It protects you when unconstrained delegation is being used for nefarious tasks such as stealing your ticket-granting service in Kerberos. Credential Guard uses virtualization-based security to isolate secretive and important data for its protection. In the Insider preview build 22526, Credential Guard will be enabled by default for Windows Enterprise and an E5 licensees. Microsoft is starting to test the waters in enabling tools such as Credential Guard for qualifying Windows systems. While this won’t stop attacks by any means, it’s another step in making it a bit harder for attackers to use techniques and tools that are built into the operating system. While WMI itself is not impacted, Microsoft is recommending Windows PowerShell for WMI going forward. It is deprecating or slowly moving away from the Windows Management Instrumentation Command (WMIC) tool.
#MICROSOFT SECURITY DEFAULTS CODE#
Microsoft is moving to disable and define what code is uniquely allowed to run on a system. If an attacker doesn’t bring any new code into your system when they launch their attack, it’s much harder to identify and detect an attack. Living off the land (LOL) or living off the land binaries and scripts (LOLBAS) is using files and tools that are built into the operating system. Microsoft is also starting to disable some of the “living off the land” (LOL) attack techniques. You can even completely disable Visual Basic for Applications in your network with the Group Policy setting “Disable VBA for Office applications.” Making it harder for attackers to live off the land

Change how antivirus software scans encrypted VBA macros.

First, download an appropriate Group Policy administrative template. With Group Policy settings, administrators have been able to block macros by default as far back as Office 2016. You should also evaluate if you want to take actions to block other macro settings using Intune with Azure Active Directory or Group Policy with Active Directory. At a date to be determined, Microsoft plans to make this change to Office LTSC, Office 2021, Office 2019, Office 2016 and Office 2013.
#MICROSOFT SECURITY DEFAULTS UPDATE#
Later, the change will be available in the other update channels, such as Current Channel, Monthly Enterprise Channel, and Semi-Annual Enterprise Channel. The change will begin rolling out in Version 2203, starting with Current Channel (Preview) in early April 2022. This change affects only Office on devices running Windows and Access, Excel, PowerPoint, Visio and Word. If you’ve downloaded macro-based templates from websites, mark these files as trusted and remove the “mark of the web” from the files to ensure that they continue to work. Setting this as the default will mean that you’ll be better protected. Specially, Visual Basic Application obtained from the internet will be blocked by default.
Launching malicious macros is a common way that attackers can gain access to computer systems and launch lateral attacks. The first major change in an Office 365 default blocks internet macros by default. This includes blocking macros by default, limiting native tools used by attackers, and activating Credential Guard by default. Microsoft changes default settings for a variety of reasons, but some recent key changes will keep us safer from attacks, specifically ransomware.
