What it detects

This rule detects PowerShell command lines that download remote content with Invoke-WebRequest and immediately pipe it into Invoke-Expression, a pattern used by ClickFix social-engineering lures. This tradecraft was observed delivering GHOSTPULSE and the ARECHCLIENT2 information stealer, where victims are tricked into pasting a clipboard command into the Run dialog to fetch and run a next-stage payload in memory.
