The Email Cluster Bomb
E-mail cluster bombs are massive e-mail attacks that can easily be performed by impersonating the victim and subscribing him/her to a huge number of Web services (newsletters, advertisements, etc).
The purpose of this site is to disseminate information about the e-mail cluster bomb attack and the simple solution we devised to prevent such attacks. We illustrate the attack, the vulnerability of sites, and the solution with a number of simple demos.
