What it detects

This rule identifies file creation events where the target filename ends with WindowsPowerShell\Modules\webAdministration\webAdministration.psm1, which is expected to appear during local privilege exploitation of CVE-2022-24527. Attackers may leverage this behavior to establish elevated execution context by placing or modifying PowerShell module files. Detection relies on Windows file event telemetry that includes the target filename and associated user context.
