Hello,

Some sophisticated malicious Cookies actually contain Spyware
But you block most of them anyway. I'll send you some more specifics in a pm. Thanks for bringing it up though.

edit: well incase it comes up again, thought I'd post it here rather than a pm:

What might happen if my web browser is exposed to a malicious script?

Among the possibilities are capturing your password and other information you believe is protected. You should also be concerned because malicious scripts can be used to expose restricted parts of your organization's local network (such as their intranet) to attackers who are on the Internet.

Attackers may also be able to use malicious scripts to infect cookies with copies of themselves. If the infected cookie is sent back to a vulnerable web site and passed back to your browser, the malicious script may start running again. Note: This is not a vulnerability in web cookies; rather, a malicious script takes advantage of the functionality of cookies.
