Because this is a brand-new Class of malware.
What is, Thunderstrike 2 or what I was referring to, Flashback? Because Flashback looks like a trojan installed via a Java flaw.
Thunderstrike. I was apparently not reading closely.
However, Thunderstrike (and I believe Thunderstrike 2) has already been patched months ago by Apple, in their OS X 10.10.2 Update. Also, apparently Macs sold after mid-2014 are immune.
By the way, there is a far more sinister fact that is completely glossed over here on Slashdot: These same vulnerabilities were first found in the UEFI firmware on "Windows/Linux" PCs. The "researchers" just wanted some notoriety; so, when they found the same vulnerability in Macs, they decided to develop a proof-of-concept for that platform and crow about it to the world. And BTW, "Option ROMs" are certainly not unique to Apple-compatible peripherals. Far from it. So, even if you don't use OS X, this exploit, or one very similar to it, can be coming to a computer on your desktop.
