Industrial infrastructures have become prime targets for cyber attacks. Often orchestrated by malicious actors, including state-sponsored groups. The impact of these attacks can be devastating, both operationally and financially.
Anticipating cyber attacks on industrial infrastructures means putting in place solid defences. This article guides you through the risks, solutions and best practices for securing your systems.
Definition: An industrial cyber attack is a malicious attempt to compromise industrial control systems (ICS). It aims to gain illegal access to networks or devices in order to steal, modify or destroy sensitive data.
The growing interconnection of OT and IT networks is increasing the exposure of critical industrial infrastructures to cyber threats. Ces systèmes, essentiels à la production d’énergie, au transport et à la fabrication, deviennent des cibles majeures.
Nearly 60% of cyber attacks on critical infrastructure are carried out by state-affiliated groups. These groups often seek to destabilise vital sectors in order to achieve geopolitical objectives. The average cost of a data breach reached 4.45 million dollars in 2023.
Examples of industrial cyberattacks
Cyber attacks on industrial infrastructures can take a variety of forms. Among the most common are the following examples of industrial cyber attacks:
In this section, we will look at three major risks associated with cyber attacks on industrial infrastructures.
Cyber attacks cause considerable direct and indirect financial losses to critical industrial infrastructures. Production interruptions caused by ransomware result in losses of up to several million euros. These incidents include remediation costs: checking backups, replacing systems, audits and security updates.
The indirect costs include fines for non-compliance, high insurance premiums, as well as legal fees. These expenses are in addition to the costs related to loss of revenue during business interruptions.
For small and medium-sized businesses, these costs can be unbearable, jeopardizing their financial viability. These businesses often have limited resources to absorb such losses and strengthen their defenses. It is crucial to invest in robust cybersecurity solutions and proactive strategies. This helps reduce the financial risks associated with industrial cyberattacks.
A cyberattack on critical industrial infrastructures can completely cripple a company’s operations. The attack disrupts production, inventory management, and order tracking. This leads to a loss of visibility over key processes, directly impacting the supply chain. Delivery times are extended, affecting customer satisfaction and the company’s image.
Online sales and other business opportunities are also compromised, amplifying the losses. Interruptions can last for weeks or even months, significantly increasing the loss of revenue. The loss of employee productivity and the overall slowdown of activities exacerbate these disruptions.
The impact becomes more significant as recovery costs increase. The consequences of such paralysis are not limited to direct losses. They also affect relationships with partners, customers, and shareholders. The ability to quickly restore operations becomes essential to minimize long-term damage.
Cyberattacks have a profound impact on the reputation of industrial companies. In cases of compromise of sensitive data, customer trust is quickly eroded. The loyalty of existing customers is undermined, and acquiring new contracts becomes more challenging. A cyberattack reveals a lack of cybersecurity diligence, thereby alarming investors and partners.
This lack of trust can lead to a growing loss of interest in the company, resulting in a devaluation of the brand. The company risks losing business opportunities and its competitive position in the market. Employees also feel the effects of the crisis, particularly on their morale. The stress caused by managing the attack disrupts the smooth running of operations.
This can lead to further delays, worsening the company’s operational and financial situation. Reputation is a crucial intangible asset, and restoring it after a cyberattack can take years.

The cybersecurity of industrial infrastructures relies on proactive risk management, according to the NIST Cybersecurity Framework, which is based on five essential functions: Identify, Protect, Detect, Respond, and Recover. These functions form a comprehensive approach to prepare, defend, and recover from cyberattacks.
To protect yourself, it is essential to have an accurate knowledge of your digital assets. Do you really know your system? Do you know how many devices are connected and where they are located? Most industrial companies cannot answer these fundamental questions with precision. A detailed mapping and inventory allow for a clear definition of the scope and better security of the infrastructures.
A cybersecurity audit helps identify vulnerabilities and specific risks in your system. This comprehensive analysis identifies potential weaknesses and evaluates the sensitive areas of your industrial infrastructures. It includes the examination of networks, processes, technologies, and existing security policies. Conducting an audit provides a clear view of your current posture and the necessary improvements. This approach results in a precise roadmap to effectively strengthen your cybersecurity.
Request an industrial cybersecurity audit to build an action plan tailored to your needs.
Employee training is essential to protect your infrastructures against cyberattacks. Human errors are often the cause of cyberattacks, such as clicking on malicious links. Regular sessions on best practices and threat recognition significantly reduce this risk. The training should include handling sensitive data and recognizing phishing attacks.
Rapid incident detection and quick data recovery are essential in a cybersecurity framework. Regular and secure backups of critical data allow systems to be restored after a cyberattack. These backups must be frequently verified to ensure they remain intact and accessible when needed. This is part of the recover function, which ensures the resilience of infrastructures during a crisis. A strong recovery strategy limits the impact of attacks and enables rapid restoration of operations. This reduces downtime and ensures business continuity despite potential threats.
Good backup practice - 3-2-1 strategy: keep three copies of your data, on two different media (e.g., hard drives and cloud), and one copy off-site. This approach enhances the resilience of your backups.
A well-defined Business Continuity Plan (BCP) and Disaster Recovery Plan (DRP) are crucial. They outline the necessary actions to maintain critical operations during a cyberattack. These plans help prioritize and coordinate efforts during the crisis. They ensure a quick recovery after the incident and minimize the impact on operations. It is essential to regularly update these plans to ensure their effectiveness. Test your BCP and DRP regularly to verify their validity and effectiveness in real-life situations.
Attack simulations are an effective way to detect weaknesses in your security. Penetration tests and exercises help evaluate your infrastructure's responsiveness to cyber threats. These tests not only check defense mechanisms but also assess your team's preparedness for attacks. This minimizes the impact of intrusions and improves crisis management. These exercises help identify vulnerabilities that automated solutions may not detect. They thus help you strengthen your defenses accordingly, ensuring better resilience.
To protect your infrastructures against cyber threats, it is crucial to use appropriate security tools. NIST recommends using firewalls, antivirus software, and intrusion detection systems (IDS/IPS). These tools play a key role in defending industrial networks and systems. However, they must be regularly updated to address evolving threats. The integration of real-time monitoring helps quickly detect suspicious activities. This aids in responding proactively and minimizing the impact of cyberattacks.

In the event of an industrial cyberattack, speed and accuracy of actions are crucial to limit the damage. An appropriate response requires prior preparation, a good understanding of security processes, and efficient resource management to contain and resolve the situation. This section explores the best practices of industrial cybersecurity to follow in case of an attack. The goal is to ensure a quick and effective response, while preserving the integrity and availability of the industrial infrastructure.
Immediately disconnect the network (Wifi and Ethernet) from an infected device to prevent the spread of the attack. This action isolates the device and minimizes the risks to other equipment connected to the infrastructure. By interrupting the network connection, the attack loses its communication vector, thus limiting its scope.
Keep the device powered on preserves the digital evidence needed for analysis. Turning off a device can alter crucial traces, compromising the post-incident investigation. System logs and other temporary files may be deleted if the device is powered off.
Immediately inform the IT team allows for a swift response to the incident. The team can then assess the situation, implement isolation measures, and begin the analysis. Smooth communication with IT experts ensures a coordinated and effective response.
Quarantine the infected device to prevent compromising other systems. Continued use of an infected device can lead to the spread of additional malware. Isolating the device ensures that the attack does not spread to other segments of the network.
Quick communication with teams helps maintain vigilance and prevent further infections. Informing other departments helps limit propagation and avoid a secondary attack. Internal alerts strengthen security measures and prepare teams for immediate actions.
