I promised a fren here to provide a less jokey critique on this vid. Here is is:
At 2:10, he tries to connect to the URL alexeykapyshev.sputnik-v.ru. ssh (secure shell) response gives [127.0.0.1]:20000, 20000 is the requested port while 127.0.0.1 is always the local machine. It's his own laptop or PC. The name can be resolved by adding the name in the /etc/hosts text file (even Windows have that).
At 2:27. Once logged in, the other side starts a secure shell (console) session. The first line is telling:
Linux alexey-kapyshev-mcst 126.96.36.199-amd64 #1 SMP Debian 4.19.171-2 (2021-01-30) x86-64
Caption says "we are in the machine" and the response from the machine is the line above. "amd64" and "x86-64", so it's probably an AMD laptop, haha.
At 2:48, the sputnik-V-control command can be easily faked, it's just text. Even the "gathering info..." thing, those are also text and can be easily generated by a script, say a Python script which one can rustle up in less than an hour.
The info is copy and pasted from several sources. At 2:54, one can see the firmware line: PKQ1.180904.001. Look it up, that's an Android 9.0 firmware. So that may have been copied from his smartphone.
At 3:02, the CPU info appears. It's Elbrus, so that may have been copied from somewhere convenient. Specs matches Elbrus-2S+ Wikipedia info (500MHz & cache sizes matches). It's likely a workplace machine, because the ssh line has "mcst", or Moscow Center of SPARC Technologies, which is where they develop Elbrus.
The vacc info can be faked since it's just some text on his same machine (127.0.0.1). All you need is a flair for the dramatic to sell the fiction.
So it's just his own laptop and someone who has free time to do LARPing.
Elbrus-2S+ is 289 sq mm. On TSMC 7nm, it would scale to about 2 sq mm. Too big and too obvious. Of course it would be impossible to power the thing like RFID tags. UHF 915MHz toll tags that are batteryless don't have power for anything but a limited protocol to separate multiple responders. Not enough power to process anything, much less run Linux on a powerful chip with over 368 million transistors. Plus, UHF toll tags need a large (printed) antenna for power gathering efficiency and the UHF transponder is zapping it from nearby.
Nothing in the vid is credible. I would only sit up and pay attention if a credible news outlet that is consistently on our side (TGP or OANN) do a proper investigation.
