Detect Cloud Groups in IBM QRadar
Adversaries may attempt to find cloud groups and permission settings to understand role assignments, privilege levels, and group memberships within a cloud environment. Tools such as Get-MsolRole (Office 365), az ad user get-member-groups (Azure CLI), ROADTools, AADInternals, and Pacu are used to enumerate cloud identity groups. In AWS, ListRolePolicies and ListAttachedRolePolicies enumerate role policies. Adversaries use this information to identify privileged accounts, determine lateral movement paths, and select targets for privilege escalation.

ORDER BY starttime DESC Detects cloud group enumeration (T1069.003) in IBM QRadar by matching two event streams: (1) Microsoft Office 365 and Azure AD DSM events (LOGSOURCETYPEID 352/397) containing group and role read operation names, and (2) Windows Security (Event 4688) and Sysmon (Event 1) process creation events (LOGSOURCETYPEID 12/13) where the command line contains known cloud group enumeration cmdlets or adversarial tools. The devicecustomstring1 field maps to the CommandLine/ProcessCommandLine property in both Windows Security and Sysmon log parsers.
Data Sources
Required Tables
False Positives & Tuning
- Identity governance workflows that run bulk enumeration of Azure AD groups and role assignments using service principals for automated access certification campaigns
- Azure AD Connect or cloud directory synchronization agents that read group membership data as part of scheduled synchronization cycles
- Help desk automation or ITSM integrations using PowerShell runbooks to look up user group memberships during ticket resolution

Testing Methodology
Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Enumerate Azure AD Groups via MSOnline PowerShell Module
Expected signal: Sysmon Event ID 1: PowerShell process creation with CommandLine containing 'Get-MsolRole' and 'Get-MsolRoleMember'. PowerShell ScriptBlock Log Event ID 4104 with full script content. Azure AD Audit Logs: 'List directory roles' and 'List directory role members' operations attributed to the authenticated user. Sysmon Event ID 3: Outbound network connections to login.microsoftonline.com and graph.windows.net.
- Test 2Enumerate Azure AD Groups via Azure CLI
Expected signal: Sysmon Event ID 1: az.cmd process creation with CommandLine containing 'ad group list', 'ad user get-member-groups', 'role assignment list'. Sysmon Event ID 3: Network connections to management.azure.com and graph.microsoft.com. Azure AD Audit Logs: 'List groups', 'List role assignments' operations. File creation events (Sysmon ID 11) for output files in TEMP directory.
- Test 3Enumerate AWS IAM Role Policies via AWS CLI
Expected signal: Sysmon Event ID 1: PowerShell and aws.exe process creation events with CommandLine containing 'list-roles', 'list-role-policies', 'list-attached-role-policies', 'list-groups'. Sysmon Event ID 3: Outbound connections to iam.amazonaws.com (port 443). File creation events for output files. AWS CloudTrail: ListRoles, ListRolePolicies, ListAttachedRolePolicies, ListGroups API calls attributed to the IAM principal.
- Test 4Enumerate Azure AD Groups using Microsoft Graph PowerShell SDK
Expected signal: Sysmon Event ID 1: PowerShell process with CommandLine containing 'Get-MgGroup', 'Get-MgDirectoryRole', 'Get-MgDirectoryRoleMember'. Sysmon Event ID 3: Outbound connections to graph.microsoft.com (port 443). PowerShell ScriptBlock Log Event ID 4104. Azure AD Audit Logs: 'List groups', 'List directory roles', 'List directory role members' operations. Sysmon Event ID 11: CSV file creation in TEMP directory.
