CISA warns of cyberattacks on tank monitoring systems

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning in conjunction with the FBI, NSA, and the U.S. Department of Energy regarding the threat of cyberattacks on Automatic Tank Gauging (ATG) systems. These systems are critical for monitoring fuel and liquid storage tanks across various critical infrastructure sectors. Authorities emphasize that these attacks could potentially have severe implications for national security and public safety.

The warning is directed at operators of tank storage facilities that may not have adequately secured their systems against cyber threats. ATG systems are often accessible via the internet, making them an attractive target for hackers. Authorities advise operators to review their security measures and ensure that their systems are protected against unauthorized access.

Risks to Critical Infrastructures

Attacks on ATG systems could not only lead to financial losses but also jeopardize supply security. A successful cyberattack could result in tank storage not being monitored properly, potentially leading to overfills or leaks. Such incidents could not only cause environmental damage but also threaten public health.

CISA has pointed out in its statement that the threat of cyberattacks on critical infrastructures has increased in recent years. Attackers are increasingly using sophisticated techniques to infiltrate and manipulate systems. Therefore, authorities are calling for enhanced collaboration between operators and security agencies to detect and thwart potential attacks early.

In addition to technical security measures, it is recommended that operators conduct regular training for their employees. These trainings should focus on recognizing phishing attempts and other social engineering techniques that often serve as entry points for cyberattacks. A well-informed employee can be crucial in preventing an attack.

Response from Authorities

The U.S. government has already taken steps to enhance the security of critical infrastructures. This includes initiatives to improve cyber defense and promote information sharing across various sectors. CISA has also provided resources to assist companies in improving their security practices.

The CISA warning is part of a broader strategy to strengthen the resilience of the United States' critical infrastructures. Given the increasing threats from cybercrime, it is essential for companies to take proactive measures to protect their systems. Authorities emphasize that the responsibility for security lies not only with governments but also with the operators themselves.

CISA and its partners will continue to monitor the threat landscape and keep the public informed about new developments. Authorities urge all operators of critical infrastructures to remain vigilant and regularly review their security precautions. Collaboration among various stakeholders is crucial to ensuring the security of critical infrastructures.

The warning about cyberattacks on tank monitoring systems was published on June 3, 2026, and is part of the ongoing efforts of the U.S. government to strengthen national security.
