Cybersecurity researchers have identified two new Windows variants of the SprySOCKS backdoor, named WINDRV and WINPLUS, which were previously thought to be exclusive to Linux systems. Both variants feature hard-coded command-and-control configurations and can communicate via TCP, UDP, and WebSocket protocols. They support over 30 commands for operations such as system information collection and file management. WINDRV employs kernel drivers for stealth, obscuring network connections and allowing TCP traffic diversion. SprySOCKS was first documented by Trend Micro in September 2023, linked to the Chinese state-sponsored threat actor Earth Lusca, also known as FishMonger. The Windows variants belong to version 1.8 of SprySOCKS and utilize a kernel driver named RawWNPF for enhanced stealth. The attack chain begins with an initial access method that drops a batch script, leading to the installation of the backdoor. Evidence suggests these variants may have been used in attacks against government organizations in Honduras, Taiwan, Thailand, and Pakistan between 2023 and 2024. The WINPLUS variant was first detected in July 2024 in Pakistan. There are indications of a potential UEFI bootkit involvement exploiting CVE-2023-24932, a vulnerability in the Windows Boot Manager.

Windows 11 update KB5094126 (Build 26200.8655), released on June 9, 2026, has caused boot failures, blue screens, and BitLocker recovery prompts for users, particularly affecting business devices from HP and Dell, including models like HP EliteBook 840 G10 and Dell Precision 7530. The issues stem from changes in Secure Boot and EFI partition modifications, with insufficient EFI partition space leading to errors. A workaround involves disabling Secure Boot in BIOS. Additionally, users have reported disruptions with OneDrive and Microsoft Word integration, particularly in enterprise environments. Microsoft has not yet acknowledged these problems.

Microsoft released update KB5094126 on June 9, 2026, for Windows 11 versions 24H2 and 25H2 to improve shell responsiveness. This update introduces the Low Latency Profile, which temporarily boosts CPU frequency for one to three seconds during interactions with system features like the Start menu and taskbar, resulting in system flyouts opening up to 70% faster and core applications launching up to 40% quicker. The update also includes features such as Shared Audio for simultaneous audio use by two users, enhanced Windows Task Manager with NPU usage columns, the ability for multiple applications to access the same camera stream, improved Windows Search for locating files with two characters, a refined installation process allowing custom user folder names, and optimizations to Windows Hello for authentication methods. The update also addresses over 200 security vulnerabilities.

Microsoft released a cumulative update for Windows 10, designated as KB5094127, during the latest Patch Tuesday. Some users are experiencing issues where they are prompted to enter their BitLocker recovery key after installing the update. This problem is linked to systems with an "unrecommended" BitLocker Group Policy configuration and has occurred in previous updates. Specific conditions that can lead to this issue include having BitLocker enabled on the operating system drive, a certain Group Policy setting configured, the System Information tool reporting a specific Secure Boot State, the presence of a particular certificate in the Secure Boot Signature Database, and not using the 2023-signed Windows Boot Manager. Affected users may face difficulties accessing their BitLocker recovery key, potentially leading to lockouts. Microsoft suggests that personal devices are less likely to be affected, with the issue primarily impacting enterprise setups. The company is working on a resolution and advises IT administrators to consider removing the Group Policy configuration before installing the update. Update KB5094127 is available only to Windows 10 users in the Extended Security Updates program for versions 21H2 and 22H2, addressing various bugs and security vulnerabilities.

Google will soon notify Android users when an app they installed has lost developer support. Currently, users only receive alerts from Play Protect for significant security threats or potentially harmful apps. The only way to discover if an app has been delisted is through external sources or by trying to install it on a new device. Recent findings in the Play Store indicate that Google is preparing to inform users when apps have been removed from the Play Store and will no longer receive updates. Abandoned apps pose significant security risks, as they may contain vulnerabilities that can be exploited by malicious actors. Google's new notifications aim to encourage users to uninstall unsupported apps to protect their personal data.
