Microsoft denies WSL 3 exists, reveals Windows 11’s WSL Containers ship next week

Microsoft has clarified that there is no WSL 3 in development, as stated by Craig Loewen, the Product Manager for the Windows Subsystem for Linux (WSL). The confusion arose from articles discussing a new feature called WSL Containers, which will be launched soon. WSL allows users to run Linux environments on Windows without dual-booting, while WSL Containers enable the creation and management of Linux containers directly within Windows, eliminating the need for third-party tools like Docker Desktop. WSL 1, introduced in 2016, served as a translation layer for Linux system calls, and WSL 2, launched in 2019, included a full Linux kernel in a lightweight virtual machine. WSL Containers is an enhancement to WSL, allowing developers to build, run, and deploy containers directly from Windows using the wslc.exe command. This feature is part of Microsoft's strategy to make Windows a more accessible platform for running Linux workloads, helping to retain developers who might consider switching to other operating systems.

Windows RAT Uses Encrypted HTTP C2 and Registry Persistence After npm Infection

A malware campaign targets Windows systems through a malicious npm package named postcss-minify-selector-parser, which mimics the legitimate postcss-selector-parser. This counterfeit package installs a Remote Access Trojan (RAT) on developer machines, beginning with a multi-stage attack triggered by the installation of the package. The RAT can steal credentials, execute shell commands, and communicate with a remote attacker. Security researchers at JFrog identified this threat and reported it on June 22, 2026, noting that two additional related packages, postcss-minify-selector and aes-decode-runner-pro, are linked to the same publisher and remain live on the npm registry. The RAT employs encrypted HTTP communication with a command-and-control (C2) server and ensures persistence by creating a registry key under the Windows Run key. It has capabilities for remote shell execution, file uploads and downloads, and can steal saved login data from Google Chrome using Windows decryption APIs. The malware is designed for organized batch exfiltration of stolen data. Indicators of compromise include specific IP addresses, domains, file paths, and SHA-256 hashes associated with the malware components. JFrog advises users to remove the malicious packages, inspect their dependency trees, and treat any stored credentials as compromised.

Why Oracle’s OCI Database with PostgreSQL matters for serious workloads

Oracle has launched the OCI Database with PostgreSQL, a managed PostgreSQL service designed for seamless deployment within the Oracle Cloud. This service includes lifecycle management, automated backups, and monitoring, allowing users to customize their database configurations easily. A key feature is the cross-region warm standby, which enhances disaster recovery by enabling users to create replica databases in secondary regions that replicate data from the primary database. The service enforces a strict 5-minute recovery point objective (RPO) and simplifies the setup process for operations teams. The OCI Database with PostgreSQL is positioned against offerings from AWS and Azure, targeting organizations that prefer a managed PostgreSQL experience. However, compliance challenges, such as the lack of FedRAMP certification, may hinder adoption for certain sectors. The product is available on OCI with usage-based pricing and is aimed at cloud teams needing managed operations and disaster recovery for PostgreSQL databases.

A Brief History Of Unix Commands On Windows: CoreUtils (Again)

The interaction between Unix/Linux and Windows has historically been marked by significant differences in their architectures and philosophies. Unix uses a fork() function for process management, while Windows employs CreateProcess(), complicating the implementation of Unix-like tools on Windows. Early solutions to bridge this gap included the MKS Toolkit, which provided Unix-like commands for Windows, and UWIN from AT&T Bell Labs, which aimed to create a Unix interface layer on Windows. Cygwin offered a compatibility DLL to run Unix software on Windows, but required rebuilding from source. Microsoft's initiatives included POSIX, Interix, and later Services for UNIX. The introduction of the Windows Subsystem for Linux (WSL) allowed users to run a Linux userland directly on Windows, with WSL 2 incorporating a real Linux kernel. Recently, Microsoft released Coreutils for Windows, providing native builds of Unix-style tools to enhance cross-platform consistency.

Microsoft released the Windows 11 Secure Boot update for all PCs, how to verify yours

Microsoft has expanded the rollout of the Secure Boot 2023 certificate update to more Windows 11 and Windows 10 devices with the June 2026 Patch Tuesday update (KB5094126). This update aims to ensure that most supported consumer PCs are classified as high confidence, meaning necessary certificates are either installed or will be applied automatically. Secure Boot is a firmware security feature that verifies the software attempting to load during the startup process, blocking unauthorized software. The certificates supporting Secure Boot, issued in 2011, are expiring in stages starting June 24, 2026, prompting Microsoft to deploy replacement certificates. Most home users do not need to take manual action as the updates will occur automatically via Windows Update. Users can check their Secure Boot certificate status in the Windows Security app. A yellow warning indicates pending compatibility data, while a red alert suggests a firmware incompatibility requiring a BIOS update. Multiple reboots during the update process are normal, and a new SecureBoot folder in Windows is for staging cryptographic files. Older PCs may experience longer update times, and some may not receive updates due to firmware issues. HP users should check for BIOS updates if encountering BitLocker recovery loops. IT administrators should monitor device classifications and manually initiate updates for devices not in the high confidence category. Devices with Secure Boot disabled cannot receive updates, leaving them vulnerable. The expiration of the Microsoft Corporation KEK CA 2011 certificate on June 24 does not immediately affect device functionality, but it limits Microsoft's ability to sign new bootkit blacklist updates.

Торрент-стриминг без вреда для SSD: переносим TorrServer в Proxmox LXC и интегрируем с Lampa

Modern budget Smart TVs, like the Xiaomi Mi TV, often have limited processing power and memory (1 to 1.5 GB of RAM), which can lead to performance issues when running applications like TorrServer. Users may experience network overloads due to extensive communication with the torrent network, resulting in dropped streams and network failures. Additionally, the RAM shortage can cause the Android system to terminate background services or crash due to Out of Memory errors. CPU throttling occurs as the CPU struggles with torrent processing, leading to overheating and poor playback quality. To address these issues, it is recommended to run TorrServer on a dedicated home server instead of the TV. A lightweight Debian 12 LXC container can be deployed on a Proxmox VE host for this purpose, with the following specifications: VMID 212, hostname torrserver, 2 CPU cores, 2 GB RAM, 512 MB swap, and 8 GB disk space. The container can be created using a specific command on the Proxmox host, and after creation, the TorrServer application can be installed and configured to start automatically.

Use Windows Sandbox and containers to test untrusted apps safely

Windows 11 features Smart App Control to block untrusted applications and includes Windows Sandbox, a lightweight virtual machine that provides an isolated desktop environment for safely executing applications. Windows Sandbox uses container technology and hypervisor-based virtualization to mitigate risks associated with untrusted software. It ensures that each session starts fresh, with no data persisting after closing, and applications installed on the host system are not accessible within the Sandbox. Starting with Windows 11 version 22H2, data can persist through restarts initiated within the Sandbox. Windows Sandbox is included in supported Windows editions such as Pro, Enterprise, and Education, and offers quick launch times, a lower memory footprint, and a secure environment for testing untrusted software. Setting up Windows Sandbox involves searching for it in the Start menu, running it as an administrator, and transferring executable files for installation within the Sandbox.
