What i would like to point out is that the bios battery is powering the bios, even if the pc is off.
Now obviously this is theoretical what i am going to say, BUT it would not be unthinkable that this bit of energy is enough to allow micro commands to be executed within the bios itself, for example wake up on LAN or similar options.
That being said i want to thank everyone for the additional info as some of it is new for me, so nice work.
But lets focus on the post i made, as so far there is no connection towards DARPA projects and such.
Obviously it seems that BADbios is using a similar technique then i posted. But so far did take the time to read up on BADb and its seems that it looks like it uses "some" techniques, but those who did read the report i posted will quickly find out that something way more advanced is being described in the report.
Nontheless BADb seems to be truly bad.
On a side note, cloud AV for BIOS is going to be a problem, because the BIOS is a integral part of the pc and of its start-up process and i do not see how within the current configurations this could be altered to have a reliable stand-off against BB Type malware or any malware for that matter.
Also the internal transport size of the BIOS chip and its very architecture needs a serious overhaul, otherwise it will never be capable to even service a AV solution.
However i could be wrong, just thinking out loud here
