  • No, the head of the World Health Organization has not emailed you – it's a message laced with malware

    As happens every time there is a major news event, scumbags exploit the public's interest to spread malware. This time, criminals have picked on the World Health Organization's handling of the global COVID-19 coronavirus pandemic. Researchers at IBM X-Force report the HawkEye malware is being spread under the guise of an email alert from WHO director general Tedros Adhanom Ghebreyesus.

    Victims are asked to open an attachment, launching the password-and-Bitcoin-harvesting Windows malware.

    "One thing worth mentioning is that the attackers put some effort in hiding the real intention of it," X-Force said. "The environmental awareness of our sample was quite good and average users would most likely not notice an info-stealer being installed."

  • Security 101: Virtual Private Networks (VPNs)

    I’m trying something new – a “Security 101” series. I hope to make these topics readable for those with no security background. I’m going to pick topics that are either related to my other posts (such as foundational knowledge) or just things that I think are relevant or misunderstood.

    Today, I want to cover Virtual Private Networks, commonly known as VPNs. First I want to talk about what they are and how they work, then about commercial VPN providers, and finally about common misconceptions.

  • Pwn2Own contest yields 13 bugs, as virtual format expands talent pool

    Research teams at the Pwn2Own 2020 competition successfully exploited 13 software vulnerabilities this past week, including bugs found in products from Adobe, Apple, Microsoft, Oracle and Ubuntu. Participants earned $270,000 over the two-day event — the first Pwn2Own ever to be held virtually, as a measure to combat the rapid spread of the novel coronavirus.

    Richard Zhu and Amat Cama of Fluoroacetate repeated from last year and were once again crowned Masters of Pwn. On day one, the team demonstrated a use-after-free (UAF) bug in Microsoft Windows and exploited it to escalate privileges to SYSTEM. The next day, they paired UAF bugs in Windows and Adobe Reader to once again elevate to SYSTEM.

    Other highlights included the chaining of six bugs to produce a macOS kernel escalation of privilege in Apple Safari, another Windows UAF flaw allowing the escalation of privileges to SYSTEM, a local privilege escalation in Ubuntu Desktop, and a two-bug combination in Oracle VirtualBox that enabled code execution on the host OS from the guest OS. Unofficially, the event also featured one additional flaw in VMware Workstation and another in Oracle VirtualBox, although they did not count toward the competition.

  • 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.
