I agree with the comment that the intention is not to exploit a the host, but as I stated earlier, I believe this was simply a port scan to determine which services may be running based on the ports that are listening. Although the attacker may have been attempting to determine the OS type based on the headers of the TCP response. The one thing that is for sure based on this trace is that the attacker would not have been able to determine the OS type because the victim host never replied back.
