For example, using external data sources to automatically update content in Microsoft Excel spreadsheets.

Loading external contentĭynamic Data Exchange (DDE) is a protocol used for transferring data between applications. To reduce this risk, the latest supported version of Microsoft Office (Microsoft 365 or Office 2021) should be used. It is often the lack of improved security features that allows an adversary to easily compromise older versions of Microsoft Office. Newer versions of Microsoft Office offer significant improvements in security features, functionality and stability. The following Group Policy setting can be implemented to block the use of Flash in Microsoft Office.Ĭomputer Configuration\Policies\Administrative Templates\MS Security Guideīlock Flash activation in Office documents

To reduce this risk, activation of Flash content should be blocked in Microsoft Office documents. Unfortunately, adversaries can use this functionality to embed malicious Flash content in Microsoft Office documents as part of spear phishing campaigns. Microsoft Office applications offer the ability to load embedded Flash content.

For older versions of Microsoft Windows, alternative measures will need to be implemented to mitigate certain threats addressed by ASR, such as the likes of Dynamic Data Exchange (DDE) attacks.įor organisations using Windows Defender Antivirus, the following Group Policy setting can be implemented to enforce the above ASR rules.Ĭomputer Configuration\Policies\Administrative Templates\Windows Components\Windows Defender Antivirus\Windows Defender Exploit Guard\Attack Surface Reduction

Organisations should either implement ASR using Windows Defender Antivirus or use third party antivirus solutions that offer similar functionality to those provided by ASR.

Block Office applications from injecting code into other processes.Block Office applications from creating executable content.Block all Office applications from creating child processes.Block executable content from email client and webmail.In order to use ASR, Windows Defender Antivirus must be configured as the primary real-time antivirus scanning engine on workstations.ĪSR offers a number of Microsoft Office-related attack surface reduction rules, these include: It is designed to combat the threat of malware exploiting legitimate functionality in Microsoft Office applications. Attack Surface ReductionĪttack Surface Reduction (ASR), a security feature of Microsoft Windows 10, forms part of Microsoft Defender Exploit Guard. The following recommendations, listed in alphabetical order, should be treated as high priorities when hardening Microsoft Office deployments. Finally, as Group Policy settings for Microsoft Office are periodically updated by Microsoft, care should be taken to ensure the latest version is always used.

For cloud-based policy configurations, equivalents are available in Microsoft 365 Apps admin centre for many of the Group Policy settings.

The Group Policy Administrative Templates for Microsoft 365, Office 2021, Office 2019 and Office 2016 can be obtained from Microsoft. Before implementing the recommendations in this publication, testing should be undertaken to ensure the potential for unintended negative impacts on business processes is reduced as much as possible. This publication provides recommendations on hardening Microsoft 365, Office 2021, Office 2019 and Office 2016 applications. Hardening applications on workstations is an important part of reducing this risk. Workstations are often targeted by adversaries using malicious websites, emails or removable media in an attempt to extract sensitive information.
