Did they originally say it was a grain of rice Ethernet module?

I thought it was supposed to be an incredibly tiny micro sitting on the bmc's boot flash to break inject vulnerabilities.

I recall, at the time Bloomberg and their source were taking about tiny chip on the bmc that was masking as a resistor.

However they did not produce any concrete evidence, citing NDA between that security company and their client.

Even that makes little sense.

A malicious modification to the flash content would leave no physical evidence…
