What's worrisome are the ones that survive a complete wipe and OS install. I hope Apple continues to harden it's products from those types of attacks.
That is feature of the updated BIOS design known as UEFI (all PC's and Intel Mac's use it), as part of that BIOS design that capability (install x after bootup from the UEFI/BIOS area) is there. Its interesting to note this updated BIOS design was pushed by Microsoft and Intel (2 great friends of the mass surveillance folks in the U.S. government) a couple of years after 9/11. Apple has to make sure only they can get updated UEFI images on your Mac is how it is secure - and one of the reasons there were alot of BIOS updates for Macs a few years ago.
You can see where it's been publicly abused by the Chinese PC vendor Lenovo (maker of Thinkpads) here:

This also makes sense why old school BIOS design's weren't liked by that professional hacking company that was hacked itself a couple of years ago - in their docs they mentioned they wanted PC's with UEFI BIOS's to attack implying old BIOS designs were more difficult.
