Researchers hack Intel's vPro
- tptacek 18y agoThe break hasn't been published yet (it's a Black Hat DC talk), but it's very likely to be real, since Rutkowska is credible. vPro/TXT/LT is (for the most part) the trusted boot in the Intel chipsets. If you don't know about it, it's because nothing really uses it. It's a crypto coprocessor tied in very restricted ways with your CPU core. Its most important job is to allow you to run crypto-signed code blocks in a crypto-signed execution environment. In other words, it can boot a VM safely on a machine that's owned up with a kernel backdoor. If I had to bet on what this break generally involved, I'd say CPU synchronization on multicore systems.
