Cause→effect chain: (1) A user or service launches an indirection utility (e.g., forfiles.exe, pcalua.exe, wsl.exe, scriptrunner.exe, ssh.exe with -o ProxyCommand/LocalCommand). (2) That utility spawns a secondary program/command (PowerShell, cmd, msiexec, regsvr32, curl, arbitrary EXE) and/or opens outbound network connections. (3) Optional precursor modification of SSH config to persist LocalCommand/ProxyCommand. Correlate process creation, command/script content, file access to %USERPROFILE%\.ssh\config, and network connections from the utility or its child.
