Lateral Movement via VPN
This rule detects post-VPN activity indicative of discovery or lateral movement targeting directory services. It specifically looks for commands associated with LDAP, Kerberos, SMB, or WinRM activity to multiple internal systems, often seen after an initial VPN compromise. The rule focuses on processes like PowerShell, cmd, net, nltest, adfind, ldapsearch, wmic, and winrs executing commands related to network enumeration and directory service interaction.
