Pen Test PartnersRelying on dual-homed devices to separate your networks? You might be opening the door to attackers without realising it. π₯οΈ
During a recent OT and ICS assessment, what looked like strong segmentation on paper actually created hidden pathways across their networks.
We found that dual-homed devices, combined with outdated firmware, default passwords, and exposed services, allowed bridging between different networks (often of varying trust levels).
This is a reminder that dual-homed devices are not a safe shortcut for proper network design.
