What it detects

This rule flags PowerShell script block content that calls Get-StorageDiagnosticInfo with the -IncludeLiveDump option on Windows. Attackers may use this to collect live memory data, which can aid credential access and other sensitive information discovery. Detection relies on script block text visibility from PowerShell logging to match the specific command and parameter combination.
