The AMD Secure Processor is a CPU in your CPU you do not control. It’s a Trusted Execution Environment to protect VMs from host access or copyrighted work from distribution. At
#36c3 I will present our PSP hacking and how we regained control over it. https://fahrplan.events.ccc.de/congress/2019/Fahrplan/events/10942.html …Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -

We found multiple attacks on RCS, ranging from remote text message intercept to local MitM. Vulnerabilities lie in misconfigured deployments and the official Android messaging app. We present our attacks and how to fix them

Does AMD have something similar to the IFD for configuring flash speed and read commands? The PSP boots fine from the spispy emulator with normal 0x03 reads at 20MHz SCLK, although the x86 switches to fast 0x0B reads in PeiCore and reboots soon afterwards.pic.twitter.com/eYBTgFwuB4
