RE: Strange UDP Activity

[Rajiv Dighe <rdighe () SANDVINE com>]

Port 1067 is also used by Installation Bootstrap Protocol Server. Apparently
on default win2k server install this port is utilized. details are available
at http://support.microsoft.com/default.aspx?scid=kb;EN-US;q289241

This could be an attempt to map out hosts running win2k servers in default
install. This is apparently also used by HP boxes. i.e. you can setup one
box to act as software installation server. So looks like this is not
limited to windows world.

Subject: Strange UDP Activity


Greetings to the List,

I recently started seeing strange UDP traffic to my home DSL, which is
included below. It has been active for the last 4 days at all hours. None of
these IPs are DNS servers that I use, and much of the activity is when all
of my computers are off. Google led me to port 1067 as being an SNMP port,
but I have SNMP disabled on all devices at home, and the ACL blocks it
anyway.

Is there a new vulnerability going around that I missed? So far I have not
read anything on the list that looks like this...any ideas?

Thanks for listening,

Mike
