  > Due to its emplacement on SPI flash which is located on the motherboard instead of the hard disk, the implant is capable of persisting in the system across disk formatting or replacement Lovely, so you’d have to reflash the firmware to fix it.

    I wonder if it could use the "no downgrade" flag (used on the vast majority of laptops) to block you from reflashing it. That would be hilarious.
