Around 80% of the Spam messages on the Internet are sent by Spam Zombies. For those who don’t know what I’m talking about, Spam Zombies are normal PCs that were infected by some malicious software and then controlled by some spammer.

The spammer then uses a backoffice to send orders to those infected PCs, or basically to send spam for living..


This nice post from pmontoya, shows exactly what such a backoffice looks like.
