This is useful as it means that end users don’t have to even realize their EFI firmware needs updating and it will be done automatically when they update to the latest version of the OS.Another advantage of Apple bundling the EFI updates with the OS and security updates is that it provided us with a triplicate mapping between the particular model of Mac, the OS build version and the version of EFI that came bundled with that OS version.If not, remove any residual traces of past update attempts by opening the System Firmware Updates directory and moving any items in this folder to the desktop.Then try downloading the relevant updater manually from the Apple Support Downloads page and run it.Our research focused on the Apple Mac ecosystem as Apple is in a somewhat unique position of controlling the full stack from hardware, through firmware, OS, and all the way up to application software and can be considered widely deployed.This single stakeholder ecosystem made the job of gathering and analyzing relevant data for our research quite a bit simpler, however, we are of the belief that the main issues we have discovered are generally relevant across all vendors tasked with securing EFI firmware and are not solely Apple.In a nutshell, this means that attacking at the EFI layer means that you exert control of a system at a level that allows you to circumvent security controls put in place at higher levels, including the security mechanisms of the OS and applications.In addition to the ability to circumvent higher level security controls, attacking EFI also makes the adversary very stealthy and hard to detect (it’s hard to trust the OS to tell you the truth about the state of the EFI); it also makes the adversary very difficult to remove - installing a new OS or even replacing the hard disk entirely is not enough to dislodge them.

The second requirement is that the system needs to be connected to a reliable power source to install firmware updates.If the update still does not install, next try checking your boot drive for errors.

It decays with a half life of 5700 years into nitrogen 14 and electron and an electron antineutreno. So for that reason, every living thing that is interacting with its environment is expected to have this natural abundance of carbon 14. But when something dies, now it's not interacting with the environment anymore. We know that the amount at time t is equal to the initial amount times one half to the time over the half life, alright?… continue reading »
