RE: Security problem in installation IE sp1 ?

["Wolf, Glenn" <glenn.wolf () we-inc com>]

That host is in Korea (note the port 25 banner time is also in KST).

APNIC only shows it as being owned by "Korea Network Information Center."

Use fport to verify this is really being initiated by ie6setup.exe.

Strange... but remember, anything is possible.....

Subject: Security problem in installation IE sp1 ?


Hello all


i found very strange thing when i install Internet Explorer SP1.

I'm download from www.microsoft.com/downloads/
ie6setup.exe install program. After download and start this program,
 install wizard start automatic download. I'm looking on the Firewall
 and ie6wzd.exe have open connection to any 62.54.250.120 server.
 Downloading was slowly and i haven't time. So i stop automatic
 installation. That is ok. But install program show message about
 canceling with messege (you must wait several minute .. bla bla.)
 I'm looking on my firewall again and i found very strange thing:

 program ie6setup.exe have open connection to IP 210.117.67.218 and
 port 8080 (probably any proxy).

 what is it ?

 i open scan to this machine :

* + 210.117.67.218   [Unknown]

                |___ ........#..'..$
