Doesn't that contradict itself? If the attacker fakes the shutdown process (and/or the reboot process), how does a shutdown or reboot help if the process never actually happens?
- tholdem 3y agoSorry my reply was poorly written. Like with anything, there will be vulnerabilities and techniques that allow for verified boot bypass, which most are not trivial and which need to be fixed, but that does not mean verified boot isn't valuable and working. It means extra cost and work for threat actors and the example was just how it was once done, by not attacking verified boot, but the process before it. Maybe because true persistence was too hard to achieve at the moment, thanks to properly implemented verified boot. Once the battery runs out completely, then you can be sure verified boot is helping you out. I'm sure there are now other mechanisms that fixed the example of faking the boot process I wrote about earlier.
