  • LoJax: First UEFI rootkit found in the wild, courtesy of the Sednit group

    UEFI rootkits are widely viewed as extremely dangerous tools for implementing cyberattacks, as they are hard to detect and able to survive security measures such as operating system reinstallation and even a hard disk replacement. Some UEFI rootkits have been presented as proofs of concept; some are known to be at the disposal of (at least some) governmental agencies. However, no UEFI rootkit has ever been detected in the wild – until we discovered a campaign by the Sednit APT group that successfully deployed a malicious UEFI module on a victim’s system.

  • Apple’s Device Enrollment Program Has A Security Flaw; Allows Hackers To Steal Company Passwords

    Researchers have found a security flaw in Apple’s Device Enrollment Program (DEP) that can allow an attacker to gain complete access to a corporate or school network.

  • MDM Me Maybe: Device Enrollment Program Security

    The Device Enrollment Program (DEP) is a service provided by Apple for bootstrapping Mobile Device Management (MDM) enrollment of iOS, macOS, and tvOS devices. DEP hosts an internet-facing API at https://iprofiles.apple.com, which - among other things - is used by the cloudconfigurationd daemon on macOS systems to request DEP Activation Records and query whether a given device is registered in DEP.

    In our research, we found that in order to retrieve the DEP profile for an Apple device, the DEP service only requires the device serial number to be supplied to an undocumented DEP API. Additionally, we developed a method to instrument the cloudconfigurationd daemon to inject Apple device serial numbers of our choosing into the request sent to the DEP API. This allowed us to retrieve data specific to the device associated with the supplied serial number.

  • ARMv8.5-A Support Being Prepped To Battle Spectre-Style Vulnerabilities

    Earlier this month Arm began publishing details of the ARMv8.5-A instruction set update, which is expected to be officially documented and released by the end of Q1'2019, while the LLVM compiler stack has already received initial support for the interesting additions.

  • 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.
