Just now, I
opened up a Wired magazine online story
on hardware hacking through the supply chain, and was pleased – although not
surprised – to see that Monta Elkins of FoxGuard (who has been featured in this
blog at least a couple of times, most recently here) is the subject of the story, discussing how
he planted a $200 chip on a Cisco firewall to enable a remote attacker to
essentially gain control of the firewall.
The big
point of the article is that, while most people probably think a hardware
supply chain attack – as in the SuperMicro attack that was the subject of a Bloomberg article last year (which is
now the subject of a lot of doubt) - would require the resources of a
nation-state to pull off, it could be done by someone like Monta (not that
there is anyone like Monta, of course!)
with a miniscule budget.
But even
that isn’t the most interesting conclusion from the article. That is found in
Monta’s sentence that closes the article: "If I can do this, someone with
hundreds of millions in their budget has been doing this for a while." In
other words, not only could it be done at
scale by a number of organizations (mostly state-sponsored, of course), it
probably is being done, and has been
for some time.
Have a nice
day!

Monta emailed me to point out that "the $200 is including the tools/equipment, like a hot air rework station, that many hobbyists will already have. The actual cost of the implant is about $2." Of course, that makes this whole thing even more scary
