Anybody receives 16482:8 alerts from and
I've noticed if our inside user goes to the yahoo.com web site, it frequently generates 16482:8 alert.
I am thinking about put those addresses in the blacklist rule or block them on our FW.

The info I have suggests that this rule has a very low or zero FP rate, indicating that you are mistaken and that there are really some IE 6 and 7 browsers on your net. I'd suggest following up on the IP addresses to see what is going on.

Of course, it's possible that the alerts are being generated from browsers outside your network if you do not have $EXTERNAL_NET and $HOME_NET set up properly.

I recently installed Snort on my Ubuntu machine.    I am receiving a lot of 16482:8 alerts.  It is Microsoft ie 6 and 7 vulnerability alert.

I don't have any users who are on using IE 6 or 7.  What is triggering this alert?  Is this safe to ignore?
