Symantec state of Spam September 2007

The September State of Spam Report is out and includes several interesting highlights and trends seen in August. Some highlights in this report include an update on the state of PDF spam, different variations that have been observed in e-card spam tactics, including fake YouTube sites, as well as insight into some new and novel tactics that were observed by Symantec during August.

Where did PDF spam go? Highlighted in a previous post as an emerging trend, PDF and other attachment spam reached a high in early August but closed out the month with record lows. First seen in June of 2007 with PDF files, attachment spam grew to encompass PDF, XLS and RAR files. By Early August, this spam type was seen in 20 percent of all spam, but by late August, accounted for less than one percent. Symantec will continue to monitor this trend closely for any changes.
