The implant was placed on the board in a way that allowed it to effectively edit this information queue, injecting its own code or altering the order of the instructions the CPU was meant to follow." Here is Bloomberg's layman explanation for how that snoop-chip worked: the component "manipulated the core operating instructions that tell the server what to do as data move across a motherboard… this happened at a crucial moment, as small bits of the operating system were being stored in the board’s temporary memory en route to the server’s central processor, the CPU. We've been covering BMC security issues for a while.

With the BMC compromised, it is possible the alleged spies modified the controller's firmware and/or the host operating system and software to allow attackers to connect in or allow data to flow out. If you can reach the BMC and its software, you have total control over the box. The BMC and its firmware can be told to power-cycle the server, reinstall or modify the host operating system, mount additional storage containing malicious code and data, access a virtual keyboard and terminal connected to the computer, and so on. It allows administrators to remotely monitor and repair machines, typically over a network, without having to find the box in a data center, physically pull it out of the rack, fix it, and re-rack it. The BMC is a crucial component on a server motherboard.

From what we can tell, the spy chip was designed to look like an innocuous component on the motherboard with a few connector pins – just enough for power and a serial interface, perhaps. The Bloomberg article is not particularly technical, so a lot of us are having to guesstimate how the hack worked. The surveillance chips, we're told, contained enough memory and processing power to effectively backdoor the host systems so that outside agents could, say, meddle with the servers and exfiltrate information. Those spy chips were not on the original board designs, and were secretly added after factory bosses were pressured or bribed into altering the blueprints, it is claimed. According to the report, tiny microchips that were made to look like signal conditioning couplers were added to Super Micro data center server motherboards manufactured by sub-contractors based in China. The reportįirst up, the key details of the exclusive.

So which is true: did the Chinese government succeed in infiltrating the hardware supply chain and install spy chips in highly sensitive US systems or did Bloomberg's journalists go too far in their assertions? We'll dig in.
