What it detects

This rule detects PowerShell importing the ActiveDirectory module and running Get-ADComputer with an export of results to a CSV file, the domain-inventory reconnaissance performed in this multi-gang intrusion to catalog hosts before lateral movement. Adversaries dump computer objects with descriptions and operating-system fields to plan their spread, so Get-ADComputer piped into Export-CSV outside routine administration is a reconnaissance indicator.
