  • Google Publishes "Leaky.Page" Showing Spectre In Action Within Web Browsers

    Google has published their proof-of-concept code showing the practicality of Spectre exploits within modern web browsers' JavaScript engines. The code is out there and you can even try it for yourself on the leaky.page web-site.

    Google's Leaky.Page code shows its possible to leak data at around 1kB/s when running their Chrome web browser on a Skylake CPU. The proof-of-concept code is catering to Intel Skylake CPUs while it should also work for other processors and browsers with minor modifications to the JavaScript. Google was also successful in running this Leaky.Page attack on Apple M1 ARM CPUs without any major changes.

  • Hackers Are Swarming Microsoft Exchange [Ed: Crackers, not "hackers"]

    Those Microsoft Exchange security flaws you may have heard about are really getting pummeled. If ever there was a time for cybersecurity reporters to trot out metaphors involving phrases like “blood in the water” and maybe “deranged swarm of piranhas,” it might be right now.

    [...]

    Instead, ESET reports that Exchange is basically getting pillaged by close to a dozen different groups, all of which have names that sound like bad gamertags, including Tick, LuckyMouse, Calypso, Websiic, Winnti, TontoTeam, Mikroceen and DLTMiner. There are also apparently two other hacker groups that have not yet been identified. So, yeah, it’s a pretty big mess.

    The hacking seems to have picked up directly after Microsoft released its patches, too, as ESET’s report states that “the day after the release of the patch” security researchers “started to see many more threat actors (including Tonto Team and Mikroceen) scanning and compromising Exchange servers en masse.”

  • Critics fume after Github removes exploit code for Exchange vulnerabilities

    Github has ignited a firestorm after the Microsoft-owned code-sharing repository removed a proof-of-concept exploit for critical vulnerabilities in Microsoft Exchange that have led to as many as 100,000 server infections in recent weeks.

    ProxyLogon is the name that researchers have given both to the four Exchange vulnerabilities under attack in the wild and the code that exploits them. Researchers say that Hafnium, a state-sponsored hacking group based in China, started exploiting ProxyLogon in January, and within a few weeks, five other APTs—short for advanced persistent threat groups—followed suit. To date, no fewer than 10 APTs have used ProxyLogon to target servers around the world.

  • Microsoft confirms Windows 10 crash issue due to March updates [Ed: Even dedicated Microsoft boosters point out these issues]

    Microsoft has confirmed that Windows 10 devices might crash with a Blue Screen of Death (BSOD) when printing under certain conditions after applying the March cumulative updates.

  • Microsoft March 2021 Patch Tuesday fixes 82 flaws, 2 zero-days

    Today is Microsoft's March 2021 Patch Tuesday, and with admins already struggling with Microsoft Exchange updates and hacked servers, please be nice to your IT staff today.

  • 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.
