Have you found instances of the actual virus in your emails or just
virus reports?  Because on of the features of netsky is that it spoof a
senders address as well.

As found out from the description of the virus from the above link

Hope this helps
Simon

With regards to the pop3 accounts - I didn't explain myself very well
(it is very hot here!)

Outlook on my PC has 2 accounts
1 setup to look at the exchange server internally.
1 setup to download mail from our other company's pop3 server (external
to my network) and store them in the exchange system, not a PST.

I have had bad mail delivered from the pop3 account into the exchange
server store and the desktop AV has caught it - this is definitely due
to the external mailserver not having AV and anti-spam software!
I'm guessing that this is a very bad setup (waiting for the comments!),
but I like my mail in 1 place and that's the exchange server!

Now I think about this, the user might need local admin priviledges to
do that - I have domain admin so I can cause havoc!

Hi Spence

Thanks for your reply.  No, we don't have any POP3 connectors running,
and no, we have no VPN access!  Any other ideas?!

Thanks for your time :o)


Sian.

Any home PCs/Laptops that VPN into the network?
Any users that get mail from other pop3 accounts and store the messages
on the exchange server?

People,

 

I'm being alerted to W32/Netsky-B worms trying to run in my domain.  My
workstation level AV is stopping the virus from running so it's not yet
a terrible problem.  However I'd like to know how these messages got in.
We've SMTP AV scanning at our gateway, and no sign of the message
passing through.  However the message is residing in the Inbox/ Deleted
Items of users mailboxes, with evidence of the unzipped file in
Outlook's temporary area.  I know this worm will spoof the address of
the sender, but surely I should still this spoofed 'From' address in my
gateway SMTP logs?

 

If anyone can explain how this may be getting in, I'd be extremely
grateful.

 

 

Many Thanks,

Sian.
