okay, so assuming the US gov can access my private LAN data due to my use of the Ubiquiti USG as router/firewall, USG wifi APs etc, of what form would this data exfiltration take? can we please explore/explain how this "compromise" would happen in real-life. if i were sniffing for outbound WAN traffic as root on the unix-like that the USG run, would i see the exfiltration traffic? or is this [supposedly/apparently] happening at a lower layer that an OS can't see i.e. some kind of BMC or BIOS layer? wouldn't such traffic also have to navigate the varieties/restrictions of DOCSIS etc? or are they also compromised? is the worst-case scenario here some kind of giant C2 network with waves hands tons of compromised lower-than-OS mini pieces of firmware exfiltrating data over waves hands compromised network providers hardware into the giant NSA AWS cloud?
