Warning - new trend of attempts to infect ISP users (possibly virus)
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 Subject: Email account utilization warning. Hello user of Elan.net e-mail server, Your e-mail account has been temporary disabled because of unauthorized access. For further details see the attach.

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?

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...

Sorry to tell you but this has been around for some time. I was the target - not a victim - of three of these letters since last year. Naturally I didn't believe it and warned my ISP what was happening. They have, since, updated their web page to reflect this but unfortunately haven't done the right thing and email the users. Greg.
