In Group Policy, navigate in this order to: You can do this for all sites by configuring a group policy using your local Group Policy editor or by updating the registry.

If you prefer a more targeted protection and follow just the Microsoft-specific guidance, you can do so by disabling the installation of all ActiveX controls in Internet Explorer.

Using ASR rules protects you not only for the current exploit but for future similar exploits. MicrosoftвЂ™s mitigation focuses on blocking the ActiveX file so it canвЂ™t be called into action. The exploit starts with an ActiveX CAB to place a DLL at a known location on the targeted system. This setting has been available since version 1709 of Windows 10. You can use Group Policy to configure ASR rules.

Microsoft Defender Attack Surface Reduction rulesДЄ vulnerability analyst at the CERT/CC, Will Dorman, pointed out that using Microsoft DefenderвЂ™s Attack Surface Reduction (ASR) rules is a better long-term way to protect against such attacks. Instead, I recommend you keep one key protection that probably many of us are not doing to protect ourselves from malicious Office files including those used in this most current exploit.

Even when itвЂ™s fixed, donвЂ™t let your guard down. Microsoft has released CVE-2021-40444 to track this vulnerability. Your antivirus tools may already include detections for this exploit as well. In addition, Microsoft Defender Antivirus and Microsoft Defender for Endpoint both provide detection and protections for the known vulnerability. So, your first line of defense is an educated user who doesnвЂ™t blindly open unexpected files. The attacker must convince a user to open the malicious document. For this exploit, an attacker crafts a malicious ActiveX control to be used by a Microsoft Office document that hosts the browser rendering engine. rtf files can also be used in such attacks. This time they used the Windows Explorer preview pane to deliver malicious. Once again attackers have used Office files in targeted attacks against Microsoft users.
