  • Microsoft struggles to wake from its PrintNightmare: Latest print spooler patch can be bypassed, researchers say

    Any celebrations that Microsoft's out-of-band patch had put a stop PrintNightmare shenanigans may have been premature.

    The emergency update turned up yesterday for a variety of Microsoft operating systems; little-used products like Windows Server 2012 and 2016 were excluded from the interim release.

    While it initially appeared the remote-code execution (RCE) aspect of the security bug had been resolved, the local privilege escalation (LPE) hole remained, judging by the findings of a number of security researchers.

  • Microsoft patches PrintNightmare – even on Windows 7 – but the terror isn't over

    Microsoft has issued out-of-band patches for the PrintNightmare bug that allows remote and local Windows users to execute code as SYSTEM on boxes running the print spooler service, including domain controllers.

    The bug, designated CVE-2021-34527, is present in all versions of Windows.

    However, Microsoft's advisory states: "Updates are not yet available for Windows 10 version 1607, Windows Server 2016, or Windows Server 2012."

  • Kaseya’s VSA SaaS restart fails, service restoration delayed by at least ten hours

    Kaseya’s attempt to recover its SaaS services has failed, and its CEO has attempted to play down the significance of the incident that has seen its VSA services offline since July 2nd and over 1,000 ransomware infections.

    [...]

    The company had previously advised that SaaS restoration had commenced, with individual SaaS servers due to come online “throughout the night US time”. “All systems will be online and accessible by July 7th 6AM US EDT,” the advice stated.

    Now the company says its next update will come at 8AM US EDT. It has offered no information on likely time of restoration or the nature of the issue that has slowed the SaaS rollout. Nor has Kaseya said if its promise to patch its on-premises VSA software within 24 hours of SaaS restoration remains in force.

  • The 10 best books on computer security | FOSS Linux

    The term computer security is also synonymous with Cybersecurity and information technology security. It relates to protecting, preventing, and understanding the threats that can cause harm to both a networked computer system and a configured information system. The security threat can result from the theft of data on such systems or their unauthorized use.

    A computer system is defined by both hardware and software. Since computer hardware is also equally valuable, the protection of sensitive computer hardware parts is easily achievable through alarms, locks, and serial numbers. On the other hand, achieving data protection and authenticated system access is not straightforward. It requires complex security tactics and algorithms.

  • 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.
