Threat actors are exploiting Windows Remote Management (WinRM) to navigate through Active Directory environments stealthily, allowing them to bypass detection systems, escalate privileges, and deploy malicious payloads. WinRM operates on HTTP port 5985 and HTTPS port 5986, enabling remote command execution and management tasks. Attackers can gain access through compromised credentials and use WinRM-enabled PowerShell commands for reconnaissance, deploying payloads while evading detection. The attack chain includes initial access, reconnaissance, payload deployment, persistence, and lateral movement, often utilizing techniques that obfuscate malicious activities. Detecting such attacks is challenging due to the use of built-in Windows functionalities and encrypted channels. Recommended mitigation strategies include monitoring for unusual activity, restricting WinRM access, enforcing credential hygiene, and implementing advanced monitoring solutions.

Antivirus software collects various types of data to protect systems, including system details (operating system version, RAM, CPU type, computer name), network data (local and external IP addresses, DNS server, network name), user data (Windows username, time zone, language, general location), browsing history (if web protection features are enabled), and file-related information (file names, locations, hashes, and sometimes entire files). The AV-Comparatives report indicates that while some antivirus companies manage data responsibly (e.g., F-Secure, G Data, K7), others (e.g., Norton, Panda, McAfee) have been criticized for poor practices. Data sharing can enhance malware detection but poses privacy risks, as seen in AVG's past actions of selling user browsing history. Users can limit data collection by adjusting settings, reviewing installation agreements, avoiding free antivirus software, choosing privacy-conscious vendors (like F-Secure, ESET, G Data), and reading privacy policies. Despite concerns about data collection, antivirus software is essential for protection against cyber threats, and selecting a transparent provider can help safeguard privacy.

Tim Sweeney, CEO of Epic Games, described the Epic Games Store launcher as "clunky" and acknowledged that many users find it slow and cumbersome compared to Steam. The Epic launcher received a score of 41% in a recent evaluation, ranking behind competitors like the Microsoft Store and EA, and significantly trailing Steam and GOG Galaxy. Performance issues vary based on a user's proximity to a content delivery network and the size of their game library, with slower internet connections exacerbating loading frustrations. Sweeney believes the Epic launcher should incorporate convenient features from Steam while maintaining its unique advantages. He emphasized the importance of connecting players across platforms and criticized Valve for not allowing cross-platform functionality with Steamworks. Sweeney also addressed negative backlash against developers using Epic Online Services, citing harassment related to crossplay features. Users seeking alternatives to the Epic launcher can consider GOG Galaxy or Heroic, which are noted for better functionality.

The Play ransomware gang exploited a critical vulnerability in the Windows Common Log File System, identified as CVE-2025-29824, to execute zero-day attacks, gaining SYSTEM privileges and deploying malware. Microsoft recognized this flaw and issued a patch during last month's Patch Tuesday. The gang targeted sectors including IT and real estate in the U.S., the financial sector in Venezuela, a Spanish software company, and retail in Saudi Arabia. They used the PipeMagic backdoor malware to deploy the CVE-2025-29824 exploit and install ransomware payloads. Symantec's Threat Hunter Team linked these activities to the Play ransomware-as-a-service operation, noting the use of the Grixba infostealer tool. The Play ransomware group, active since at least June 2022, employs double-extortion tactics and has compromised approximately 300 organizations globally as of October 2023. Notable victims include Rackspace, Arnold Clark, the City of Oakland, Dallas County, Antwerp, and Microchip Technology.

Retired Microsoft engineer Dave Plummer has expressed concerns about the hardware requirements for Windows 11, questioning whether they are genuinely for security or a sales strategy. He noted that many PCs excluded from compatibility due to the lack of TPM 2.0 or modern CPUs are not necessarily old or underpowered. Plummer highlighted that Microsoft's history of discontinuing support for older operating systems, like Windows XP and 7, was typically based on security and compatibility challenges. He warned that future versions of Windows could impose even stricter hardware demands, potentially leaving many functional PCs unable to upgrade. Additionally, he pointed out the ambiguity behind Microsoft's refusal to allow users to opt out of security enhancements if they lack the necessary hardware, raising concerns about potential e-waste. Many users are hesitant to transition to Windows 11, and while hardware compatibility is a factor, it is part of a broader decision-making process. Microsoft’s shift towards a subscription model and the introduction of new hardware requirements suggest a significant evolution in Windows.

BitLocker encryption is enabled by default on most Windows 11 systems, which can hinder the installation of Ubuntu. To proceed with the installation, BitLocker was temporarily disabled through the Control Panel. A bootable USB drive for Ubuntu was created using Rufus with an SK hynix Tube drive. The Ubuntu 25.04 ISO file, known as "Plucky Puffin," was downloaded at 5.8GB in about a minute. The decision was made to install Ubuntu 25.04 instead of the more stable Ubuntu 24.04 LTS due to a desire for the latest features. The installation was planned for both a ThinkPad X1 Carbon and a custom-built desktop with an AMD Ryzen 9 7950X CPU.
