We first talked about the using the UEFI firmware as an attack vector (At Def Con 22 in 2014). Since that time there have been three identified and disclosed versions of malware that directly targeted this critical subsystem. That would seem to be a relatively small percentage given the time since it was first uncovered, the number of devices that operate using the UEFI firmware subsystem, and the time between then and now. However, this is only ones identified and in most of the identified cases were found because of the method of delivery for the OS payload. This begs the question, are there more out there that just have not been found?
