Antivirus Entry - Go to antivirus and program the software to look for "imain.bin, inject.bin and trilog.exe". Also, I recommend using Comodo HIDS or other software solutions that initiate system baselines. If the system identifies any changes, then the application would stop the file from executing if it was considered nefarious.
From a linux standpoint:
iptables -I INPUT 1 -p tcp -m multiport --dport 39929 -m conntrack --ctstate NEW,ESTABLISHED -j DROP (iptables FW that tracks and Drops the port)
or
ufw allow in proto tcp from 0.0.0.0/0 to 0.0.0.0 port 39929 comment "Triton Blocked Port" (UFW Firewall Entry)
Download chkrootkit and/or rkhunter on the Linux/Unix machines to help find this potential problem.
