ESCRIPTION
This frame should never be seen in normal TCP operation. Sometimes this is
done in preparation for a future attack, or sometimes it is done to see if the system
has a service which is susceptible to attack. A TCP frame has been seen with a
sequence number of zero and the FIN, URG and PUSH bits all set. To avoid this
attack include the above command.
