Description

An adversary exploits functionality meant to identify information about user groups and their permissions on the target system to an authorized user. By knowing what users/permissions are registered on the target system, the adversary can inform further and more targeted malicious behavior. An example Windows command which can list local groups is "net localgroup".

Prerequisites

The adversary must have gained access to the target system via physical or logical means in order to carry out this attack.

Mitigations

Identify programs (such as "net") that may be used to enumerate local group permissions and block them by using a software restriction Policy or tools that restrict program execution by using a process allowlist.
