I understand what they are supposed to be, but how did Mike get his hands on them? And how does he know what he has are legit?
To go along with that, does he have anyway of proving these are legit captures? or is that what this is supposed to prove?
The problem with the pcap narrative is that government would need to be involved/admit to it in order to legitimize the claim.
That being said, depending on what the data consists of, could reveal quite a bit. I would imagine a coder/hacker would probably have their own program/daemon with its own communication protocol, and this infiltration would be small and custom.
However if it was done the newage way, it'd be "let's backdoor Teamviewer in and use that" or that could already be a "feature" as Dominion has done tech support via remote desktop before. If it is some sort of VNC/Teamviewer/RDP connection, then if you can decypher and refeed that stream/protocol I would imagine you'd essentially be seeing a videotape replay of what they did on their remote control.
