>>>Rakshasa replaces the motherboard BIOS, but can also infect the PCI firmware of other peripheral devices like network cards or CD-ROMs, in order to achieve a high degree of redundancy.

Existent computer architecture gives every peripheral device equal access to RAM (random access memory), Brossard said. "The CD-ROM drive can very well control the network card." This means that even if someone were to restore the original BIOS, rogue firmware located on the network card or the CD-ROM could be used to reflash the rogue one, Brossard said.

The only way to get rid of the malware is to shut down the computer and manually reflash every peripheral, a method that is impractical for most users because it requires specialized equipment and advanced knowledge.

Brossard created Rakshasa to prove that hardware backdooring is practical and can be done somewhere in the supply chain, before a computer is delivered to the end user. He pointed out that most computers, including Macs, come from China.<<<
