What it detects
This rule detects PowerShell reading the clipboard and executing it through ScriptBlock Create, the core of the Interlock ClickFix lure. Victims were tricked into pasting a command that pipes a downloaded payload to the clipboard and then runs Get-Clipboard as a script block. This clipboard-to-execution pattern lets attackers gain code execution while hiding the real command from the user.
