  • Attacks on Kaseya Servers Led to Ransomware in Less Than 2 Hours

    At 4:30 p.m. UTC, all within the same second, the compromised servers woke up and ran a command script that disabled a variety of security controls and sent malicious payloads to every system managed by those servers, according to an analysis conducted by Huntress Labs. While security firms are still sifting through the data, reverse engineering has revealed that the attack — from the first packets exploiting dozens of VSA servers, to the deployment of ransomware on the endpoints of hundreds to thousands of MSP customers — took less than two hours.

    The speed of automation gave managed service providers and their customers only a very narrow window in which to detect attacks and block them, says John Hammond, a senior threat researcher for Huntress Labs. Companies would have to run frequent monitoring and alerts to have caught the changes, he says.

    "Unfortunately, this form of hyperactive logging and detection is rare — managed service providers often don't have the resources, let alone the personnel to frequently monitor massive components of their software and stack," Hammond says. "With that said, the efficacy and potential for human-powered threat hunters is never something to be left out of the equation."

    The quick turnaround of the attack underscores the compressed timeline for defenders to respond to automated attacks. The REvil group and its affiliates, who are thought responsible for the attack, scanned for Internet-connected VSA servers and, when found, sent the initial exploit, which chained three vulnerabilities.

  • Jack Cable, Stanford student and cyber whiz, aims to crowdsource ransomware details

    Few people, if any, seem to grasp the breadth and cost of the scourge, as there are no legal requirements for victims to disclose when they pay hackers to unlock their network. That, combined with the suspicious that most victims don’t, report their digital extortion payments, makes it harder for law enforcement and security firms to combat attacks, or even understand how to fight them.

    That’s the impetus behind a project that Stanford University student and security researcher Jack Cable launched on Thursday, dubbed “Ransomwhere,” a plan to track payments to bitcoin addresses associated with known ransomware gangs.

  • DoD ends $10 billion deal with Microsoft for new cloud contract

    The statement did not directly mention that the Pentagon faced extended legal challenges by Amazon to the original $1 million contract awarded to Microsoft. Amazon argued that the Microsoft award was tainted by politics, particularly then-President Donald Trump’s antagonism toward Amazon founder, Jeff Bezos, who stepped down Monday as the company’s chief executive officer. Mr. Bezos owns The Washington Post, a newspaper often criticized by Mr. Trump.

    The Pentagon’s chief information officer, John Sherman, told reporters Tuesday that during the lengthy legal fight with Amazon, “the landscape has evolved” with new possibilities for large-scale cloud computing services. Thus it was decided, he said, to start over and seek multiple vendors.

  • With ransomware attacks multiplying, US moves to bolster defenses

    As the U.S. private sector scrambles to fend off a growing number of ransomware attacks, the federal government is stepping up its efforts as well. Last month, the Senate approved Chris Inglis, a former deputy director of the National Security Agency, as the nation’s first-ever national cyber director, tasked with coordinating the government’s cyber portfolio and digital defense strategy. A second key post, director of the primary domestic cybersecurity agency, is expected to be filled shortly.

    Officials are making clear they will seek not just to hold cybercriminals to account – but also companies whose inadequate cybersecurity measures have put them and their customers at risk.

  • 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.
