It gives a quite good summary about Starlet in the Nintendo wii Broadway IC.

Either the writer of the article made a mistake, or they just simply try to broaden/simplify the message to reach wider masses .

Either the IC can be in the semiconductor , or they can insert during the packaging of the IC (the IC is on a small PCB , with many resistor / other component, it is visible on the old Intel /AMD CPUs without taking them apart)

It is possible to attach an IC to the JTAG port of the motherboard.

IF the attacker know the JTAG hierarchy/registers and so on then with four wire he can get out any information from any machine.
That can be a small IC with only four wires.

However example the JTAG of the Intel CPUs is a black hole, no one know anything about them ( apart from the two JTAG legs on the CPU) outside of the intel.

So now you saying spy chip mounted on CPU instead on the motherboard!


Come on now, CPU nowadays are flip chip meaning all their signals are underneath attached to motherboard,

There's vno signals on top, only heatsink.

So, how can another chip attached to CPU??

So now you say article makes mistake. Well it makes no sense at all technically.

It's purposes is fool people with no technical background. And the target is politicians with no technical background

That's why Apple and Amazon refused it.

US media has no real technical people work for them except half baked cut and paste people, fetching info here and there.

DHS says no reason to doubt firms' China hack denials

WASHINGTON (Reuters) - The U.S. Department of Homeland Security said on Saturday it currently had no reason to doubt statements from companies that have denied a Bloomberg report that their supply chains were compromised by malicious computer chips inserted by Chinese intelligence services.

There are many test point on the motherboards.
And the JTAG is the most important of all, usually that has pads/thought holes, even with same marks.

So, it is possible to control practically any electronics through the JTAG ports, but it require extreme level of knowledge ( on the same level like the designers /tester of all key ICs on the motherboard.)

Let's assume JTAG, two signals + power and ground for a total of 4 traces going to Spy IC now
1) motherboard needs a SPY IC footprint onboard to accommodate that IC. That means original motherboard design have to consider that.
That doesn't make sense.

2)article says Spy IC is pencil tip sized. Now 4 traces of motherboard going to tiny IC. How does that fit??
IC is too small mechanical to grab a hold of 4 traces from motherboard

Again, it makes no sense either motherboard or on CPU.
