New XZ Backdoor Scanner Detects Implants In Any Linux Binary

Bill Toulas reports via BleepingComputer: Firmware security firm Binarly has released a free online scanner to detect Linux executables impacted by the XZ Utils supply chain attack, tracked as CVE-2024-3094. CVE-2024-3094 is a supply chain compromise in XZ Utils, a set of data compression tools and libraries used in many major Linux distributions. Late last month, Microsoft engineer Andres Freud discovered the backdoor in the latest version of the XZ Utils package while investigating unusually slow SSH logins on Debian Sid, a rolling release of the Linux distribution. The backdoor was introduced by a pseudonymous contributor to XZ version 5.6.0, which remained present in 5.6.1. However, only a few Linux distributions and versions following a "bleeding edge" upgrading approach were impacted, with most using an earlier, safe library version. Following the discovery of the backdoor, a detection and remediation effort was started, with CISA proposing downgrading the XZ Utils 5.4.6 Stable and hunting for and reporting any malicious activity. Binarly says the approach taken so far in the threat mitigation efforts relies on simple checks such as byte string matching, file hash blocklisting, and YARA rules, which could lead to false positives. This approach can trigger significant alert fatigue and doesn't help detect similar backdoors on other projects. To address this problem, Binarly developed a dedicated scanner that would work for the particular library and any file carrying the same backdoor. [...] Binarly's scanner increases detection as it scans for various supply chain points beyond just the XZ Utils project, and the results are of much higher confidence. Binarly has made a free API available to accomodate bulk scans, too.

Best Practices and Strategic Insights to Dockerizing Your Linux Applications

In the realm of software development and deployment, Docker has emerged as a revolutionary force, offering a streamlined approach to creating, deploying, and running applications by using containers. Containers allow developers to package up an application with all the parts it needs, such as libraries and other dependencies, and ship it all out as one package. This guide delves deep into the world of Dockerizing applications on Linux, covering best practices, deployment strategies, and much more to empower developers and DevOps professionals alike.

Understanding Docker and Containerization

Docker is a platform that utilizes OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels. Unlike traditional virtual machines, containers do not bundle a full operating system — just the application and its dependencies. This makes them incredibly lightweight and efficient.

The Benefits of Docker

Consistency across Environments: Docker containers ensure that applications work seamlessly in any environment, from a developer's personal laptop to the production server.
Isolation: Applications in Docker containers run in isolated environments, reducing conflicts between applications and between applications and the host system.
Resource Efficiency: Containers share the host system kernel and start much faster than VMs. They also require less compute and memory resources.
Scalability and Modularity: Docker makes it easy to break down applications into microservices, making them easier to scale and update.

Setting Up Docker on Linux

The process to install Docker varies depending on the Linux distribution. For Ubuntu, for instance, Docker can be installed with just a few commands:

sudo apt update sudo apt install docker.io sudo systemctl start docker sudo systemctl enable docker

After installation, verify that Docker is running by executing sudo docker run hello-world. This command pulls a test image from Docker Hub and runs it in a container, which prints a message.

Dockerizing Applications: Best Practices

Creating Efficient Dockerfiles

A Dockerfile is a script containing a series of commands and instructions to build a Docker image. The key to an efficient Dockerfile is minimizing the build time and the size of the image.

"What a time we live in," writes Phoronix, "where Microsoft not only continues contributing significantly to the Linux kernel but doing so to further flesh out the design of the Linux kernel's Rust programming language support..." Microsoft engineer Wedson Almeida Filho has sent out the latest patches working on Allocation APIs for the Rust Linux kernel code and also in leveraging those proposed APIs [as] a means of allowing in-place module initialization for Rust kernel modules. Wedson Almeida Filho has been a longtime Rust for Linux contributor going back to his Google engineering days and at Microsoft the past two years has shown no signs of slowing down on the Rust for Linux activities... The Rust for Linux kernel effort remains a very vibrant effort with a wide variety of organizations contributing, even Microsoft engineers.
