I can’t believe that there is a person in the world receiving this who will not have received hundreds of versions of the same thing before, but the spammers continue. The malicious payload is at biggestloop.com/main.php?page=27f6207e33edeeca (analysis here) on 206.214.68.57 (B2Net Solutions, Canada). Block the IP if you can. Better still, write some filters for your email system to keep the things far, far away.
