On: When baby monitors fail to be smart

[_pmf_]

A baby monitor having accessible UART ports on the board has the same security implications as a PC having a CD-ROM drive.

Actually, considerably less.

[sokoloff → _pmf_]

Agreed on a stand-alone basis, but couple that with client certificate based auth and all client certificates being the same worldwide, and it makes the UART a convenient step in the chain of attack. (Agree that the problem isn’t the UART pads though.)
