Yo you can tell in his voice from the start that this is going to be good

[@alexstixx]

Wow what an absolutely incredible exploit. Thank you for sharing this DefCon!

[@ickromwerk610]

Have you tried to look for already existing back doors?

[@thewhitefalcon8539]

well they found one where "IN AL,DX" resets microcode to default!

[@willemvdk4886]

They had me at the demo when they popped three calculators. Holy crap

[@Irongrip62]

@4:18 Wasn't all of Intel's shit leaked recently? As a security researcher, why wouldn't you look at all the leaked VHDL and microcode source code?

[@ryjelsum]

they may have, but legal precedent demands that they construct a reasonable method by which they could have discovered the issue at hand without protected intellectual property when talking about this in the open :)

[@custom5331]

God damn, you got some CHEDDAR! Great job, good luck!

[@danielnielsen24]

Great talk!
