ClickFix-style PowerShell execution via Run dialog paste after fake verification page
Detects suspicious PowerShell execution patterns characterized by the 'ClickFix' social engineering technique. This involves an attacker tricking a user into copying and pasting a PowerShell command into their terminal, often disguised as a fake reCAPTCHA or security verification page. The rule monitors for PowerShell processes spawned by common user-facing applications (explorer.exe, conhost.exe, WindowsTerminal.exe) that contain specific command-line arguments like 'iex(irm' or 'iex(iwr'.
