Opis

This rule prevents Office apps, including Word, Excel, and PowerPoint, from being used as a vector to persist malicious code on disk. Rule ID and name: - 3b576869-a4ec-4529-8536-b80a7769e899 (Block Office applications from creating executable content) The recommended state for this setting is: 3b576869-a4ec-4529-8536- b80a7769e899:1 (Block). Rationale: Attack surface reduction helps prevent actions and apps that are typically used by exploit-seeking malware to infect machines. Malware that abuses Office as a vector might attempt to save malicious components to disk that would survive a computer reboot and persist on the system. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Windows Defender Exploit Guard\ASR\Rules:3b576869-a4ec-4529-8536-b80a7769e899 (REG_SZ); compliant when it is 1.
