Subject: TCP Port 42 port scans? What the heck over...

http://isc.sans.org/port_details.php?port=42&repax=1&tarax=2&srcax=2&percent=N&days=70&Redraw=

Shows a fairly large spike over the weekend. 42 is used for WINS (MS's
netbios name server) replication, and recently the Immunitysec folks
found an exploitable bug in the WINS service. Still, given how few
people one would expect to have that port accessible through a
firewall, or just how low the percentage of windows servers running
WINS is, it is somewhat of a strange target if it is indeed an
attempted WINS exploit.
