Hunting ClickFix Win + X Variants

The post analyzes newer ClickFix initial-access lures that replace the well-known Win+R execution path with Windows Power User Menu (Win+X) workflows and user-launched Terminal sessions to avoid RunMRU registry artifacts. It maps the process trees for several execution paths on Windows 11, showing that Win+X typically produces explorer.exe -> wt.exe -> WindowsTerminal.exe -> powershell.exe, while direct Terminal launches often omit wt.exe unless a specific profile is chosen, in which case wt.exe includes a -p profile GUID parameter. The article also distinguishes direct shell launches, where Explorer.exe can spawn powershell.exe directly and svchost.exe may separately launch WindowsTerminal.exe, giving defenders a way to separate malicious paste-and-run behavior from normal user activity. The practical value is in building higher-fidelity analytics around parent/child relationships, command-line parameters, and Terminal launch patterns to detect ClickFix variants that intentionally sidestep older detections focused on the Run dialog.
