What it detects

This rule detects PowerShell launched with an abbreviated hidden window style argument combined with string reconstruction, a pattern used by ClickFix clipboard lures delivering MIMICRAT. Observed in Elastic Security Labs telemetry where powershell -WInDo Min hides the console while string-slicing rebuilds the attacker domain to fetch the custom RAT.
