  • Fundamental Flaw in RNGs Affects Many IoT Devices | Decipher

    The hardware-based random number generators used in most modern IoT devices have a serious fundamental weakness that undermines the security of the encryption keys they generate for communications: The RNGs don’t really generate random numbers.

    That’s a fairly serious issue when the whole function of the RNG is to generate random numbers, which are then used as seeds for encryption keys. Researchers from Bishop Fox found that the overwhelming majority of the tens of billions of IoT devices in use today have flawed RNGs, a vulnerability that is not limited to a group of vendors or specific IoT operating systems. It’s a widespread problem that security researchers have been discussing in various forms for some time, and there’s no simple way to address it.

  • Retail sector top target for ransomware attack in 2020: Report [iophk: Windows TCO]

    The global retail sector faced the highest level of ransomware attacks during 2020, with 44 per cent of organisations hit (compared to 37 per cent across all industry sectors), according to a report by UK-based cybersecurity firm Sophos on Wednesday.

  • Another big company hit by a ransomware attack

    Accenture (ACN)'s encrypted files will be published by the group on the dark web on Wednesday unless the company pays the ransom, LockBit claimed, according to screenshots of the website reviewed by CNN Business and Emsisoft, a cybersecurity firm.

    Stacey Jones, an Accenture spokesperson, confirmed a cybersecurity incident to CNN Business on Wednesday, but did not explicitly acknowledge a ransomware attack.

  • Zoom’s new focus mode could keep students from distracting each other

    Zoom has announced a new Focus mode, which it says is meant to keep students from getting distracted while in a virtual classroom, while still allowing the teacher to keep an eye on everybody. When activated, Focus mode will make it so that a meeting’s participants won’t be able to see each other’s videos or screen shares, while the host is still able to see everyone’s webcams. It provides some of the control found in Webinar mode, without the complexity and lack of flexibility that comes with it — for instance, a teacher could turn on Focus mode while presenting, and then turn it off when it’s time for a class discussion. And, while hosting a Webinar costs money, Focus mode appears to be available to free accounts, based on my testing.

  • Achieving SOC2 Compliance for Teleport Cloud with Teleport On-Prem

    SOC2 has a few control areas related to SSH management. Teleport goes beyond what’s typically required, and we hope that SOC2 requirements will eventually be updated to make using certificates the expectation.

  • 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.
