Re: Meet “badBIOS,” the mysterious Mac and PC malware that jumps airgaps

naive perhaps, though would it be possible to transmit such 'radio
code' via a small transmitter, say at short range in another building,
that could send a stream of infecting code into a building (and thus
the infection could begin outside the USB framework), such as via a
small programmed microcontroller with radio antenna, either networked
or running autonomously (or would this be a pirate radio issue,
closed-in on quickly by HAMs monitoring misuse of spectrum).

further, if this radio broadcast of code were possible, one-way or
bidirectional, what would prevent this from scaling city or region
wide if a transmitter were overtaken and sending out signals to
computers en masse, to reprogram firmware, targeting via equipment
statistics or OS/hardware demographics.

just wondering if software-defined radio may be a context for hacking
computers beyond the peripherals directly attached to the computers,
such that a different security situation, boundary, or perimeter may
exist yet not be accounted for or protected against.
