It's also going to need to connect to both SCK and SDA and 3.3V and GND to do anything on the bus.
Typical I2C topology only has discrete 10K pullups to VDD, can't do much with a 2 pin device that's in an 0201 package.
It's actually quite likely, if this chip/mod/hack whatever causes a problem, the board will be pulled and sent for repair. Of if the board comes in for something else and the odd part is noticed, when you look at these boards all day, something different sticks out. Someone's going to inspect that board and do some analysis to see if it's a problem that affects thousands of other servers. Once one chip gets found, the datecode printed on the board will identify the factory and production date. That would start a purge of all the boards and a major blacklisting of the manufacturer. None of the big guys (Foxconn, Wistron, Inventec, Quanta etc ) would risk it, the tracking would point right back to them.
Supermicro has the BOM, Schematics, Layout files, they , pre the article are not in on the hack and would be motivated to clear their name. If there is a chip inserted in between layers, you won't need a BOM to find that, no one does that on mass-produced serverboards, it's far too expensive.
Now, if there is a part that is nominally on the board, is part of the schematic and BOM , but has been replaced with a modified part, you wont find that on the paper work or even layout, you'll have to find a board with the part on it. I could see a reel of parts with the same footprint being substituted during a production run, but that means hundreds or thousands of boards are in the field.
Surely some Engineer or Tech has one of these in a box that had failed for an unrelated reason, or were part of an engineering test or even a spare. There are only so many parts that are potential candidates for substituion, ie ganged pullups on the I2C lines , a single 2 pin package wont be able to affect or read data, buffers or possibly a filter on the RMII lines from the BMC MAC to the management network PHY , filters or baluns on the PHY to RJ45 network jack, the jack itself. the BMC boot EEPROM all come to mind.
That's the problem with a hardware hack, it's going to leave a physical evidence trail. So far nothing has been produced. IMO this story is unraveling.
The one thing I've yet to see is one of these devices. If they got into the supply chain and made a production run of boards with these parts, there should be hundreds if not thousands of modified boards in multiple datacenters. Surely some engineer or tech has a failed or spare board in a box somewhere that has this part on it. If there was such a purge of servers once this became known, people would have talked by now, or someone would know and again have an old one or a lab board that they could pull this part off of. Getting into the supply chain at the board house is a single point, but the back end of where those boards went, that's hundreds of people.
As to where you'd put the device, another place would be between the management PHY and the BMC , the AST2400 otherwise connects to the Southbridge https://www.aspeedtech.com/pro... You'd not going to have direct access to the CPU there.
IMO a 'Plausible' hack, but until someone can produce one of these 'spy filter' chips, I'm not buying it.
I'd love to have Open Source firmware for my DJI P3, the hardware is really nice, but the restrictions and auto upload and forced updates by DJI are starting to annoy me. Sure, they're the biggest target and they'll do whatever the FAA asks to keep their market share. "Nice business there DJI, it'd be a shame if anything happened to it"

Far more likely, there's a bug in an interrupt handler that corrupts memory used by the throttle position servo. If they forgot to put a lock around a read-modify-write operation, it could get hit under unexpected operating conditions, that could be triggered by cosmic rays, ie a memory access exception handler routine.
The brake failure could be caused by the anti-lock system, but that's always a separate processor. Having that fail in a no-brakes mode, and the throttle fail in a wide open mode, seems really improbable since both sorts of failures are worst case and would imply some sort of interaction between the engine controls and the braking system. Those should be totally independent systems.

The biggest investors in several viable solar panel startups are the current oil companies.
Theres a few trillion$ worth of oil left, we've used about 1/2 of the cheap oil. They are smart, they arent about to leave that oil in the ground. It may only last 20years or less. Pretty fast considering it took 100 years to use up the first half.
And when oil becomes too expensive to waste by burning it to make electricity and run passenger vehicles, those same (now diversified) companies will be selling us photocell generated electricity by the kW or selling photovoltaic panels to the local utilities.
If you were non-ethical, at the time you decided to leave, but before you gave formal notice, you could do all those things you mentioned. Any non-ethical employee could do this at any time. Treating outgoing employees as potential criminals is a reflection on the culture of the company.

Here's an idea.. Put the GPS antenna outside of the metal airframe. RF gaskets on the doors and metallized glass windows and no RF gets out of the interior.
If aircraft systems are so sensitive that consumer FCC certified gear can take them down, then why hasn't anyone with bad intent brought up a 100W wideband noise source and glitched out the ILS or nav gear? Because maybe it cant be done? Any aircraft certified system is going to have strict requirements for out of band filtering. The antennas are placed on the top and bottom of the body, well away from the doors and windows where interior RF can leak out. The whole thing is more security theater and liability paranoia by the airlines. Some dope probably wasn't paying attention to the attendants when they told him how to buckle up because he was listening to a walkman and got tossed out of his seat in some turbulence and sued the airline for not telling him to put his damn seatbelt on.
If you're younger than 30, don't count on getting anything from SS or Medicare when you hit 65. Right now you're paying for all the boomers in the system.
The basic structure of Dynamic RAM has not changed, it still takes about 50nS for row precharge (Tras and 20bS column reads. All they've done is speed up the interface logic. The memory cell access is no faster. OK, so once you've opened a row, you can read that faster, but how many operating systems are optimized to keep the data row aligned in the system memory? You have a data request that is outside of the row you've opened, you have to close that row and open another, 120nS penalty. At 1.0GHz, that's 120 clock cycles.
Cosmic rays are basically high energy nuclei, which include essentially all of the elements in the periodic table; about 89% of the nuclei are hydrogen (protons), 10% helium, and about 1% heavier elements. They are accelerated to between 40% and 99% of the Speed of light, or between 100Million electron Volts to 10GeV, this must leave some sort of chemical or isotopic signature on things like organic molecules in ice cores. Sort of like the carbon14/12 ratio which is used to date formerly living things.
If the Cosmic Ray flux has changed substantially over a few thousand year period, there should be some way to test for it's effects.
I read that as ringing in the electrical signal. Possible caused by a ground on a coax cable working loose or maybe a component failing due to thermal cycling or cold stress.
The boards are built at room temperature, it's pretty cold in space if the sun isnt shining on something. Parts contract and if whatever they're attached to doesnt contract at the same rate, if can loosen things or even crack them over time. Qualifying parts for that sort of thermal stress is what makes things cost so much for Space Grade parts. It's also where they try to save money, only test 10 parts instead of 100 or only test for 10 day/night thermal cycles instead of 1000. It's always easy to say after the fact that they should use better, more expensive parts, but sometimes if you do, the mission goes over budget and doesnt get done at all.
