Hi Guys,

A friend of mine received this message supposedly from me in his hotmail account. Names/Email addresses have been changed but you'll get the idea

To :      myfriend () hotmail com
Subject : A good tool

This is a special good tool
I wish you would like it.

I know this looks like a typical Klez message but there are a few things that have me stumped.

1) The "my_name" email address is an old excite account which hasn't been used in over 2 years and has been disabled. The "myfriend" address was not in my address book at this excite account.

2) The return path is "my_name"@verizon.net

3) The source IP has been traced back to a prepaid account with an Australian ISP which doesn't require any personal information to register.

Obviously my email address has been spoofed and they've used a Verizon server to send it. Also included was a 112K Attachment called href.exe which I'm unable to access, presumably Hotmail has stripped it.

Anybody able to help me out with this one? I'm really just wondering if anybody has seen this before or if this is specifically targeted at me.

Many thanks guys..
