  • Security updates for Friday
  • Assessing the threat the Reaper botnet poses to the Internet—what we know now
  • KRACK, ROCA, and device insecurity

    It is a fairly bleak picture from a number of different viewpoints. One almost amusing outcome of this mess is contained near the end of Vanhoef's KRACK web page. He notified OpenBSD of the flaw in mid-July with an embargo (at the time) until the end of August. OpenBSD leader Theo de Raadt complained about the length of the embargo, so Vanhoef allowed OpenBSD to silently patch the flaw. "In hindsight this was a bad decision, since others might rediscover the vulnerability by inspecting their silent patch. To avoid this problem in the future, OpenBSD will now receive vulnerability notifications closer to the end of an embargo." That might not quite be the outcome De Raadt was hoping for with his (quite reasonable) complaint, especially given that Vanhoef strongly hints that there are other WiFi vulnerabilities in the pipeline.

  • A comparison of cryptographic keycards

    An earlier LWN article showed that private key storage is an important problem to solve in any cryptographic system and established keycards as a good way to store private key material offline. But which keycard should we use? This article examines the form factor, openness, and performance of four keycards to try to help readers choose the one that will fit their needs.

    I have personally been using a YubiKey NEO, since a 2015 announcement on GitHub promoting two-factor authentication. I was also able to hook up my SSH authentication key into the YubiKey's 2048 bit RSA slot. It seemed natural to move the other subkeys onto the keycard, provided that performance was sufficient. The mail client that I use, (Notmuch), blocks when decrypting messages, which could be a serious problems on large email threads from encrypted mailing lists.

    So I built a test harness and got access to some more keycards: I bought a FST-01 from its creator, Yutaka Niibe, at the last DebConf and Nitrokey donated a Nitrokey Pro. I also bought a YubiKey 4 when I got the NEO. There are of course other keycards out there, but those are the ones I could get my hands on. You'll notice none of those keycards have a physical keypad to enter passwords, so they are all vulnerable to keyloggers that could extract the key's PIN. Keep in mind, however, that even with the PIN, an attacker could only ask the keycard to decrypt or sign material but not extract the key that is protected by the card's firmware.

  • Google Play Protect is 'dead last' at fingering malware on Android

    Last month, German software testing laboratory AV-Test threw malware at 20 Android antivirus systems – and now the results aren't particularly great for Google.

    Its Play Protect system, which is supposed block malicious apps from running on your handheld, was beaten by every other anti-malware vendor.

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.
