Websense┬« Security Labs(TM) has received reports of a new variant of an email attack that was originally launched early this year. The spoofed email purports to be from the Better Business Bureau (BBB). The message claims that a complaint has been filed against the recipient’s company.

Previously, the email attack contained an attachment that the victim would need to open in order to become infected. The new variant is slightly different.

The new message uses a tactic employed by other, more-successful email attacks, such as the recent Storm worm. Instead of including an attachment in the email, the body of the email contains a link to an external Web site from which the payload is downloaded if the link is accessed. This method allows the attack to bypass many attachment filters at the email gateway.
