But attack scope is limited....
Researchers have discovered what is believed to be the first in-the-wild rootkit that targets BIOS, the built-in software responsible for booting up a computer and managing communication between the machine and its attached devices.
The discovery of Mebromi is notable not because any widespread infections are anticipated – the complexity of a successful attack on the motherboard is high – but because it appears to be the first malware written for the BIOS in at least four years.
