The internet is full of bad actors. A nand.bin file is a full operating system image. If you download one from an unknown source, you have no way of knowing if it has been modified to include malware, corrupted system files that could permanently brick your console, or stolen user data.

A Wii NAND backup is a complete digital copy of your Nintendo Wii’s internal flash memory. This memory holds your system software, console-specific encryption keys, save data, and channels. If your system files become corrupted—a state known as "bricking"—a NAND backup is the only tool that can restore your console to working order.
A standard nand.bin file is approximately 528 MB (512 MB of raw NAND data plus ECC and metadata). The accompanying keys.bin file is very small (usually around 512 bytes).
