As the world becomes increasingly dependent on digital infrastructures, the threat of cyberattacks targeting sensitive sectors is growing. In 2026, the FBI, in collaboration with the NSA, CISA, and several other American federal agencies, launched an unprecedented alert on a significant increase in cyberattacks aimed at fuel tank management systems. These devices, called automatic tank gauging systems (ATG), play a fundamental role in monitoring and managing gasoline stocks, but their cybersecurity remains largely insufficient against the tactics of modern hackers.
The supply of gasoline, a vital vector for transportation, industry, and daily life, could be seriously compromised by these malicious intrusions. Cybersecurity experts are sounding the alarm about attacks that not only disrupt distribution but also threaten the stability of critical infrastructures. This wave of imminent attacks, encouraged by technical flaws and outdated devices, highlights the urgent need to strengthen resilience against these digital risks.

Cyberattacks against ATG systems: a growing risk to gasoline supply
Automatic tank gauging systems (ATG) have become indispensable for managing fuel levels at gas stations, industrial facilities, and strategic infrastructures. Used in various sectors, these systems measure gasoline volume in real time, detect temperature variations, and identify potential leaks, thereby ensuring safety and supply continuity.
However, these systems present alarming vulnerabilities. The FBI and CISA recently revealed that nearly 900 ATG systems are exposed online, many without adequate protection. Some don’t even have passwords, while others use codes that are too simple, such as six-digit numeric sequences easily decipherable by experienced hackers. This lack of protection allows cybercriminals to remotely access equipment and then alter data on fuel volumes or tamper with security alerts.
The scenario may seem technical, but its implications are very real. Imagine a hacker capable of making it appear that the gasoline level is higher than it actually is or masking a detected leak, thus preventing operators from acting quickly. Such manipulations can cause a sudden break in the supply chain, paralyzing transportation networks and penalizing consumers and businesses dependent on this fuel.
Beyond operational disruptions, these cyberattacks pose an increased risk of major financial damage. Infrastructure operators must prepare response plans and secure their systems, as the cost of outages can quickly soar, not to mention the public safety risks in the event of an undetected incident.
The motivations and methods of cyberattackers targeting gasoline and critical infrastructures
Understanding why and how these cyberattacks are carried out is essential to assess their impact and respond effectively. Hackers’ motivations vary widely, ranging from simple demonstrations of power to sophisticated attacks aimed at destabilizing an economy or extorting ransoms.
A common observed method is exploiting vulnerabilities in the configuration of ATG systems exposed on the Internet. Without robust authentication, it becomes easy for a malicious attack to take control of fuel gauges. Once inside, hackers can:
- Modify fuel level measurements to mislead operators
- Disable security alarms, preventing detection of leaks or other anomalies
- Block fuel distribution by disrupting pump operations
- Generate false alerts to provoke disproportionate reactions and sow confusion
These tactics also often prepare ransomware campaigns, where hackers demand a ransom in exchange for restoring normal system control. The economic impact of such attacks can be dramatic, resulting in losses of several million dollars within hours, not to mention the costs related to regaining trust and restoring equipment.
From a geopolitical perspective, these attacks also threaten the stability of critical infrastructures. By paralyzing gasoline distribution, they affect population mobility, industrial production, and can exacerbate social tensions or even major crises.
Several recent cases illustrate the severity of this threat. In early 2026, a gas station in the American Midwest suffered a cyber intrusion. Hackers managed to manipulate the ATG system, displaying false fuel levels while deliberately slowing down supply. This sabotage caused a local gasoline shortage, triggering a rush to the pumps and tensions in the community.
In another context, an agri-food company using gasoline tanks for its logistics fleet was a victim of unnecessary leak alerts, causing a temporary halt in its operations. The costs generated by this failure quickly exceeded hundreds of thousands of dollars. The hacker also demanded an electronic ransom to restore normal control to the system, demonstrating cybercriminals’ effectiveness in exploiting vulnerabilities.
At the national level, coordination between various cybersecurity agencies has increased to limit these risks. The FBI has thus implemented information-sharing protocols with private actors to detect threats early. This cooperation has become an essential pillar to strengthen the resilience of critical infrastructures against attacks whose sophistication continues to grow.
Comparative table of attacks by type and impacts
| Type of attack | Method | Consequences | Notable example |
|---|---|---|---|
| Data tampering | Modification of displayed fuel levels | Fake shortages, distribution interruption | Midwest gas station 2026 |
| Alarm deactivation | Non-detection of real leaks | Increased risk of major accidents | Agri-food company 2026 |
| Equipment blocking | Forced shutdown of pumps | Total service interruption | Transport infrastructure 2025 |
Challenges of securing critical infrastructures against cyberattacks
Securing ATG systems, like many critical infrastructures, proves complex. Several factors explain this difficulty:
- Obsolete technologies: Many systems rely on old equipment, not designed to be connected to the Internet but now exposed without precautions.
- Lack of awareness: Some operators are unaware of specific risks related to these devices or lack the resources to ensure proper protection.
- Complex environments: The diversity of actors and technologies makes implementing a global cybersecurity strategy more difficult.
- High financial costs: Updating or replacing vulnerable systems represents a significant investment that not all businesses can always make quickly.
- Constant evolution of threats: Hackers continuously innovate, exploiting new vulnerabilities, forcing defenses to adapt permanently.
To face these challenges, federal agencies recommend specific measures, including:
- Setting up secure access with multifactor authentication for all exposed systems
- Conducting regular audits and penetration tests to identify vulnerabilities
- Training teams in cybersecurity and best infrastructure management practices
- Adopting a policy of constant software and firmware updates
- Close collaboration between government agencies and private actors to strengthen resilience
Beyond technical and security aspects, cyberattacks on fuel tank management systems have profound consequences in citizens’ daily lives and the overall economy. When gasoline supply is disrupted, several sectors suffer directly:
Transportation networks, especially road freight and public transport, experience delays or complete stops, affecting the mobility of people and goods. The agricultural sector is also weakened, as fuel supply is essential for agricultural machinery and food supply chains.
For businesses, a supply break can lead to considerable losses, whether it’s production line stoppages or increased logistical costs to work around difficulties. Finally, consumers quickly feel the effects through price increases or temporary gasoline shortages at gas stations.
Here is a list of particularly sensitive sectors:
- Road transport and logistics
- Manufacturing industry
- Agriculture and agri-food
- Emergency services and public safety
- Small businesses dependent on fuel
These impacts can translate into social tensions in the event of prolonged shortages and a notable economic slowdown, underscoring the vital importance of cybersecurity for critical infrastructures. Authorities thus insist that protecting these systems goes far beyond simple IT security, fitting into a national resilience strategy against growing cyber threats.
