        This technique can be used to write arbitrary files, i.e., the dump of one UDP packet.

        After starting Wireshark, and waiting for the capture to begin, deliver the UDP packet, e.g., with `nc` (see below). The capture then stops and the packet dump can be saved:

        1. select the only received packet;

        2. right-click on "Data" from the "Packet Details" pane, and select "Export Packet Bytes...";

        3. choose where to save the packet dump.

        PORT=4444
        sudo wireshark -c 1 -i lo -k -f "udp port $PORT" &
        echo 'DATA' | nc -u 127.127.127.127 "$PORT"
