<h1>Reverse Engineering IoT Firmware: SPI Flash Extraction</h1>

<p>
|
||||
In security audits of embedded systems, retrieving the firmware is usually the critical first step. When over-the-air updates are encrypted and the debug ports (UART, JTAG) are disabled in production silicon, dumping the physical SPI Flash memory chip becomes necessary.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
In this write-up, we extract firmware directly from an 8-pin SOP SPI flash chip using a Bus Pirate. This hardware-level approach bypasses any bootloader lockdowns and extracts the raw partition table directly from the silicon.

||||

After standard verification, we can proceed to unpack the bin file using tools like <code>binwalk</code>. If the partition table contains standard filesystem formats (e.g. SquashFS, jffs2), binwalk extracts it automatically. Otherwise, manual offset carving is required.
