Malware Writers Using HTML Email Exploits to Spread Trouble

This from PC World:  Malware writers are turning to SPAM to distribute their software exploits.  Please read the PC world article at the above link for more details.

The mail contains an HTML attachment with a JavaScript component that, when clicked on by an email reader, can send you to web sites selling everything from pharmacy prescription medications to fake anti-virus programs.  Often these programs install a backdoor Trojan so your machine can be accessed from the web without you knowing, and then scanned for identity and financial information or added to a bot-net for spamming or denial or service attacks.

Some of the emails are designed to look like an undeliverable mail announcement, in an attempt to more easily deceive recipients into clicking on the malicious link or attachment.

Spam filtering provided as part of your Internet Security Suite or as part of MS Outlook 2003, 2007, or 2010 can help block these attacks.  Third party spam filtering from your email service provider, or products like Barracuda or Postini can also be effective.  The best defense is simply to NOT CLICK ON AN ATTACHMENT OR HYPERLINK in an email unless you know who it is from and you were expecting to receive it.
