Group Policy Discovery

Adversaries may gather information on Group Policy settings to identify paths for privilege escalation, security measures applied within a domain, and to discover patterns in domain objects that can be manipulated or used to blend in the environment. Group Policy allows for centralized management of user and computer settings in Active Directory (AD). Group policy objects (GPOs) are containers for group policy settings made up of files stored within a predictable network path `\\SYSVOL\\Policies\`.(Citation: TechNet Group Policy Basics)(Citation: ADSecurity GPO Persistence 2016) Adversaries may use commands such as gpresult or various publicly available PowerShell functions, such as Get-DomainGPO and Get-DomainGPOLocalGroup, to gather information on Group Policy settings.(Citation: Microsoft gpresult)(Citation: Github PowerShell Empire) Adversaries may use this information to shape follow-on behaviors, including determining potential attack paths within the target network as well as opportunities to manipulate Group Policy settings (i.e. Domain or Tenant Policy Modification) for their benefit.

LunarWeb

LunarWeb can capture information on group policy settings(Citation: ESET Turla Lunar toolset May 2024)
Turla

Turla surveys a system upon check-in to discover Group Policy details using the gpresult command.(Citation: ESET ComRAT May 2020)

Detection

System and network discovery techniques normally occur throughout an operation as an adversary learns the environment. Data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities based on the information obtained. Monitor for suspicious use of gpresult. Monitor for the use of PowerShell functions such as Get-DomainGPO and Get-DomainGPOLocalGroup and processes spawning with command-line arguments containing GPOLocalGroup. Monitor for abnormal LDAP queries with filters for groupPolicyContainer and high volumes of LDAP traffic to domain controllers. Windows Event ID 4661 can also be used to detect when a directory service has been accessed.
