What we did
Decoded captured digital signals with a logic analyzer to recover the data carried on an embedded device's bus, and analyzed industrial-control-protocol traffic to understand and manipulate device commands. This is the layer beneath the application, where the device, the wire, and the control protocol live.
- Interpreting logic-analyzer captures to recover bus data (serial and clocked protocols)
- Reading and reconstructing embedded/firmware artifacts
- Analyzing ICS/OT protocol traffic to understand device command and control
Why it matters to a client
If your product is an IoT device, an embedded component, or touches operational technology, the risk is not only in the web dashboard, it is on the device and the wire. Very few application testers can work at this layer; combining it with web/API testing means one assessor can follow a flaw from the cloud all the way to the hardware.
