Over 900 US Gas Station Systems Exposed: Critical ATG Security Alert
Automatic tank gauge security has become an urgent concern after researchers discovered that more than 900 fuel monitoring systems across the United States remain dangerously exposed to cyberattacks. These vulnerable systems, found in gas stations and critical infrastructure facilities nationwide, represent a significant threat to operational safety and national security. For Australian organisations managing similar industrial control systems, this incident serves as a critical wake-up call about the importance of securing operational technology environments.
What Happened With These Exposed Tank Gauge Systems?
Security researchers have identified over 900 automatic tank gauge (ATG) systems that are directly accessible from the internet without adequate protection. These devices monitor fuel levels, detect leaks, and manage inventory at petrol stations, chemical storage facilities, and other critical infrastructure sites across multiple sectors.
The exposed systems lack basic authentication mechanisms, allowing potential attackers to access sensitive operational data or manipulate system configurations remotely. This vulnerability affects facilities ranging from neighbourhood service stations to large-scale fuel distribution centres.

How Does This Automatic Tank Gauge Security Vulnerability Work?
ATG systems are industrial control devices designed to continuously monitor storage tank conditions. They track fuel levels, temperature, water contamination, and potential leaks. When properly secured, these systems communicate only with authorised management platforms.
The Technical Breakdown
The vulnerability stems from several critical security failures:
- Default credentials left unchanged from factory settings
- Direct internet exposure without firewall protection
- Lack of encryption on command and control communications
- Missing authentication requirements for remote access
- Outdated firmware with known security vulnerabilities
Attackers exploiting these weaknesses could potentially falsify tank readings, disable leak detection alarms, or cause physical damage to storage infrastructure. The consequences extend beyond data theft into the realm of physical safety and environmental protection.
Attack Vectors and Exploitation Methods
Threat actors can leverage multiple techniques to compromise exposed ATG systems:
- Scanning for exposed devices using specialised search engines like Shodan
- Attempting default username and password combinations
- Exploiting known vulnerabilities in legacy firmware versions
- Injecting malicious commands through unprotected serial interfaces
What Are the Business and Safety Implications?
The ramifications of compromised automatic tank gauge security extend far beyond individual gas stations. Successful attacks could trigger cascading effects across supply chains and communities.
Operational Risks
- Fuel supply disruptions affecting transportation networks
- Environmental hazards from undetected leaks or spills
- Financial losses due to inventory manipulation or theft
- Regulatory penalties for compliance failures
- Reputational damage to facility operators
Critical Infrastructure Concerns
These systems fall under critical infrastructure classifications in most jurisdictions. Attacks targeting fuel distribution could disrupt emergency services, healthcare facilities, and essential supply chains. The interconnected nature of modern infrastructure means localised incidents can rapidly escalate into regional crises.
Australian organisations operating similar OT environments should recognise that these same vulnerabilities likely exist within local industrial control systems. Proactive assessment through comprehensive vulnerability management services can identify and remediate these risks before attackers exploit them.
Actionable Recommendations to Protect Your Systems
Organisations managing ATG systems or similar industrial control devices should implement these protective measures immediately:
Immediate Actions
- Conduct an inventory audit of all connected OT devices
- Remove direct internet access to industrial control systems
- Change all default credentials to strong, unique passwords
- Enable available logging and monitor for suspicious activity
- Apply firmware updates from manufacturers promptly
Long-term Security Improvements
- Implement network segmentation isolating OT from IT environments
- Deploy industrial-grade firewalls with protocol-aware filtering
- Establish VPN-only remote access with multi-factor authentication
- Conduct regular penetration testing of critical infrastructure systems
- Develop incident response plans specific to OT environments
If your organisation lacks internal expertise to address these concerns, speak with our security team to discuss tailored protection strategies for your operational technology infrastructure.
Frequently Asked Questions
What is an automatic tank gauge (ATG) system?
An automatic tank gauge is an industrial monitoring device used to track fuel levels, detect leaks, measure temperature, and manage inventory in storage tanks. These systems are commonly found at petrol stations, chemical facilities, and fuel distribution centres. When connected to networks, they require robust security controls to prevent unauthorised access.
How can I check if my industrial systems are exposed online?
You can use external scanning services like Shodan or Censys to identify internet-facing devices associated with your IP addresses. However, professional vulnerability assessments provide more comprehensive visibility. Look for any devices accessible without VPN connections, those using default credentials, or systems running outdated firmware versions.
Are Australian facilities at risk from similar vulnerabilities?
Yes, Australian organisations operating ATG systems and other industrial control devices face identical risks. Many legacy OT systems were designed before cybersecurity became a priority, making them inherently vulnerable when connected to modern networks. Australian critical infrastructure operators should conduct immediate reviews of their OT security posture.
Key Takeaways
- Over 900 ATG systems in the US remain exposed to active exploitation
- Vulnerabilities include default credentials, missing encryption, and direct internet exposure
- Successful attacks could cause fuel supply disruptions and environmental hazards
- Network segmentation and access controls are essential protective measures
- Australian organisations face similar risks in their OT environments
Conclusion: Prioritising Automatic Tank Gauge Security
The exposure of over 900 tank monitoring systems highlights the ongoing challenges of securing operational technology infrastructure. Automatic tank gauge security must become a priority for any organisation managing fuel storage or similar critical systems. The convergence of IT and OT environments creates new attack surfaces that traditional security approaches often overlook.
Australian businesses should treat this incident as an opportunity to review their own industrial control system security. Proactive assessment, network segmentation, and robust access controls can prevent similar exposures from threatening your operations. The cost of prevention remains far lower than the potential consequences of a successful attack on critical infrastructure systems.
