You Should Know: Essential OT/ICS Cybersecurity Commands & Tools
1. Network Scanning & Discovery (OT Environments)
Nmap for ICS device discovery (non-intrusive) nmap -sS -Pn -T4 --script=banner -p 502,102,443,80 <OT_IP_Range> Shodan CLI for ICS device search shodan search --fields ip_str,port,org,hostnames product:modbus
2. Modbus Protocol Interaction
Using mbpoll for Modbus queries mbpoll -a 1 -b 9600 -P none -t 3 -r 1 -c 5 /dev/ttyUSB0 Metasploit Modbus scanner use auxiliary/scanner/scada/modbusdetect set RHOSTS <Target_IP> run
3. ICS Firewall & Traffic Analysis
Zeek (Bro) for ICS traffic logging zeek -i eth0 -C ICS.conf Suricata IDS rules for SCADA protocols suricata -c /etc/suricata/suricata.yaml -i eth0
4. PLC Exploitation & Security Testing
PLCScan for Siemens S7 devices python plcscan.py -d <Target_IP> ISF (Industrial Exploitation Framework) use exploit/windows/scada/ge_proficy_cimplicity set RHOST <Target_IP> exploit
5. OT Vulnerability Assessment
OpenVAS for ICS vulnerability scanning openvas-setup openvas-start Using Nmap NSE scripts for SCADA vulns nmap --script=scada,modbus <Target_IP>
6. ICS Incident Response & Forensics
GRR Rapid Response for OT environments grr_console --config=grr-server.yaml Log analysis for ICS attacks grep -i "unauthorized access" /var/log/syslog
