Quite different really.  FIREWALK is really an intercept device to get
data out of a firewalled or air gapped network.  The exploit Bloomberg
describes would modify or alter data going across a server’s bus.  The
big difference is the Bloomberg device needs command and control and a
place to dump the tapped data to over the server’s network
connection.  That device is not going to be able to do so out of any
classified military network I have ever worked on.  Or anyone with a
halfway decent firewall (which I would assume Apple and Amazon would
have for the internal servers).  I think this article is unlikely to
be true for the following reasons :

 

1.       Separate chip is much more detectable physically than an
altered chipset that is already on the board.

2.       Requires motherboard redesign to get access to power and
buses needed (again easily detectable during any design mods “hey does
anyone know what these are for?”)

3.       Does not have onboard communications so it will be sending
data traffic on the network interfaces (will definitely trigger even
the most rudimentary IDP systems).    It relies on these backbone
Internet companies and Intelligence agencies to have absolutely
abysmal security on their networks to be at all useful.

4.       Parts would have to be brought into the plant, stored
somewhere, and all the internal systems would need a trail of  where
the part came from, how ordered it, where it is warehoused, loaded
into pick/place, etc.  Much better to compromised an existing chips
supply chain.


Whatever the truth here, I'm sure that the article as it is written
isn't telling us everything. There's more to this than meets the eye
including, quite possibly, the full facts about how data would be
exfiltrated and/or, perhaps, exactly what was done to the customers'
hardware.

Does anyone think that someone somewhere is trying to kill
Supermicro?  They sure have had a lots of bad news lately.


Who knows. Perhaps we are intended to come away with certain impressions.
