Romanian national oil pipeline operator Conpet reported a ransomware attack that disabled its corporate IT systems and took its website offline for over a week, while the Qilin gang claims to have exfiltrated nearly 1 TB of data, though OT and SCADA remained unaffected.
SCADA systems are essential industrial automation platforms that monitor, collect, and control data across sectors such as energy, manufacturing, and water treatment, using sensors, PLCs, and HMI software, and modern implementations integrate SQL databases and web technologies for enhanced efficiency.
SCADA and DCS originated as separate control systems but have converged over time; SCADA focuses on distributed monitoring and data acquisition across wide geographic areas, while DCS emphasizes centralized control, and modern high‑bandwidth networks now allow them to operate together as a unified monitoring solution.
This article provides an overview of common industrial control system protocols, their security weaknesses, and practical network scanning commands and resources for identifying and assessing SCADA and related devices.
SCADA (Supervisory Control and Data Acquisition) systems are essential industrial automation platforms that monitor and control processes across sectors such as energy, manufacturing, and water treatment, featuring sensor‑to‑PLC/RTU data flow, HMI interfaces, SQL integration, and modern web‑based capabilities exemplified by Ignition software.
This article provides a comprehensive overview of industrial control system terminology, common SCADA‑related protocols such as Modbus, PROFIBUS, DNP3, OPC, BACnet, and Siemens S7, their security weaknesses, detection scripts, and vulnerability analysis resources.
