Latest e-mail scam

"Chase Bank Online® Department Notice." This arrived in my in-box this morning, allegedly from Chase Online® Banking Department with copyright message © 2006 JPMorgan Chase & Co. It warns me that someone has used my account "from different locations" and that the bank must "open an investigation into this matter". Sounds very official; but. as I don't have an account with the Chase Bank, it is clearly a random mailshot from some criminal gang. The object is to make you visit the gang's website. Don't!
Some of these criminal e-mails also plonk spyware on your PC when you open the message. This one doesn't look too threatening: 3K, text only, clean-looking source code. It claims to have come from service@onlinechase.com, but the following line looks more truthful: Received: by mail.ricchio.net (Postfix, from userid 0).
Mafia, maybe?
