Critical Infrastructure Alert: Is your fuel management system exposed?

The NSA, CISA, and federal partners have issued a new, urgent advisory regarding Automatic Tank Gauge (ATG) systems.

Malicious actors are actively exploiting internet-exposed ATG systems which are vital for monitoring fuel and liquid levels across the energy, transportation, and retail sectors. Unauthorized access to these devices poses a significant risk to operational continuity and safety.

Key Takeaways for Operators:

1- Audit Exposure: Ensure your ATG systems are not directly accessible from the public internet.

2- Harden Infrastructure: Implement strict access controls, use VPNs for remote access, and change default credentials immediately.

3- Monitor: Review logs for unauthorized access attempts.

Cybersecurity is not just an IT issue; it’s a core component of operational resilience. Read the full joint fact sheet to ensure your systems are hardened against these threats.
