Update to Cybersecurity Advisory: DOE Threat Memo on Nationwide Cyberattacks Targeting Automatic Tank Gauges (ATGs)

Update to Cybersecurity Advisory:
DOE Threat Memo on Nationwide Cyberattacks Targeting Automatic Tank Gauges (ATGs)

Wednesday, April 29, 2026 – In follow-up to cyberattacks on automatic tank gauges (ATG), DOE has developed a threat memo and asked that we share the memo with marketers to assist in the prevention of further successful attacks. Attached here is the DOE Energy Threat Analysis Center (ETAC) Threat Memo on ATG Manipulation by Malicious Cyber Threats.

EMA was first alerted to the attacks by the Tennessee Fuel & Convenience Store Association (TFCA) earlier this month. EMA and TFCA subsequently worked with DOE Cybersecurity, Energy Security and Emergency Response (CESER) and DHS Cybersecurity and Infrastructure Security Agency (CISA) to coordinate mitigation efforts and communication. The ETAC Threat Memo is the DOE follow-up on the reports.

These incidents are exploiting very basic cybersecurity deficiencies, and organizations that have this problem may also have vulnerabilities in other systems/equipment. EMA urges its members to take advantage of the DHS Cybersecurity and Infrastructure Security Agency (CISA) no-cost services to shore up cyber deficiencies at No-Cost Cybersecurity Services & Tools | CISA.
