nmap supports Zombie-Scan and also FTP-Bounce-Scanning.
And the -D Option should be helpfull too...
You should just care that the port dosn't transfere a lot traffic
(Zombi-Scan).
Another neat trick is passiv Port-Identification by simply just
sniffing the traffic. But you've to wait until somebody made a
connection.
If you choose the -T1 option for the timing: Generating a new valid
Mac-Adress every 5 Minutes is maybe also helpfull.
But this could be detected (but I never saw such a paranoid setting).
You maybe also wont scan with nmap because nmap-Scans are easy to
detect. And reducing the ports to e.g. just 3 or 5 (for one
scan-session, you can do serval and everytime a break between them)
would also help because then you can do a Full-Connect Scan to avoid
the Detection of SYN-Scans.
Just some ideas :-)
Kind regards,
Rembrandt
