## 1. The Intercept
|
|
Adversarial forces have deployed ground-based C-UAS laser dazzlers that track and blind friendly optical drones. The dazzlers are dynamically configured in the field using an infrared (IR) remote control running a customized NEC protocol.
|
|
|
|
## 2. The Mandate
|
|
We have captured an intact dazzler control board. The firmware uses deeply nested, dynamic conditional logic (`if / else if / switch`) to parse the raw hex codes from the IR receiver. There is a "Friendly Fire Lockout" code buried deep in the dynamic conditionals that permanently disables the dazzler.
|
|
|
|
You must step through the dynamic branches in GDB, trace the `CMP` and `BNE` chains, and reverse engineer the exact 32-bit NEC hex code required to trigger the lockout state.
