How much damage would there be if power plants were shut down by attackers?

-


"How much damage would there be if power plants were shut down by attackers? Are we even able to do this calculation? What about Oil&Gas, chemical plants, and manufacturing and/or other cases?"


When OT are damaged/infected, the following worst-case scenarios can occur:

  1. Production Downtime and Loss of Operations💰 
  2. Physical Damage to Equipment and Infrastructure💥
  3. Safety Risks and Hazardous Situations💀
  4. Loss of Confidential and Proprietary Data 📃 

etc.. (Quantitative calculation of the fatal explosion: https://trecto.blogspot.com/2025/03/quantitative-calculation-of-large-scale.html)


And, here's a very insightful report from Team82 on the current risky OT situation.

  • 12% of OT devices contain KEVs(7% linked to known ransomwares), and 40% of organizations have insecure connections to the Internet
  • 12% of organizations have OT assets communicating with malicious domains
  • Especially the manufacturing industry has the most devices with confirmed KEVs, 68% of those linked to ransomware groups


So, what should we prepare for now? It may be necessary to go on a journey to meet the security requirements of reference guidelines/standards at the global/national level. I will post about these requirements separately.

Don't confuse DCS, PLC and SCADA in front of OT specialists

DCS, PLC and SCADA are not the same. If you keep talking only about PLC security in front of the Oil&Gas industry executives where DCS is the main focus, they will not recognize you as a proper expert. We need to understand the characteristics of OT systems such as DCS, PLC, and SCADA accurately, also respect each OT culture uniquely and finally approach the sites in the right way. Don't be confused, here’s a clear and accurate explanation of DCS, PLC, and SCADA . 1. Distributed Control System (DCS) Concept A DCS (Distributed Control System) is an automated control system used for large-scale industrial processes that require continuous operation and high reliability. It consists of multiple controllers distributed throughout the system, which communicate with each other to manage complex processes. Key Features Used in large-scale, continuous processes (e.g., oil refineries, power plants). Decentralized control architecture with multiple controllers working together. Pr...

A comprehensive list of 20 threat scenarios in OT security along with detailed descriptions and detection rules that can help identify and respond to these threats. This playbook-style table covers different types of attacks—from unauthorized access to insider abuse—with corresponding rules and indicators to alert security teams. # Threat Scenario Detailed Description Detection Rules & Indicators 1 Unauthorized Remote Access Attempt An attacker uses stolen or weak credentials to access OT networks remotely. - Log Analysis: Monitor VPN/RDP logs for unusual login times, geolocation mismatches, and failed/successful login bursts. - User Behavior Analytics (UBA): Alert on deviations from normal remote access patterns. - Anomaly Detection: Trigger an alert when a remote session is initiated from an unusual IP or geographic region. 2 Malware/Ransomware Infiltration in OT Network Malicious code is introduced into the OT network via compromised endpoints or phishing, potentially encr...

Let's create our own ICS Labs in the VMs: A Step-by-Step Guide Building an Industrial Control System (ICS) lab in a virtualized environment allows security researchers, engineers, and penetration testers to safely simulate industrial networks, study threats, and test security defenses. Below is a detailed step-by-step guide to creating an ICS lab , including HMI, EWS, PLC, and other critical components. 1. Lab Architecture Overview Key Components in an ICS Lab: HMI: Graphical interface for controlling industrial processes. Engineering Workstation (EWS): Used to configure PLCs and SCADA systems. PLC: Controls physical processes (e.g., motors, valves). SCADA System: Supervisory control and monitoring of ICS networks. Historian: Logs and stores process data for analysis. Networking Components: Virtualized switches, routers, and firewalls to segment ICS networks. Attacker Machine: Kali Linux or Metasploit for penetration testing. 2. Choosing the Virtualization ...
