how to protect firmware from malicious persistent firmware/BIOS cracker
for over 2 months a malicious persistent cracker has laucnhed automated attacks against my computers.
1) for new desktop computes - then i have soldered togethber leg 3 and leg 4 together which should in theory protect teh BIOS from being flashed. But , will that also protect firmwaer VGA, ACPI, SATA, PXE and more from "Micro updates" of teh Biois code where cracker only replaces smaller parts of teh BIOS....or?
2) In my laptop computers (acer aspire 4755G and V3-471G) then there appears to be multiple "minor" fimwares that also hold firmware info for each specific part (like netcard or ACPI or USB or VGA card) - should i solder teh legs physically on each of those also to be protected from "micro code updating" of each indvidual firmware?
3) what tols can be used to check the individual firmwares for teh SATA, VGA, ACPI, PXE and so on so i can visually see/compare and confirm that the info stored is correct?
3) What software exist that can regualrly monitor against any scuh changes in firmware? Or, at least download manually the firmware codes so I can manually check it when manually laucnhed?
thank you for your kind help.
