What it detects

This rule detects execution of the Invoke-HuntSMBShares PowerShell cmdlet used to enumerate accessible network shares and their permissions. APT42 ran this PowerHuntShares tooling to map file shares for data collection during their operations. Broad SMB share hunting from PowerShell is a strong network discovery indicator in interactive intrusions.
