  • VMware patches critical guest-to-host vulnerabilities [Ed: The security problem is VMware, not Linux]

    In an advisory this week, VMware alerted users to guest-to-host vulnerabilities in the XHCI and UHCI USB controllers in its ESXi hypervisor, plus an important flaw fixed in NSX Data Center for vSphere.

    In all, five vulnerabilities were discovered in VMware's ESXi, Workstation, Cloud Foundation (ESXi), and Fusion during the Tianfu Cup 2021, a Chinese vulnerability competition, by the country's Kunlun Lab. Bugs that Kunlun discovered were disclosed privately to VMware – though last year China passed a new law ordering security researchers to reveal findings to the country's Ministry of Public Security at least two days before anyone else.

    The vendor said it hadn't seen any evidence the competition's findings had been exploited in the wild. Patches have been issued, now it's up to admins to schedule them. The vulnerabilities range from use-after-free() and double-fetch flaws that can be exploited to execute code on the host, to an old-fashioned denial of service (DoS).

  • US, Allies Warn Possible Russian Cyberattacks Could Reverberate Globally [iophk: Windows TCO]

    "It's not hypothetical," Monaco said, pointing to the June 2017 "NotPetya" virus, engineered by Russia's military intelligence service, the GRU.

    The virus initially targeted a Ukrainian accounting website but went on to hobble companies around the world, including Danish shipping giant Maersk and U.S.-based FedyEx.

    "Companies of any size and of all sizes would be foolish not to be preparing right now," Monaco said. "They need to be shields-up and really be on the most heightened level of alert."

  • As Russia amasses troops, Ukraine battles another threat: Digital warfare [iophk: Windows TCO]

    A new wave of cyber operations began in earnest Jan. 13, when computers in Ukraine started showing signs of the first serious hacking campaign since Russia’s troop buildup. Computers at dozens of Ukrainian organizations, including nonprofit groups, information technology companies and more than 70 government websites, were infected with malicious software that appeared to be ransomware, a common criminal tactic to lock up computers.

  • US says Russian [crackers] targeted defense contractors [iophk: Windows TCO]

    The U.S. intelligence community says that Russian-sponsored actors have been targeting defense contractors for at least the past two years and in some cases have gained access to sensitive information.

    In an alert released Wednesday, the FBI, National Security Agency (NSA) and Cybersecurity and Infrastructure Security Agency (CISA) said they had observed “regular targeting” of contractors from at least January 2020 through this month.

  • Civil society calls for solidarity with Ukraine’s human rights defenders in guarding against cyber threats

    In a statement issued today, Access Now, together with Centre for Democracy and Rule of Law and Digital Security Lab Ukraine, calls on the international community to take swift action in support of civil society in Ukraine, as well as the broader public whose human rights are being undermined by cyberattacks on Ukraine’s critical infrastructure.

    Following the most recent cyberattacks on January 13-14 and February 15, 2022 targeting Ukraine’s essential public service infrastructure, and the ongoing threat of escalating Russian aggression, this is a critical moment for solidarity with Ukrainian civil society.

  • ttacks on Ukraine’s infrastructure and civil society violate human rights

    There is a pressing need to provide Ukrainian civil society with technical means to protect both themselves and the sensitive data on their servers and devices, as well as to prevent future attacks. We urge tech companies, nonprofits, and funders to expand their support programs and provide Ukrainian activists with free and secure VPNs, antivirus programs, encryption, DDoS protection, and other essential digital tools, equipment, and services.

  • 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.
