  • Jelle Van der Waa: Mini DebConf Hamburg 2019

    The reproducible builds project was invited to join the mini DebConf Hamburg sprints and conference part. I attended with the intention to get together to work on Arch Linux reproducible test setup improvements, reproducing more packages and comparing results.

    The first improvement was adding JSON status output for Arch Linux and coincidently also OpenSUSE and in the future Alpine the commit can be viewed here. The result was deployed and the Arch Linux JSON results are live.

    The next day, I investigated why Arch Linux's kernel is not reproducible.

  • Rogue Raspberry Pi allowed hackers to infiltrate NASA's systems [iophk: "article is missing any relevant details, lack of bureaucracy was not the cause here unlike what is asserted]

    That's according to a recent audit by the agency's Office of Inspector General, which reveals a number of security weaknesses affecting its Jet Propulsion Laboratory (JPL).

    The report claims that multiple IT security control weaknesses "reduce JPL's ability to prevent, detect and mitigate attacks targeting its systems and networks" while "exposing NASA systems and data to exploitation by cybercriminals".

  • Hacking Hardware Security Modules

    This highly technical presentation targets an HSM manufactured by a vendor whose solutions are usually found in major banks and large cloud service providers. It will demonstrate several attack paths, some of them allowing unauthenticated attackers to take full control of the HSM. The presented attacks allow retrieving all HSM secrets remotely, including cryptographic keys and administrator credentials. Finally, we exploit a cryptographic bug in the firmware signature verification to upload a modified firmware to the HSM. This firmware includes a persistent backdoor that survives a firmware update.

  • The looming threat of malicious backdoors in software source code

    The history of backdoors in source code has largely been about managing insider threats. For example, a rogue developer looking to sabotage the organization. What’s changed is that increasingly well-funded nation-state attackers can afford to take a much longer-term view. This means writing useful code with backdoors planted deep inside it, making the code widely available, and waiting to see who adopts it.

  • A Florida city paid a $600,000 bitcoin ransom to hackers who took over its computers — and it's a massive alarm bell for the rest of the US [iophk: "Windows TCO"]

    A Florida city's council voted to pay a ransom of $600,000 in Bitcoin to [crackers] that targeted its computer systems — and the payout is a sign of how unprepared much of the US is to deal with a coming wave of cyberattacks.

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.
