it has gotten to the point for me that i am looking for a whitelisting option on my firewall/a-v gateway instead of a blacklisting one for attachments.

Erm is it me or are the writers of Bagle and Netsky determined to keep morphing their code to outwit the virus scanners.. is this a new trend in virus writing - beat the systems by evolving your code quicker than the security firms can release updates?

new trend in that it started only a decade ago?


Perhaps I'm only following this as its affecting us more, but I dont recall a time previously when I've had so many viruses hitting us and getting thro our scanners with nothing we can do about it. I dont recall seeing viruses with variants as high as 'j' before, especially in the relatively short time since the previous variants were out

Seriously, drop some references if I'm off-track.. its just my perception and I'm not an expert at all with viruses...

I have just seen emails (several different kinds) pretending to be sent
from 3 of my isp domains to users of those domains warning users that
their email account would be disabled and asking to open a .pif
attachment. I know largest ISPs probably have expierenced this but I
believe what I  have seen today means they are after ISPs (or possibly
just after any  domains with number of email addresses under them) of all
sizes right at  the moment. All emails we received from the same source
ip - 129.59.206.187 Please check your email base for what looks like the
following
(in the examples I changed everything to elan.net, actually every isp
domain received different example of this, only first one is exact).

Example 1:

From: management () elan net
To: xxxxx () elan net
