What it detects

This rule detects a minimized cmd shell chaining ipconfig /release and /renew, a network-flap trick ValleyRAT performs to mask connectivity loss while it installs its stealth kernel driver. The minimized-window start combined with a release-then-renew sequence in one command is anomalous and points to the rootkit installation routine.
