MessageLabs announced the results of its MessageLabs Intelligence Report for March 2008. Analysis highlights that the prolific Storm botnet is responsible for 20 percent of all spam in the first quarter of 2008, with messages selling male enlargement drugs accounting for 41 percent of its efforts. In addition to spam, MessageLabs has intercepted more than four million emails from the Storm botnet since January containing links to malware or aimed at launching phishing attacks.
Other nostalgic events within the spam landscape this month include the appearance of stick-man art within a new image-spam campaign. The amateur-looking artwork, advertising the weight loss drug Hoodia, is the first of its kind and although the spam run looks the same, the images and subject lines frequently change in order to evade traditional signature detection.
MessageLabs Intelligence also highlights the change in the perception of social networking sites within the business environment with 11 percent of companies now blocking access specifically to Facebook compared to three percent who have pro-actively set up rules to allow access.
