These real-world ICS and OT stories show how hidden connectivity, default credentials, shadow IT, and unsafe scanning practices can expose critical systems far beyond what organizations expect. From Iranian-linked APT activity and DNS-tunneling malware to broken segmentation and outdated equipment, the examples stress that visibility and careful OT-specific controls are essential. #IranianAPT #DNSTunneling #Solaris #WindowsXP #Fortinet #Tenable #NozomiNetworks #ZeroNetworks
Keypoints
- Standard IT tools can disrupt OT systems and even stop critical machinery.
- Attackers can move from IT into OT using tunnels, jump boxes, and persistence mechanisms.
- Default credentials and forgotten assets can expose “isolated” field control systems.
- Shadow IT, shadow SaaS, and unmanaged devices can create hidden OT risk.
- Continuous OT visibility and segmentation help reduce lateral movement and improve resilience.
