Summary of the Pull Request
Adds a new Sigma detection rule for socat-based reverse shell execution on Linux.
Currently, dedicated process_creation reverse shell rules exist for netcat, perl, php, python, ruby, and xterm, but not for socat.
This rule detects execution of socat with exec parameters pointing to a shell combined with outbound TCP or SSL/TLS connections, which is a common pattern for establishing reverse shells.
