== Introduction ==
Greasemonkey is a nice extension for Firefox that let you to "mod" the way
web pages look.
special comments at the beginning of it.

== The w0rm ==
I wrote a simple worm to show how this extension can be abused, all in few
lines of js.
It works in this way:
1) Hooks the onsubmit event with my own function
2) Scan for all textareas
3) When one is found it appends an evil link that should point to the worm
itself (in my example worm this URL is fake)
4) Submit all
5) If the current day of the month is 29 my funny payload activates :)
So if an user is sending something to a forum or a blog his/her post gets
"infected" with the evil link.
Infact to install a greasemonkey script you have only to click on the link
pointing to it (something like http://something.com/scriptname.user.js).
