God Mode Unlocked – Hardware Backdoors in Via C3 CPUs (2018) [video]

This isn't to say backdoors are implausible on modern processors (vulnerabilities in Intel ME/AMD PSP come to mind), but I would like to see some hard evidence before we panic and freak out. For now, "God Mode on x86 Processors" isn't something I will be losing sleep over, but I will cry about it into my beer ...https://en.wikipedia.org/wiki/VIA_C3
