Mephisto is a mesh network of penetration testing devices, geared to attack wireless and wired devices on a target network. Each node of the network is one or more of: controller, router, extender, end node. End nodes can be tailored for a specific attack vector, e.g. MitM an ethernet endpoint or attacking 802.15.4 networks. End nodes will relay their findings back to the controller, where the operator may manually decide the next steps, or run a scripted attack sequence. Computation will be dispersed hierarchically based on available power and job load of each device. My goal is to allow even novice physical penetration testers to accomplish significant coverage over the networking/IoT portions of a physical penetration test. Novice to senior members who take part in red team/physical penetration tests will be interested in how this can make their job easier, and their work more powerful.
