Detects the execution of Ruby with the '-e' flag, which allows for inline script execution, combined with specific keywords related to socket programming ('rsocket', 'TCPSocket') and common shell names ('ash', 'bash', 'bsh', 'csh', 'ksh', 'pdksh', 'sh', 'tcsh'). This combination is a strong indicator of an attempt to establish a Ruby-based reverse shell.
