A couple of readers wrote about a flood of fake Amazon.com order confirmations they are receiving. The e-mail claims to originate from Amazon.com, and attempts to trick the user into clicking on a link which will then lead to obfuscated JavaScript and malware.

This particular attack appears to be a new version of similar e-mails we have seen over the last week or so. The new version uses larger e-mail messages, which appear to be composed with Microsoft Word.

The text is still pretty concise. As a sample:

-----
Dear Customer,

Your order has been sucessfully confirmed. For your reference, here's a summary of your order:

You just confirmed order #2341-23483720-38123

Status: CONFIRMED

-----

At the end of the e-mail follows a link to a malware site, labeled "ORDER INFORMATION".

A number of different domains have been seen used so far.
