  • Reproducible Builds (diffoscope): diffoscope 186 released

    The diffoscope maintainers are pleased to announce the release of diffoscope version 186. This version includes the following changes:

    [ Chris Lamb ]
    * Don't call close_archive when garbage-collecting Archive instances unless
      open_archive returned successfully. This prevents, amongst others, an
      AttributeError traceback due to PGPContainer's cleanup routines assuming
      that its temporary directory had been created.
      (Closes: reproducible-builds/diffoscope#276)
    * Ensure that the string "RPM archives" exists in the package description,
      regardless of whether python3-rpm is installed or not at build time.
    
    [ Jean-Romain Garnier ]
    * Fix the LVM Macho comparator for non-x86-64 architectures.
    
  • Crashes in OpenBSD, DragonFly BSD and Electron due to deprecation of the IdenTrust root certificate

    The termination of the IdenTrust root certificate (DST Root CA X3) used to cross-sign the Let’s Encrypt CA root certificate resulted in problems with Let’s Encrypt certificate validation in projects using older versions of OpenSSL and GnuTLS. Problems also affected the LibreSSL library, the developers of which did not take into account past experience related to failures that occurred after the AddTrust root certificate of the Sectigo (Comodo) certification authority expired.

    Recall that in releases of OpenSSL up to and including the 1.0.2 branch and in GnuTLS before release 3.6.14 , there was an error that did not allow the correct processing of cross-signed certificates, if one of the root certificates used for signing expired, even if other valid ones were saved. chains of trust (in the case of Let’s Encrypt, the aging of the IdenTrust root certificate does not allow verification, even if the system supports its own Let’s Encrypt root certificate valid until 2030). The essence of the error is that older versions of OpenSSL and GnuTLS parsed the certificate as a linear chain, while according to RFC 4158, a certificate can represent a directed distributed circular graph with several trust anchors that need to be considered.

  • BloodHound – Hacking Active Directory Trust Relationships

    Attackers can use BloodHound to easily identify highly complex attack paths that would otherwise be impossible to quickly identify. Defenders can use it to identify and eliminate those same attack paths. Both blue and red teams can use BloodHound to easily gain a deeper understanding of privilege relationships in an Active Directory environment.

    It is a single page JavaScript web application, built on top of Linkurious, compiled with Electron, with a Neo4j database fed by a PowerShell ingestor.

  • Getting Started With Kali

    Kali is a Debian based distribution aimed at penetration testing. I haven’t felt a need to use it in the past because Debian has packages for all the scanning tools I regularly use, and all the rest are free software that can be obtained separately. But I recently decided to try it.

    Here’s the URL to get Kali [1]. For a VM you can get VMWare or VirtualBox images, I chose VMWare as it’s the most popular image format and also a much smaller download (2.7G vs 4G). For unknown reasons the torrent for it didn’t work (might be a problem with my torrent client). The download link for it was extremely slow in Australia, so I downloaded it to a system in Germany and then copied it from there.

    [...]

    Installing VMs for both these distributions was quite easy. Most of my time was spent downloading from a slow server, trying to get SCSI emulation working, working out how to convert image files, and testing different compression options. The time spent doing stuff once I knew what to do was very small.

  • 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.
