Spam Hits 95% of All Email
An anonymous reader writes "Commtouch released its Email Threats Trend Report based on the automated analysis of billions of email messages weekly. The report examines the appearance of new kinds of attachment spamsuch as PDF spam and Excel spam together with the decline of image spam, as well as the growing threat of innocent appearing spam containing links to malicious web sites. Image spam declined to a level of less than 5% of all spam, down from 30% in the first quarter of 2007; also, image pump-and-dump spam has all but disappeared, with pornographic images taking its place."
The link referenced in the posting goes to a summary page that is a little light on details. At the bottom of that page is a link to the PDF-formatted report. There's a lot more information there, including some screenshots of example SPAM and malware sites, trends in attack vectors, zombie systems, etc.. Interesting stuff.
