Of course the logs don't go far bag for me to tell - but i believe now that this was perhaps my less up to date laptop in power while away, as i mainly keep my main laptop up to date which i take with me. since that laptop isn't plugged in anymore, i will run a full scan on it next time - i believe the .34 address was for that device, but since the syslogs don't go far back enough i can't be 100% sure. Certainly no device right now or in my asus router syslog matches that ip. i appreciate everyone's help here - now i realize it may have been my less up to date laptop which somehow got infected when i was away, although i was running a firewall and an antivirus so hopefully those did something as well in terms of protection; but then it seems AI protection sees the device infection but i assume it blocked that outbound connection anyway; or maybe Skynet firewall in my router helped as well, who knows.
Yes it may have also been a false positive, who knows.
I did run a full AV scan and rootkins by several scanners on my current setup, nothing was found (but then again this computer was not even plugged in then).
