Debugging mechanism in Intel CPUs allows seizing control via USB port
https://www.scmagazine.com/debugging-mechanism-in-intel-cpus-allows-seizing-control-via-usb-port/article/630480/ Some Intel CPUs have JTAG over USB 3 debugging built-in. This could be good for debugging but is really bad for computer security. “starting with the Skylake processor family in 2015, Intel introduced the Direct Connect Interface (DCI) which provides access to the JTAG debugging interface via common USB 3.0 ports.” Having the DCI →
