What it detects

This rule flags PowerShell module activity invoking Get-ADDBAccount with parameters indicating it will use BootKey and DatabasePath to read from an ntds.dit database. Attackers may use this to extract credential material without deploying common credential-dumping tools. It relies on PowerShell module telemetry capturing the script payload content, specifically the presence of Get-ADDBAccount along with BootKey and DatabasePath strings.
