 by new tools for detecting dependency confusion attacks, finding novel HTTP request smuggling techniques, and uncovering leaked, paired private and public keys that are potentially dangerous.

  • Key Considerations for Canada’s Forthcoming National Cyber Security Strategy

    On December 16, Prime Minister Justin Trudeau released mandate letters tasking his ministers of national defense, foreign affairs, public safety, and industry to develop a new “National Cyber Security Strategy.” He specifically highlighted the need for the strategy to “articulate Canada’s long-term strategy to protect our national security and economy, deter cyber threat actors, and promote norms-based international behavior in cyberspace,” as quoted by Global News.

  • 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.
