  • Microsoft puts a bullet in blundering D-Link's leaked key that made malware VIPs on PCs

    Microsoft has finally revoked D-Link's leaked code-signing key, which gave malware the red carpet treatment on millions of Windows PCs.

    Last week, it emerged that, for six months between February and September, D-Link exposed its private code-signing key to the world in a firmware download. Anyone who stumbled upon this key could use it to dress up malware as a legit-looking D-Link application, tricking Windows and users into trusting it.

    The key expired at the start of this month, meaning it cannot be used to digitally sign new malware. But any software nasties signed using the key earlier in the year would still be trusted and run by Windows PCs.

  • Filling in the holes in Linux boot chain measurement, and the TPM measurement log

    When I wrote about TPM attestation via 2FA, I mentioned that you needed a bootloader that actually performed measurement. I've now written some patches for Shim and Grub that do so.

    The Shim code does a couple of things. The obvious one is to measure the second-stage bootloader into PCR 9. The perhaps less expected one is to measure the contents of the MokList and MokSBState UEFI variables into PCR 14. This means that if you're happy simply running a system with your own set of signing keys and just want to ensure that your secure boot configuration hasn't been compromised, you can simply seal to PCR 7 (which will contain the UEFI Secure Boot state as defined by the UEFI spec) and PCR 14 (which will contain the additional state used by Shim) and ignore all the others.

  • Would you trust Intel, Vodafone, Siemens et al with Internet of Things security? You'll have to

    A new non-profit foundation dedicated to improving security in the "internet of things" launched on Wednesday.

    More than 30 companies including Intel, Vodafone, Siemens, and BT are the founding members of the foundation, whose mission is to "make the Internet of Things secure, to aid its adoption, and maximize its benefits."

    The IoTSF will focus on best practices and knowledge sharing. It will host a conference in London in December on IoT security.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
