Does this also come with an increase in surface attack from malware?

  Don't believe the FUD. UEFI does not increase attack surface. It reduces it through means such as secure boot. The other option is insecure booting with no verification, and if your malware is running with privileges to be able to inject itself into the boot process, the machine is already compromised anyway. In this case secure boot provides some means of protection. People not using UEFI however, they are vulnerable and most likely affected.

    I would argue that, taking Secure Boot as a given, the UEFI design provides an amazingly large surface which to attack Secure Boot.

      Unless you're arguing for something new and different, the only other option you have to UEFI secure boot, is completely unverified boot which provides zero security. And that has to be less secure than UEFI by definition. In that regard arguing about how UEFI brings attack surface seems misguided. Yes, there's is an attack surface, but that's only because now there is something to attack where there previously was a fully open door. What you're saying is pretty much that any imperfect security measure lessons security compared to no measure at all, because it brings attack surface. That's a fairly backwards way of thinking.
