Cybersecurity and Energy Issues (1)

Energy has become one of the most sensitive geopolitical arenas. As states increasingly clash in cyberspace, energy infrastructure represents major strategic targets. It concentrates essential resources and determines how an entire country functions, and disrupting it can have immediate consequences for populations. For some fifteen years, state-backed groups have specialized in this sector, carrying out operations of sabotage, espionage or operational preparation. Winter further intensifies this vulnerability, because energy demand rises and flexibility margins shrink.

To understand the scale of the risks, we need to trace the evolution of attacks on industrial systems and analyze how hostile actors exploit states’ energy dependence.

Origins of Energy Hacking

The modern history of energy cybersecurity begins in 2010 with Stuxnet. This extremely sophisticated malware specifically targeted Siemens programmable logic controllers used in the centrifuges of Iran’s nuclear program. Unlike conventional cyberattacks, Stuxnet’s aim was not to steal data but to cause physical damage, by manipulating the speed of the centrifuges while masking the resulting anomalies.

Its characteristics laid the foundations of modern industrial cyberattacks:

• Perfect knowledge of the systems
• The ability to modify physical parameters.
• A logic aimed at material degradation.
• Persistence
• Discretion

This attack revealed that physical infrastructure could be sabotaged remotely, without missiles or explosives. Since then, the boundary between cyber and the physical world has become porous.

Ukraine: The First Power Outage Caused by a Cyberattack

In 2015 and then 2016, Ukraine’s power grid suffered two major attacks. Attributed to the group Sandworm, described as an elite hacker group belonging to the Russian army, they were the first large-scale power outages deliberately caused by a digital operation.

These attacks showed that it was possible to:

• take control of control centres
• manipulate distribution interfaces
• cut off power to hundreds of thousands of users
• simultaneously coordinate technical sabotage and disinformation operations.

Western operators understood that their own networks, often old, interconnected and partly automated, were exposed to the same risks.

Triton/Trisis and Functional Safety

In 2017, the Triton (or Trisis) attack targeted a petrochemical plant in the Middle East. The malware targeted Schneider Electric functional safety systems, designed to protect the facility in the event of a failure. The attempt was serious, because compromising these systems could have caused an explosion and significant loss of life.

This attack marks a turning point:

• Attackers no longer seek only to disrupt, but to cause an accident.
• Mastering the inner workings of a safety system requires a very high technical level.
• Sabotage can target the very protections that prevent an industrial disaster.

Triton remains one of the most dangerous attacks in the history of this type of hacking.

Colonial Pipeline: An Attack That Paralyzes Operational Technology

In 2021, the DarkSide ransomware paralyzed Colonial Pipeline. The attack did not target industrial systems but administrative IT systems. Even so, the company shut down its pipeline network as a precaution.

This crisis revealed several realities:

• An IT attack can have a massive impact on infrastructure.
• The lack of clear separation between IT and operations is critical
• A simple financial compromise can cause logistical chaos.

The lines at gas stations, the temporary price spike and the government reaction showed the extreme sensitivity of energy supply chains.

A Massive Increase Since 2022

Since the start of energy tensions in Europe in 2022, intrusion attempts against critical infrastructure have exploded. The most targeted sectors are:

• methane distribution
• high-voltage networks
• gas transport systems
• offshore pipelines
• maintenance companies
• management centres

Groups are notably multiplying attacks that allow stealthy initial access, seeking to maintain a discreet presence until a geopolitical situation makes a visible attack opportune

The most active groups include:

• APT33/34 (Iran)
• Sandworm (Russia),
• Berserk Bear and Dragonfly (Russia),
• Lazarus Group (North Korea)
• Red Echo (China).

Their strategy combines espionage, preparation, potential disruption and sometimes manipulation of industrial parameters. This type of attack is called an APT (Advanced Persistent Threat), and combines a very high level of technical sophistication, able to stealthily penetrate the critical systems of large organizations (companies or institutional actors) and remain there persistently (dormant for long periods).

Why Energy Has Become a Prime Target

• Energy infrastructure is one of the symbols of a state’s sovereignty. Destabilizing it is therefore a strong political act.
• States are often dependent on external resources, and must deal with other states to meet their needs, which further increases their vulnerability.
• Winter is the most critical time for continuity of service.

A well-coordinated attack can cause:

• pressure on the government
• loss of public trust
• logistical disruption
• political escalation.

Energy is no longer a resource: it is a strategic lever.

The past fifteen years have shown a continuous escalation in this field, which is often poorly understood by the public. The energy sector has become a digital battlefield in its own right. APT groups use winter as a strategic opportunity to maximize impact. Understanding this threat is essential to answering the question we will address in our second part: how do we guarantee continuity even in the event of an attack?
