EMA
Tuesday, June 2, 2026 – The Cybersecurity and Infrastructure Security Agency (CISA), in coordination with the FBI, NSA, EPA, DOT, and other federal agencies, has issued an advisory warning of active malicious cyber activity targeting automatic tank gauge (ATG) systems at fuel storage facilities across the United States. Federal agencies have observed threat actors exploiting internet-exposed ATG systems to gain unauthorized access, execute commands, alter tank parameters and pump controls, disable system alerts, and create conditions that could mask leaks or cause physical damage to tank infrastructure.
Per the advisory, EMA urges marketers to take immediate action:
- Remove ATG systems from public internet exposure — use firewalls, VPNs, or access control lists for any necessary remote access
- Change default passwords immediately and implement strong, unique credentials with multifactor authentication where feasible
- Apply available security patches in coordination with certified ATG service providers
- Monitor networks for unauthorized access and report suspicious activity to CISA at report@cisa.gov or 888-282-0870
