If the attacks you defend against leaves a fingerprint in some logfile, you can either shoehorn fail2ban into parsing that logfile and identifying the attacks, or write a custom script that runs every so often, scans the log file and triggers a response when the attack is detected.

The script that runs periodically is not a great alternative (because if you have a scan periodicity of, say, 5 minutes, attackers can do as they want until thy are caught by the next iteration of the scaner). It s simple, though.

I am not familiar with the software you are trying to protect so I cannot be of much help.
