Windows BitLocker zero-day gives access to protected drives, PoC released

A cybersecurity researcher known as Chaotic Eclipse has released proof-of-concept exploits for two unpatched vulnerabilities in Microsoft Windows: YellowKey, a BitLocker bypass, and GreenPlasma, a privilege-escalation flaw. The YellowKey vulnerability affects Windows 11 and Windows Server 2022/2025, allowing unauthorized access to BitLocker-protected volumes by exploiting the Windows Recovery Environment. The exploit can be executed using specially crafted 'FsTx' files on a USB drive or directly on the EFI partition. Independent researcher Kevin Beaumont has validated the exploit, which can bypass BitLocker protections even in a Trusted Platform Module (TPM) environment. The GreenPlasma vulnerability allows unprivileged users to create arbitrary memory-section objects, potentially leading to privilege escalation. Chaotic Eclipse has expressed dissatisfaction with Microsoft's handling of bug reports, prompting the public disclosure of these vulnerabilities. Microsoft has stated its commitment to investigating security issues and updating affected devices.

There’s a right way to wipe your Windows PC before getting rid of it – here’s how I do it

Many individuals and businesses consider acquiring a new PC at the start of the year and must decide what to do with the old device. Options include passing it down, reallocating it, donating, selling, or trading it in. Before doing so, it's essential to migrate apps and files, securely erase personal data, and reset the operating system. To migrate apps and files, users can utilize the Windows Backup app on their old PC to back up settings and installed apps, as well as personal folders to OneDrive. Upon setting up the new PC with the same Microsoft account, users can restore their profile. It's also important to compile a list of legacy software and ensure necessary activation codes are available. For data backup, users can use cloud storage services or create an image backup on a removable hard drive. To securely wipe old data, Windows 11 Pro users can enable BitLocker Disk Encryption, while Windows 11 Home users should delete sensitive files and use the command cipher /w:c: to wipe the disk space. For preparing the old PC for a new owner, users can choose one of three options to install a new copy of Windows 11: 1. Reset - Navigate to Settings > System > Recovery and select "Reset PC," choosing "Remove everything" and either Cloud Download or Local Reinstall. 2. Reimage - If specific drivers are needed, check for a recovery image in Settings > System > Recovery or download one from the manufacturer’s website. 3. Reformat and clean install - Create bootable installation media using the Media Creation Tool, ensure Windows is activated, reformat the system disk, and install Windows 11, which will activate automatically for the new owner.

How to turn a Windows 10 laptop into a Chromebook

Many laptops are facing obsolescence as Windows 10 support ends, but users can install Google’s ChromeOS Flex on older devices for improved performance and security. To install ChromeOS Flex, users need a Windows 10 laptop, a USB drive or SD card with at least 8GB of storage, a stable internet connection, and a Google account. The installation process involves creating a boot drive using the Chromebook Recovery Utility, testing ChromeOS Flex, and then proceeding with the full installation if satisfied. The installation will erase the existing Windows installation, so backing up important data is recommended. ChromeOS Flex can run on various laptops, including unsupported hardware, though this may lead to minor glitches.

How to use DISM command tool to repair Windows 10 image

The Deployment Image Servicing and Management (DISM) tool is a command-line utility in Windows 10 used for preparing, modifying, and repairing system images, including the Windows Recovery Environment, Windows Setup, and Windows PE. It can address various system issues, and when system files are missing or corrupted, the System File Checker (SFC) can replace them using the recovery image. If local image files are compromised, the SFC command may fail, and using the "install.wim" image file with DISM can repair the image, allowing SFC to function without a complete OS reinstallation. DISM includes commands such as "CheckHealth," "ScanHealth," and "RestoreHealth" for repairing system images. The "CheckHealth" command identifies corruptions without repairing them, while "ScanHealth" performs a comprehensive scan for underlying issues. The "RestoreHealth" command scans and repairs common problems, connecting to Windows Update to download and replace damaged files if needed. If DISM encounters difficulties, an "install.wim" or "install.esd" file can be used as an alternative source for repairs. The Media Creation Tool can download a fresh Windows 10 ISO file if necessary. Specific commands can be executed to repair the image using these files, and troubleshooting common errors may involve checking for source file locations or ensuring a stable internet connection. Once the image is restored, the SFC command can be run to repair the installation of Windows 10. The SFC tool checks and repairs system files using local image files, with logs saved for further review. DISM does not delete files, and its execution time can vary based on system speed and the extent of corruption.

I’m not upgrading to Windows 11, but I’m not tolerating Linux either

The author has been using an HP Pavilion laptop for a decade, but its performance on Windows 11 has declined due to modern applications and web standards. The laptop's 4th-gen i5 processor struggles with current operating system demands, leading to slowdowns during simple tasks. Attempts to optimize Windows 11 provided only marginal improvements. The author considered switching to Chrome OS Flex for its lightweight nature but found its reliance on web applications and lack of support for certain software limiting. Linux was also considered but deemed too complicated and incompatible with essential Windows-native applications. Ultimately, the author decided to install Chrome OS using the Brunch Framework, which allowed the aging laptop to run more efficiently and support the Google Play Store, improving overall performance and user experience.
