From Wagner’s Weblog via Security Pipeline:
“Recent statistics about the volume of junk e-mail are so astounding as to leave any reasonable person gobsmacked.
A couple of years ago, it seemed astonishing when anti-spam vendors predicted that spam might exceed half of all e-mail. This week, e-mail security vendor FrontBridge said spam tops 93 percent of all e-mail by volume. The spam is driven, in large part, by so-called zombies, or PCs that have been taken over by hackers and turned into spam cannons.”
