This rule blocks Office apps from injecting code into other processes. Office apps included in this setting are Word, Excel, PowerPoint, and OneNote. Rule ID and name: - 75668c1f-73b5-4cf0-bb93-3ecf5cb7cc84 (Block Office applications from injecting code into other processes) The recommended state for this setting is: 75668c1f-73b5-4cf0-bb93- 3ecf5cb7cc84:1 (Block). Rationale: Attack surface reduction helps prevent actions and apps that are typically used by exploit-seeking malware to infect machines. Attackers might attempt to use Office apps to migrate malicious code into other processes through code injection, so the code can masquerade as a clean process. 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:75668c1f-73b5-4cf0-bb93-3ecf5cb7cc84 (REG_SZ); compliant when it is 1.
