The ThinkPwn vulnerability which has been in the news lately, which allows attackers to disable Secure Boot and bypass Virtual Secure Mode on Win10 Enterprise as well as disabling flash write protection turns out not to be yet another questionable Lenovo feature.  Instead the problem lies with the motherboards UEFI, specifically the Intel System Management Mode implemented on Gigabyte motherboards.  So far the issue has been located on Z68-UD3H, Z77X-UD5H, Z87MX-D3H, and Z97-D3H but it is possible that the vulnerability exists on far more motherboards, perhaps even beyond Gigabyte as the flaw is in the Intel code.  The Register also postulates this could effect HP Pavilion machines as they use these boards as well.


"Gigabyte has been swept into turmoil surrounding low-level security vulnerabilities that allows attackers to kill flash protection, secure boot, and tamper with firmware on PCs by Lenovo and other vendors."

For just under $200 you can pick up the Gigabyte Z77X-UD5H, a board that is a mix of high end and mid-range motherboard.  On the negative side [H]ard|OCP once again were disappointed by the performance of the mouse in Gigabyte's UEFI, not a big issue but very annoying when you are used to competitors implementations that don't force you back to the keyboard.  There were also a few aesthetic choices that [H] were not impressed by but the actual physical layout was done well.  As there is no PLX chip you will be best off using a pair of GPUs as the maximum which makes it a great mid-range board but misses the high end mark.  Check out how easy it is to overclock this motherboard in their full review.


"The Gigabyte Z77X-UD5H is a high end board with a mid-range price. Sound too good to be true? Well as it turns out it's still mostly a high end board with a few cost cutting measures here and there. The question I had to ask myself was: Is the Z77X-UD5H a high end dud or a mid-range marvel?"
