Detect which process is attempting TCP connections

On my MacBook Pro (Monterey), I was looking at packet captures over a period of a few hours and I noticed that something on my box is, every few minutes, pinging other computers on the local network at port 7000 (sometimes my wife's work computer and sometimes my baby monitor). The recipients respond to the SYN packets with RST packets, so no connection is being established. Is there a way to set up some sort of watchdog which identifies which process/executable is attempting the connections when they occur?
