NIMDA

One of the vectors was a web page redirect.

Not filtering any at this point... :(

As for .CHM

The BRITNEY virus is using this as a vector right now...

Subject: Question on attachment filtering


We are using Antigen 6.2 on our Exchange 5.5 server, with a set of filters
for risky file types.  We've been getting complaints from users about our
filtering of  *.htm attachments, and I'd like to get some advice on the
value of this filter, or risk of disabling it.  It seems a lot of our users'
business partners send them html attachments.  Trying to get them to change
their ways would be about as frustrating as trying to get the Bush
administration to prioritize the environment over energy revenue.

Couldn't a scumbag e-terrorist embed a virus in an html file, and send it as
an attachment that would get executed upon opening it, thus spreading the
virus?  

And while we're on this subject, if we do continue filtering *.htm,
shouldn't we also filter *.html and maybe *.chm?

What are you guys doing in your shops?  

Cheers,

- Bob

CHM is a must have.
HTM and HTML is a hard one. There have been times I have blocked them, but
only temp until we can get a virus def. I think that is going to be a hard
one to pull off.

Oh. It's a real virus. For some reason I though it was just as big a joke as
the singer.
