Especially considering how they gained this knowledge:
"Using vulnerabilities in Intel TXE we had activated undocumented debugging mode called red unlock and extracted dumps of microcode directly from the CPU. We found the keys and algorithm inside."
And looking further down, some X86 instructions (that people would usually call low-level) actually trigger execution of an entire ELF binary inside the CPU (implemented in XuCode). Just wow.
