  • Yet another Windows ransomware strain appears on the scene [iophk: Windows TCO]

    The global security firm Sophos said in a blog post that it had begun noticing the new Windows ransomware on 18 March as it took aim at Exchange boxes that still had not been patched to fix the ProxyLogon vulnerabilities disclosed by Microsoft on 3 March.

    Mark Loman, a director of Engineering for Next-Gen Technologies at Sophos, said the new ransomware did not have the most sophisticated of payloads.

  • Oil and gas company Shell suffers Accellion-related data breach

    Multinational oil and gas company Royal Dutch Shell plc is the latest victim of a data breach related to a vulnerability in software from Accellion Inc.

    In a statement last week, Shell said that the data security incident involved Accellion’s File Transfer Appliance that it uses to transfer large data files securely. The data accessed, during a “limited window of time” according to Shell, included some personal data along with data from Shell companies and some of their stakeholders. Shell noted that there is no evidence of any impact on their core information technology systems, since the fire transfer service is isolated from the rest of the company’s infrastructure.

  • Mimecast confirms [attackers] behind SolarWinds supply chain attack accessed limited amount of customer information
  • Continued Worsening of Ransomware [iophk: Windows TCO]

    Is there no solution? A means of detecting the patterns left by this kind of malware?

  • The Worsening State of Ransomware [iophk: Windows TCO]

    The problem is growing worse, despite the development of new and more advanced ways to battle it, including the use of behavioral analytics and artificial intelligence (AI). "Cybergangs use different cryptographic algorithms and they distribute software that is remarkably sophisticated and difficult to detect," Hinkley says. "Today, there is almost no barrier to entry and the damage that's inflicted is enormous."

  • Phish Leads to Breach at Calif. State Controller

    A phishing attack last week gave attackers access to email and files at the California State Controller’s Office (SCO), an agency responsible for handling more than $100 billion in public funds each year. The phishers had access for more than 24 hours, and sources tell KrebsOnSecurity the intruders used that time to steal Social Security numbers and sensitive files on thousands of state workers, and to send targeted phishing messages to at least 9,000 other workers and their contacts.

  • Spectre attacks against websites still a serious threat, Google warns

                     

                       

    Three years after the infamous Spectre vulnerability was discovered, [attackers] can still exploit the security flaw in order to force web browsers to leak information, Google’s security team warns.

                       

    The problem has arisen despite extensive efforts by browser developers to harden their software against Spectre-style attacks.

                       

    The results of the research was published on the Google Security Blog on Friday (March 12) and include a proof-of-concept exploit written in JavaScript that still works against several browsers, operating systems, and processors.

    The key lesson from the research is that Spectre still haunts the industry – so developers need to deploy application-level mitigation measures in order to guard against potential attacks.

  • 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.
