I got hint to try out hidden data in dns traffic. That's not using any
of local proxy's ports and thus might stay unrecognized in log files.
Local proxy does only log proxy traffic coming in on ports
3128, 2121, 1080. There is no low-level 'packet-filter-logging'.

There is no packet capturing done. I like to call unsuspicious
traffic all traffic which don't go through proxy's ports 3128, 2121,
1080. e.g. hidden data in DNS traffic.
