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.[1]

Procedure Examples

IDNameDescription
G0022 APT3

APT3 has a tool that can enumerate the permissions associated with Windows groups.[2]

G0096 APT41

APT41 usednet group commands to enumerate various Windows user groups and permissions.[3]

S0335 Carbon

Carbon uses thenet group command.[4]

G1016 FIN13

FIN13 has enumerated all users and roles from a victim's main treasury system.[5]

S0483 IcedID

IcedID has the ability to identify Workgroup membership.[6]

S0233 MURKYTOP

MURKYTOP has the capability to retrieve information about groups.[7]

G1015 Scattered Spider

Scattered Spider has enumerated the vSphere Admins and ESX Admins groups in targeted environments.[8]

S0445 ShimRatReporter

ShimRatReporter gathered the local privileges for the infected host.[9]

S0623 Siloscape

Siloscape checks for Kubernetes node permissions.[10]

C0024 SolarWinds Compromise

During theSolarWinds Compromise,APT29 used theGet-ManagementRoleAssignment PowerShell cmdlet to enumerate Exchange management role assignments through an Exchange Management Shell.[11]

G0092 TA505

TA505 has used TinyMet to enumerate members of privileged groups.[12]TA505 has also runnet group /domain.[13]

S0266 TrickBot

TrickBot can identify the groups the user on a compromised host belongs to.[14]

G1017 Volt Typhoon

Volt Typhoon has used commercial tools, LOTL utilities, and appliances already present on the system for group and user discovery.[15]

Mitigations

This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.

Detection Strategy

IDNameAnalytic IDAnalytic Description
DET0179Behavioral Detection of Permission Groups DiscoveryAN0507

Detection of adversary enumeration of domain or local group memberships via native tools such as net.exe, PowerShell, or WMI. This activity may precede lateral movement or privilege escalation.

AN0508

Detection of group enumeration using commands like 'id', 'groups', or 'getent group', often followed by privilege escalation or SSH lateral movement.

AN0509

Group membership checks via 'dscl', 'dscacheutil', or 'id', typically executed via terminal or automation scripts.
