Local Group Membership Enumerated via SMB
This rule detects attempts to enumerate local group memberships on a target system via the Server Message Block (SMB) protocol. Specifically, it looks for the 'NetLocalGroupEnum' function call within SMB traffic directed to the home network on port 445. This activity is often associated with reconnaissance phases of an attack, where an adversary is trying to discover local user groups to identify potential targets for privilege escalation or lateral movement.
