Exposed Industrial IoT Devices Enable Network Intrusions

Gas stations are falling victim to cyberattacks through exposed fuel tank gauge systems that lack proper security controls and network isolation. These Internet-facing industrial devices serve as convenient entry points for attackers to pivot into broader facility networks, potentially enabling operational disruption, data theft, or system manipulation. The attacks highlight the critical security gap created when operational technology (OT) devices are directly accessible from the Internet without adequate protection or segmentation from business networks.

Tactical Insight

Immediate actions

Conduct inventory scans to identify all Internet-facing industrial control systems and IoT devices
Implement firewall rules to block unnecessary Internet access to tank gauges and similar OT equipment
Change default credentials on all fuel monitoring and gauge systems

Long-term improvements

Establish network segmentation between operational technology (OT) and information technology (IT) networks
Deploy a secure remote access solution (VPN) for authorized personnel to monitor tank systems
Implement regular vulnerability assessments specifically targeting industrial IoT devices

Monitoring measures

Enable logging on all network traffic between OT and IT network segments
Deploy network monitoring tools to detect unauthorized access attempts on industrial systems
