    Microsoft has acknowledged a newly-discovered version of an attack on a long-vulnerable Windows single sign-on protocol called NTLM — short for New Technology LAN Manager — that is still used in the operating system as a backup to the newer Kerberos authentication protocol.

  • PlugwalkJoe Does the Perp Walk

    One day after last summer’s mass-hack of Twitter, KrebsOnSecurity wrote that 22-year-old British citizen Joseph “PlugwalkJoe” O’Connor appeared to have been involved in the incident. When the U.S. Justice Department last week announced O’Connor’s arrest and indictment, his alleged role in the Twitter compromise was well covered in the media.

  • ‘Holy moly!’: Inside Texas’ fight against a ransomware hack [iophk: Windows TCO]

    Texas communities struggled for days with disruptions to core government services as workers in small cities and towns endured a cascade of frustrations brought on by the sophisticated cyberattack, according to thousands of pages of documents reviewed by The Associated Press and interviews with people involved in the response. The AP also learned new details about the attack’s scope and victims, including an Air Force base where access to a law enforcement database was interrupted, and a city forced to operate its water-supply system manually.

  • Chat logs show how Egregor, an $80 million ransomware gang, handled negotiations with little mercy [iophk: Windows TCO]

    Egregor has since disappeared, following an international sting in February. Now, though, more than 100 pages of Egregor negotiation transcripts — obtained and analyzed by IBM Security X-Force and its partner company Cylera, and reviewed by CyberScoop — shed light on the oft-opaque structure of a ransomware operation. The discussion records also demonstrate how victims proved most effective at convincing their extortionists to reduce the amount demanded to decrypt their systems, with one medical organization turning a $15 million ransom into a $2 million payment.

  • Paul E. Mc Kenney: Confessions of a Recovering Proprietary Programmer, Part XVIII: Preventing Involuntary Generosity

    I recently learned that all that is required for someone to take out a loan in some random USA citizen's name is that citizen's full name, postal address, email address, date of birth, and social security number. If you are above a certain age, all of these are for all intents and purposes a matter of public record. If you are younger, then your social security number is of course supposed to be secret—and it will be, right up to that data breach that makes it available to all the wrong people.

    This sort of thing can of course be a bit annoying to our involuntarily generous USA citizen. Fortunately, there are quite a few things you can do, although I will not try to reproduce the entirety of the volumes of good advice that are available out there. Especially given that laws, processes, and procedures are all subject to change.

  • Dead Drops and Security Through Obscurity

    There’s massive confusion in the security community around Security Through Obscurity.

    In general, most people know it’s bad, but they can’t say exactly why. And because of this, people tend to think the “Obscurity” in “Security Through Obscurity” equates to secrecy, meaning if you hide anything, it’s Security Through Obscurity.

    This is incorrect, and Dead Drops are a great example.

  • Preventing Data Exfiltration with eBPF

    Consider a service invoking webhooks. It will be running with limited data access but must be able to communicate with the entire Internet. Contrast that to an SSH session that’s been opened for troubleshooting purposes. It will have access to the entire machine but does not egress to an arbitrary IP.

  • 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.
