Tested: Windows 11 has fully removed the legacy tool abused by cybercriminals for malware and ransomware, called WMIC

Windows 11 will remove the Windows Management Instrumentation Command-line (WMIC) tool in the upcoming September 2026 Update, marking its complete elimination after being deprecated in earlier versions. Testing of early builds shows that WMIC is no longer accessible, with attempts to use it resulting in a "command not recognized" error. Previously, WMIC was available as an optional feature, but it will no longer be included or reactivatable in the new update. Microsoft stated that this removal aims to improve the security and reliability of Windows, as WMIC has been exploited by cybercriminals for attacks. The September 2026 Update will also introduce other enhancements, including the ability to disable Bing in Windows Search and improvements in app speed.

Researchers find way to weaponize Windows Defender’s own driver

Check Point Research revealed a technique that uses the boot-time remediation driver BTR.sys, part of Windows Defender, to execute kernel-level operations on Windows systems from Windows 7 to Windows 11 25H2. This method does not exploit software vulnerabilities but leverages BTR.sys, which is designed to remove locked malware components. Researchers reverse-engineered its undocumented protocol, leading to the creation of a proof-of-concept tool, BTR_CLI, that can install the driver as a service without standard management protocols. Once operational, BTR.sys can delete or move files, modify registry entries, and remove security binaries, including parts of Defender, during a specific period when the file system is writable. To exploit this technique, an attacker needs administrator privileges, specifically SeLoadDriverPrivilege. Although Microsoft does not consider this a critical issue due to the requirement of pre-existing administrative access, it highlights a significant potential vulnerability. There have been no documented real-world attacks using this technique.

The temporary download folder unleashes 35% of infostealers on Windows

Executing files directly from the temporary download folder is the primary gateway for infostealers targeting Windows systems, accounting for approximately 35% of analyzed infections. The second most common entry point is C:WindowsMicrosoft.NETFramework, appearing in 32% of cases and associated with advanced tactics like process injection. The findings are based on a report by Kaspersky, which analyzed five million records from the dark web. Malicious files often disguise themselves as legitimate software, such as fake codecs or program activators. Kaspersky recommends monitoring exposed assets and not disabling antivirus software during installations.

Microsoft-vendetta hacker has a new zero day that gives system privileges on fully patched Windows

Nightmare Eclipse has released a new zero-day exploit called ShieldBreak, which can bypass Microsoft's RoguePlanet patch (CVE-2026-50656) and allow attackers to gain SYSTEM privileges on fully patched Windows 10, Windows 11, and Windows Server systems. The exploit has been confirmed by security expert Kevin Beaumont, who provided detection methods for it. ShieldBreak is the tenth zero-day from Nightmare Eclipse since April and was released shortly after Microsoft's monthly Patch Tuesday. The exploit allows local privilege escalation and has a 100% success rate on the latest version of Windows 11 and Windows Server 2025, while Windows 10 remains vulnerable. Microsoft is aware of the vulnerability and is investigating it, emphasizing the importance of coordinated vulnerability disclosure. Previous exploits from Nightmare Eclipse include LegacyHive and GreatXML, with earlier vulnerabilities having been patched but recent ones still unaddressed. Microsoft had threatened legal action against Nightmare Eclipse in May but later reconsidered its approach to vulnerability disclosure.

ShieldBreak: New Windows Zero-Day Bypasses Microsoft’s RoguePlanet Patch

Chaotic Eclipse, a security researcher, has revealed a proof-of-concept (PoC) for a new vulnerability called ShieldBreak, which is a zero-day flaw in Microsoft Defender that bypasses the patch for the previously identified CVE-2026-50656 (RoguePlanet). This vulnerability could allow attackers to execute code at the SYSTEM level on affected Windows systems. Chaotic Eclipse tested the PoC on the latest versions of Windows 11 and Windows Server 2025, achieving a 100% success rate. Windows 10 and its server editions are not supported by the PoC but remain vulnerable. Microsoft had issued security updates for RoguePlanet, which has a CVSS score of 7.8, affecting the Malware Protection Engine and representing a local privilege escalation issue. Chaotic Eclipse has previously disclosed two other zero-day vulnerabilities, YellowKey and GreenPlasma, which affect BitLocker and the Windows Collaborative Translation Framework, respectively. Microsoft criticized the public disclosure of these vulnerabilities as irresponsible and emphasized the importance of Coordinated Vulnerability Disclosure.

This VPN firm has created a way to stop Microsoft’s hidden tracking tool on Windows — although it will break some key cloud services

Windscribe has developed an open-source script called deGDID to remove Microsoft's Global Device Identifier (GDID) from Windows systems. The script functions as a firewall against the DeviceAdd endpoint, preventing Microsoft identity services from recognizing the machine as registered. It includes a flag, -Unprotect, to restore default settings if needed. Testing on a Windows 11 machine confirmed its effectiveness, with the -Status flag showing cached identifiers before removal. The tool is compatible with antivirus and endpoint protection but has limitations: it cannot delete keys stored on Microsoft's servers, cannot run on managed systems or domain-joined accounts, and Windows does not provide a built-in method to disable GDID. The identifier persists across IP addresses, regardless of VPN use. Windscribe notes that the script may disrupt certain Microsoft account functionalities, making it a partial solution rather than a comprehensive fix.

Permanently disable Microsoft’s hidden tracker on all Windows 11 versions with this script

Microsoft's Global Device Identifier (GDID) is an internal marker that uniquely identifies each Windows installation across Microsoft services. It is a persistent device-level identifier that remains constant across supported services, and there is no option to disable or regenerate it manually. Windscribe has developed a free utility called deGDID to permanently remove the GDID from Windows systems and prevent its recreation. This tool operates by blocking Microsoft registration pathways and wiping local GDID-related states without altering system files. While it can remove the GDID from the local system, it cannot erase historical records linked to the device. Windscribe provides instructions for using the tool, which is compatible with Windows 10 version 22H2 and all versions of Windows 11 from 21H2 to 25H2. Users should be aware that disabling GDID generation may impact Microsoft services that rely on device identification, but the tool includes an undo feature to revert changes.
