Detects instances where OpenVPN service binaries (openvpn.exe or openvpnserv.exe) spawn command-line interpreters (cmd.exe or powershell.exe) with suspicious command-line characters or potentially unbalanced quotes. This behavior may indicate an attempt to leverage OpenVPN for code execution or persistence, often seen in environments where VPN configurations are manipulated to run arbitrary scripts.
