  • New malware hides as legit nginx process on e-commerce servers

    eCommerce servers are being targeted with remote access malware that hides on Nginx servers in a way that makes it virtually invisible to security solutions.

    The threat received the name NginRAT, a combination of the application it targets and the remote access capabilities it provides and is being used in server-side attacks to steal payment card data from online stores.

  • Testing Phone-Sized Faraday Bags

    Back in the not-so-distant past, if you were patient and knowledgeable enough, you could reverse engineer the behavior of almost any electronic device simply by inspecting it carefully and understanding the circuitry. But those days are rapidly ending. Today, virtually every aspect of complex electronic hardware is controlled by microprocessors and software, and while that's generally good news for functionality, it's also bad news for security (and for having any chance of being sure what, exactly, your gadgets are doing, for that matter). For devices like smartphones, software runs almost every aspect of the user interface, including how and when it's powered on and off, and, for that matter, what being "off" actually means.

    Complex software is, to put it mildly, hard to get right (for details, see almost any other posting on this or any other security blog). Especially for gadgets that are rich with microphones, cameras, location and environmental sensors, and communication links (such as, you know, smartphones), errors and security vulnerabilities in the software that controls them can have serious privacy implications.

    The difficulty of reliably turning software-based devices completely off is no longer merely a hypothetical issue. Some vendors have even recognized it as a marketable feature. For example, certain Apple iPhones will continue to transmit "Find My Device" tracking beacons even after they've ostensibly been powered off. Misbehaving or malicious software could enable similar behavior even on devices that don't "officially" support it, creating the potential for malware that turns your phone into a permanently on surreptitious tracking device, no matter whether you think you've turned it off. Compounding these risks are the non-removable batteries used in many of the latest smartphones.

  • Netgear router vulnerabilities affecting SME products fixed • The Register

    Two arbitrary code execution vulnerabilities affecting a number of Netgear routers aimed at small businesses have been patched following research by Immersive Labs.

    The vulns rely on authenticated access to affected devices so aren't an immediate threat. They do, however, allow someone with remote access to the router to pwn the device's underlying OS, threatening the security of data passing through the router.

    Helpfully, Netgear itself publishes default login credentials for "most" of its products on its website. If you haven't been into your Netgear router's admin panel and changed these default creds, you're at increased risk.

  • Netgear vulnerabilities could put small business routers at risk

    Netgear has released a set of updated firmware for multiple devices to resolve a number of security vulnerabilities responsibly disclosed by researchers at Immersive Labs. These could lead to unauthorized access to devices or modification of the internal filesystem that can be abused to affect traffic passing through the device.

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.
