Passive components like a line conditioning resistor or cap could be changed out with an identical looking malicious component. Such a chip could perform effective MITM attacks against anything that talks on a serial line such as I2C, SPI, etc. This is pretty much a universal zero day for on board controllers, FPGA's, and anything that loads its boot code unencrypted. |
