Security and Proprietary Software

  • Complete Guide to Installing Security Updates in Debian & Ubuntu

    Whether you are a DevSecOps engineer responsible for managing your organization’s application infrastructure or you have your own personal Linux server that you use at home, the importance of keeping your systems safe and secure against malicious attacks by bad actors cannot be over emphasized.

    While there are many aspects with regards to securing systems, one fundamental best practice is to continuously patch your systems and applications as soon as they are made available. The infamous WannaCry ransomware attack from the summer of 2017, that caused much grief to millions of users is a case in point. While the patch was made available much ahead of the actual attack, it was due to a sheer lack of security discipline that the attack was successful.

  • SolarWinds issues software update – one it wrote for a change – to patch hole exploited in the wild

    SolarWinds has issued an emergency patch after a critical security hole in its Serv-U Managed File Transfer and Serv-U Secure FTP was spotted being exploited in the wild.

    The vulnerability, discovered by Microsoft's Threat Intelligence Center (MSTIC) and Offensive Security Research teams, can be exploited by an attacker to achieve remote code execution, and is present in Serv-U version 15.2.3 HF1 and all prior builds. The Redmond crew also said a "single threat actor" was abusing the programming blunder (CVE-2021-35211) though it's not known how many customers are affected.

    "This attack is a Return Oriented Programming (ROP) attack," said SolarWinds in an advisory. "When exploited, the vulnerability causes the Serv-U product to throw an exception and then intercepts the exception handling code to run commands. Please note, several reasons exist for exceptions to be thrown, so an exception itself is not necessarily an indicator of attack."

  • With a straight face, Putin agrees to do something about ransomware coming out of Russia, apparently [Ed: Distraction and deflection from Microsoft back doors and insecurity by design]

    ate last week, President Biden said he brought up the epidemic of ransomware hitting American businesses in a phone call with his Russian counterpart, and hinted America may start hitting back.

    Biden said he and Vladimir Putin not only discussed the matter, their two countries are apparently going to try to coordinate some action to tackle the waves of extortionware infections, which seem to be mainly orchestrated by miscreants in Russia and typically avoid compromising computers configured to use the Russian language.

    IT management software made by Kaseya was lately exploited to install REvil ransomware on as many as 1,500 businesses. The crew behind that software nasty is said to avoid targeting Russian organizations.

  • Ransomware Attacks Hit Closer To Home

    Fifteen hundred organizations around the world had their data locked up in the latest ransomware, including grocery store chains and schools. It’s unclear if any IBM i shops were included in the attack, which a Russian hacking group claimed credit for. But it’s clear that ransomware is a growing threat to all organizations, including IBM i shops.

  • Microsoft broke British and European competition laws, UK reseller tells High Court

    Microsoft's attempts to kill off resellable perpetual software licences infringe the EU constitution and UK competition law alike, according to the legal filings of a reseller suing Redmond for £270m in London's High Court.

  • 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.
