Microsoft to upgrade Windows Subsystem for Linux (WSL) with faster file access, better networking and easier setup

Microsoft plans to enhance the Windows Subsystem for Linux (WSL) in 2026, focusing on several key improvements for developers. These enhancements include: - Faster file performance between Linux and Windows to address current latency issues. - Improved network compatibility and throughput for better communication between environments. - A streamlined setup and onboarding experience to simplify installation for newcomers. - Enhanced enterprise management and security features to improve control and safety in corporate settings.

Fake Cloudflare CAPTCHA Pages Spread Infiniti Stealer On macOS

Security researchers have identified a new macOS information stealer called Infiniti Stealer, which extracts sensitive information from Mac users using a social engineering tactic known as ClickFix. This method involves a counterfeit Cloudflare human verification page that prompts users to enter a command in their Mac Terminal, allowing the malware to bypass security measures. The infection process consists of three stages: 1. A Bash dropper script downloads and decodes a hidden payload. 2. A Nuitka loader, designed for Apple Silicon Macs, complicates detection by compiling Python code into a native application. 3. The final payload, Infiniti Stealer, harvests personal data such as browser passwords, macOS Keychain entries, cryptocurrency wallets, and captures screenshots. Indicators of Compromise (IOCs) associated with Infiniti Stealer include: - MD5 Dropper: da73e42d1f9746065f061a6e85e28f0c - SHA256 Stage-3: 1e63be724bf651bb17bcf181d11bacfabef6a6360dcdfda945d6389e80f2b958 - C2 Domain: update-check[.]com - C2 URL: https://update-check[.]com/m/7d8df27d95d9 - Panel: Infiniti-stealer[.]com - Packer Magic: 4b 41 59 28 b5 2f fd (KAY + zstd) - Debug Log: /tmp/.bs_debug.log

These 4 open-source apps fixed Windows’ biggest problems

Windows operating system has evolved over the years, but initially, it often required external tools for tasks like video playback, file compression, secure connections, and file transfers. VLC Media Player addressed the issue of codec compatibility in video playback by bundling its own codecs, making it a widely used media player. 7-Zip improved file compression on Windows by offering superior efficiency, extensive format support, and user-friendly features, becoming essential for archiving tasks. PuTTY provided Windows users with their first effective SSH client, allowing secure terminal connections to remote servers, and remains popular despite Microsoft integrating OpenSSH. FileZilla simplified the process of uploading files to servers with its user-friendly graphical interface, becoming a staple for web developers. Despite improvements in Windows, many users continue to install these open-source applications out of habit due to their reliability and effectiveness.

Hackers hijacked antivirus features to install malware – here’s what we know

A critical vulnerability identified as CVE-2025-12480 was found in the remote file sharing platform Triofox, characterized by improper access control that allowed zero-day exploitation. Security experts from Google’s Mandiant revealed that Triofox's antivirus feature was compromised, enabling unauthorized access to setup pages post-installation. The UNC6485 threat group exploited this vulnerability using tools like Zoho Assist, AnyDesk, and SSH tunneling for remote access. A patch was released on July 26, and a newer version of Triofox was made available on October 14 to mitigate the risks, with users advised to update their systems.

Russian APT abuses Windows Hyper-V for persistence and malware execution

Cyber attackers used the Import-VM and Start-VM PowerShell cmdlets to introduce a virtual machine named WSL into Hyper-V. This virtual machine hosts a compact Alpine Linux environment with two implants, CurlyShell and CurlCat, identified by Bitdefender. CurlyShell uses libcurl to connect to a command-and-control server, creating a reverse shell to execute commands and return outputs. CurlCat functions as a proxy, tunneling SSH traffic through HTTP requests to evade detection by network monitoring tools.

Hackers Are Using Linux Malware to Invisibly Bypass Windows Security

Hackers are refining tactics to evade detection by EDR systems and antivirus software, with a notable strategy being the use of Linux malware to infiltrate Windows systems. Investigations by Bitdefender and CERT-GE revealed a campaign by the Russian hacker group Curly COMrades, which exploits the Hyper-V virtualization platform on Windows 10 to create covert access channels. They utilize Alpine Linux for lightweight virtual machines that are difficult to detect, requiring only 120 MB of disk space and 256 MB of RAM. The attackers maintain persistent access using tools like Resocks and Stunnel, starting their activities in early July 2024 by activating Hyper-V on compromised systems and deploying misleading virtual machines labeled “WSL.” They introduced custom malware, CurlyShell and CurlCat, for communication and remote access. This trend of using Linux malware against Windows systems is growing, as seen in recent Qilin ransomware attacks documented by Trend Micro.
