Reverse Engineering Hardware and Firmware

Why reverse engineer

Reverse engineering is how you understand a system you did not build. Whether you are documenting a legacy board, checking a competitor, or recovering a design with no schematics, the goal is the same: turn a physical object back into knowledge.

We approach it in two layers — hardware and firmware — and cross-check one against the other until the picture is complete.

The hardware layer

It starts with a teardown: photographing, probing, and identifying every part. Component markings, pinout tracing, and signal measurement rebuild the schematic, while removing layers from a PCB reveals the routing where markings fail.

Good notes matter more than expensive tools. A methodical log of what you found, where, and how it behaved is what turns a teardown into something reproducible.

The firmware layer

Firmware is read out, disassembled, and mapped. Identifiers, strings, and interrupt tables give structure; tracing data flows through the code reveals protocols, control loops, and hidden features.

The result is a documented system — schematic, behaviour, and interface — that you can maintain, modify, or re-create with confidence.
