The 10 Most Impactful Types of Vulnerabilities for Enterprises TodayManaging system vulnerabilities is one of the old est - and most frustrating - security challenges that enterprise defenders face. Every software application and hardware device ships with intrinsic flaws - flaws that, if critical enough, attackers can exploit from anywhere in the world. It's crucial that defenders take stock of what areas of the tech stack have the most emerging, and critical, vulnerabilities they must manage. It's not just zero day vulnerabilities. Consider that CISA's Known Exploited Vulnerabilities (KEV) catalog lists vulnerabilitlies in widely used applications that are "actively exploited," and most of them are flaws that were discovered several years ago and have been fixed. There are also emerging vulnerabilities in 5G networks, cloud infrastructure, Edge applications, and firmwares to consider.

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.
