Intel SMI Transfer Monitor (STM) for SMM

2009: we present "Intel TXT bypass w/ malicious SMM", Intel responds: "STM" is the solution,
2015: the STM spec actually is published 🙂

. @coreykal So… that means we can actually expect widespread STM impls around 2018! And a BH talk about attacking these around 2019 😉

If you want hypervisors to not be inherently pwnable by SMM, you need STM! Ask your Doctor/BIOS maker if STM is right for you 😉

6 years after ITL first mentioned it, the doc for the tech necessary to make Intel TXT secure is finally public! 😀 https://t.co/P0n3vAwjq5
