Only certain cases have this ability, you have to check your specific model.

>>60429516
can you sign a ME firmware? no? Then make your own cpu and convince people to buy it

Ask Intel and AMD. They seem to know all about that sort of thing.

solder some transistors

why bother backdooring the hardware when there are 100s of 0-days sitting on some .gov server?

oh shit that's cool

How do the hardware backdoors work?

>>60429641
No.

That is wrong. And it is naive.

The real step 1 is to manipulate the VHDL/Verilog tools used to design chips so that compilation also adds a backdoor.

I guess everyone with half an interest in /sec/ knows about the compiler that was rigged for backdoors. This is the same idea, just for hardware.

Nice try NSA

Easiest way is to add undocumented functionality to the JTAG port or any one of the other ports/buses most modern chips are provided with such as
- I2S
- (S)ATA
- SCSI
- IIC
- audio
- camera

The NSA could point you in the right direction.
