  • 6 top OSINT tools: Find sensitive public info before hackers do

    The same OSINT tactics used for spycraft can now be applied to cybersecurity. Most organizations have vast, public-facing infrastructures that span many networks, technologies, hosting services and namespaces. Information can be stored on employee desktops, in legacy on-prem servers, with employee-owned BYOD devices, in the cloud, embedded inside devices like webcams, or even hidden in the source code of active apps and programs.

  • 3 steps toward improving container security

    As developers increasingly make use of containers, securing them becomes more and more important. Gartner has named container security one of its top 10 concerns for this year in this report, which isn’t surprising given their popularity in producing lightweight and reusable code and lowering app dev costs.

    In this article, I’ll look at the three basic steps involved in container security: securing the build environment, securing the underlying container hosts, and securing the actual content that runs inside each container. To be successful at mastering container security means paying attention to all three of these elements.

    If you step back a moment, container security isn’t all that different from ordinary application security. If you replace the appropriate words in the above paragraph, you could have written this post 10, 20, or even 30 years ago with a few other modifications. But containers do have a few oddities and new twists that are worth highlighting. To get started, I suggest you listen to the recorded talk by Red Hat’s Dan Walsh about general container security considerations.

  • Good guy, Microsoft: Multi-factor auth outage gives cloudy Office, Azure users a surprise three-day weekend

    Microsoft is battling to fix its knackered multi-factor authentication system that today blocked customers from logging into their Microsoft 365 and Azure services.

    The Redmond giant confirmed on Friday an unspecified glitch prevented customers in North America from receiving the multi-factor auth (MFA) codes they need to sign into their cloud-based accounts. Obviously, those not using MFA are not affected.

    Though Azure and Microsoft 365 MFA users initially were locked out, by mid-day US Pacific Time, Azure was said to be working again, leaving 365 subscribers trying to log in high and dry.

    "We've taken multiple actions to mitigate impact and are working to validate service restoration," Microsoft told Microsoft 365 aka Office 365 customers. "In parallel, we're continuing to review system logs and service telemetry to better understand the underlying root cause."

  • Update Warning Issued For Millions Of Microsoft Windows 10 Users

    At this stage, it isn’t clear what is the cause with users citing BSOD failures with cldflt.sys, Affinity applications and more but all have found that uninstalling KB4517389 fixes the problem, which pins the source squarely on this already troubled update. Needless to say, the problem with a BSOD bug is you may not be lucky enough to get back to your desktop to do this.

    If you are, then navigate to Control Panel > Programs > Programs and Features > Installed updates > KB4517389 > Uninstall

    KB4517389 has already rolled out to millions of users but for hundreds of millions who have not received it yet, use Microsoft’s Show or Hide updates tool to block it from installing on your PC.

  • 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.
