These statistics underscore the critical need for robust cybersecurity measures to protect against ransomware and other threats.¹

Supply Chain Vulnerabilities

The interconnected nature of supply chains creates additional vulnerabilities, as evidenced by the ransomware infection of PSI Software in February 2023. This incident highlights the broader risk of supply-chain attacks, where exploiting a vulnerability in commonly used software or equipment can have widespread consequences.²

Operational Technology (OT) and Industrial Control Systems (ICS) Security Risks

As part of Industry 4.0, the future of manufacturing with OT and ICS involves greater integration with advanced technologies such as the IoT, artificial intelligence (AI), and machine learning (ML). These integrations aim to further enhance automation, improve predictive maintenance, increase operational efficiency, and drive innovation in manufacturing processes.

While OT and ICS bring numerous benefits to manufacturing, they also present challenges, particularly in cybersecurity, where integrating IT (Information Technology) and OT systems increases the risk of cyberattacks. Incidents such as the Oldsmar water treatment plant attack in February 2021 demonstrate the potential for significant disruptions caused by such vulnerabilities.³ Addressing these challenges involves continuous advancements in cybersecurity practices, regular system updates, and adherence to industry standards and best practices.

Increased Targeting by Ransomware and Advanced Persistent Threats (APTs): The manufacturing sector, including OT and ICS environments, continues to be a prime target for ransomware attacks, with a significant portion of such incidents originating from IT networks. This underscores the need for better network segmentation between IT and OT environments to prevent the spread of malware​.​​^4,5

Exploitation of IoT/IIoT Vulnerabilities: The expansion of IoT and IIoT devices broadens the attack surface, making these devices prime targets for cybercriminals. The use of vulnerable open-source software libraries in these devices further complicates vulnerability remediation. This situation calls for improved security governance, including regular updates and patches to IoT/IIoT devices and stricter controls on device procurement and disposal practices​.⁶

Session Hijacking in Remote Access: There’s an increase in session hijacking attacks, where attackers capture users’ credentials or hijack remote sessions to access sensitive data and systems. This type of attack is potent, difficult to detect, and can have physical impacts on operational availability and safety if it connects to OT and ICS​.⁷

Nation-state Actors Targeting Critical National Infrastructure: Global geopolitical tensions have heightened the threat from nation-state actors targeting critical infrastructure through OT systems. These high-level adversaries have the resources to test security measures extensively, looking for gaps to exploit. The convergence of IT and OT networks, although beneficial in many respects, creates additional vulnerabilities that threat actors can exploit​​.⁸

Unchecked Outbound Communication: If not properly monitored and controlled, outbound communication from ICS/OT environments can serve as a channel for data exfiltration and unauthorized remote control of network assets. It’s essential to implement strict rules and configurations on firewalls and gateway devices to limit communication to necessary and trusted external endpoints​​.⁹

Need for Continuous Assessment and Adaptation: The evolving nature of cyber threats demands a proactive approach to security. This includes regular security assessments to identify vulnerabilities and adapting security practices based on the latest threat intelligence. Continuous learning and adaptation are crucial for staying ahead of attackers.¹⁰
