Marcel Rick-Cen’s new course, Practical Offensive Industrial Security Essentials, is designed to revolutionize industrial cybersecurity by focusing on offensive techniques to strengthen defenses. This hands-on training covers:
- Attack vectors in OT devices and networks
- Exploitation of common weaknesses
- Attack surface mapping
- Adversarial thinking for better defense strategies

You Should Know: Essential ICS/OT Security Commands & Techniques
1. Network Reconnaissance in OT Environments
Scan for open ports on an OT device nmap -sS -Pn -T4 -p- 192.168.1.100 Identify ICS protocols (Modbus, DNP3, S7) nmap --script modbus-discover,dnp3-info,s7-info -p 502,20000 192.168.1.100
2. Exploiting Weak Protocols
Using Metasploit for Modbus exploitation msfconsole use auxiliary/scanner/scada/modbusdetect set RHOSTS 192.168.1.100 run Simulating a PLC attack with PLCinject python3 plcinject.py -i 192.168.1.100 -p 502 -c "stop_process"
3. Defensive Hardening for OT Networks
Block unauthorized Modbus traffic with iptables sudo iptables -A INPUT -p tcp --dport 502 -j DROP Monitor ICS traffic with Wireshark filters wireshark -k -Y "modbus || dnp3 || s7comm"
4. Windows-based OT Security Checks
Check for insecure SCADA services
Get-Service | Where-Object { $<em>.DisplayName -like "SCADA" -and $</em>.Status -eq "Running" }
Disable legacy protocols (SMBv1)
Disable-WindowsOptionalFeature -Online -FeatureName smb1protocol
5. Logging & Anomaly Detection
Monitor syslog for OT device anomalies tail -f /var/log/syslog | grep "PLC|HMI|SCADA" Use Zeek (Bro) for ICS traffic analysis zeek -i eth0 -C -s modbus.bro
What Undercode Say
Industrial Control Systems (ICS) and Operational Technology (OT) security requires a proactive approach—understanding offensive techniques is critical for defense. This course bridges the gap between IT and OT security, emphasizing real-world attack simulations. Future attacks on critical infrastructure will leverage weak protocols, default credentials, and unpatched systems. Strengthening OT security involves:
- Network segmentation (
iptables, VLANs) - Protocol hardening (disabling Telnet, using encrypted Modbus/TCP)
- Continuous monitoring (Zeek, Wireshark, SIEM integrations)
- Red team exercises (Metasploit, PLCinject, custom exploit scripts)
The rise of ransomware targeting OT (e.g., Industroyer2) means defenders must adopt adversarial thinking—this course is a step toward that future.
Prediction
By 2026, ICS/OT attacks will increase by 200%, with ransomware groups specifically targeting water treatment plants, power grids, and manufacturing systems. Organizations that invest in offensive security training will be better prepared to mitigate these threats.
Expected Output:
A structured, actionable guide on ICS/OT offensive security with verified commands, defensive tactics, and future threat predictions.
