  • Report Again Finds US Government IT Security Sucks, Three Years After Saying The Same Thing

    Three years ago a US Senate Committee report showcased that the U.S. government's cybersecurity defenses were the IT equivalent of damp cardboard. The study found numerous government agencies were using dated systems that were expensive to maintain but hard to properly secure. It also noted how from 2008 to 2018, the government repeatedly failed to adequately protect sensitive data at the Social Security Administration and Departments of Homeland Security, State, Transportation, Housing and Urban Development, Agriculture, Health and Human Services, and Education.

  • Spam is Chipotle's secret ingredient: Marketing email hijacked to dish up malware

    Between July 13 and July 16, someone took over the Mailgun account owned by restaurant chain Chipotle Mexican Grill and placed an order for login credentials using misappropriated marketing messages.

    Phish-fighting firm INKY said on Thursday that it spotted 121 phishing emails during this period originating from Chipotle's Mailgun account.

    [...]

    But a sample Microsoft phishing message published by INKY suggests that inconsistency would not have been visible to recipients.

  • Apple Undermines Its Famous Security 'For The Children'

    Apple is somewhat famous for its approach to security on its iPhones. Most famously, Apple went to court to fight the FBI's demand that they effectively insert a backdoor into its on-phone encryption (by being able to force an update to the phone). Apple has tons of goodwill in the security community (and the public) because of that, though not in the law enforcement community. Unfortunately, it appears that Apple is throwing away much of that good will and has decided to undermine the security of its phone... "for the children" (of course).

  • SAML is insecure by design

    SAML uses signatures based on computed values. The practice is inherently insecure and thus SAML as a design is insecure.

  • HTTP/2: The Sequel is Always Worse

    HTTP/2 is easily mistaken for a transport-layer protocol that can be swapped in with zero security implications for the website behind it. In this paper, I'll introduce multiple new classes of HTTP/2-exclusive threats caused by both implementation flaws and RFC imperfections.

    I'll start by showing how these flaws enable HTTP/2-exclusive desync attacks, with case studies targeting high-profile websites powered by servers ranging from Amazon's Application Load Balancer to WAFs, CDNs, and bespoke stacks by big tech. These achieve critical impact by hijacking clients, poisoning caches, and stealing credentials to net multiple max-bounties.

    After that, I'll unveil novel techniques and tooling to crack open desync-powered request tunnelling - a widespread but overlooked request smuggling variant that is typically mistaken for a false positive. Finally, I'll share multiple new exploit-primitives introduced by HTTP/2, exposing fresh server-layer and application-layer attack surface.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
