T1069: Permission Groups Discovery

Adversaries may attempt to discover group and permission settings. This information can help adversaries determine which user accounts and groups are available, the membership of users in particular groups, and which users and groups have elevated permissions.

Adversaries may attempt to discover group permission settings in many different ways. This data may provide the adversary with information about the compromised environment that can be used in follow-on activity and targeting.

Detection

IDDS0009Data source and componentProcess: Process CreationDescription

Monitor for newly constructed processes and/or command-lines for actions that could be taken to gather system and network information. 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, such as Lateral Movement, based on the information obtained.

IDDS0036Data source and componentGroup: Group MetadataDescription

Monitor for contextual data about a group which describes group and activity around it.

IDDS0017Data source and componentCommand: Command ExecutionDescription

Monitor executed commands and arguments acquired through Windows system management tools such as Windows Management Instrumentation and PowerShell.

IDDS0015Data source and componentApplication Log: Application Log ContentDescription

Monitor for logging, messaging, and other artifacts provided by cloud services.

IDDS0036Data source and componentGroup: Group EnumerationDescription

Monitor for an extracted list of ACLs of available groups and/or their associated settings.
