If they can write to it, then they can read from it. There is no distinction or security control. There will also not be a trace on the client side that anything has happened. Additonal testing with Opera and FF2 show that they do not block/prompt for this behaviour by default. So you can't make the statement that nothing happend with FF.

Annoying to have your clipboard contents clobbered, but not really a threat. It didn't do anything in FF2. -s On Thu, 15 Mar 2007 10:15:53 -0400 <jay.tomas () infosecguru com> wrote:
"TinyURL.com Making long URLs usable! More than 29 million of them. Over 700 million hits/month." Word of warning. When you submit a url to be shortened by tinyurl.com they attempt to steal the contents of your local clipboard. IE7 intercepts this and ask whether you want a site to be able to access your clipboard or not. Not sure how IE6, Opera and Firefox behave. Sent an email to inquire about why they were trying to access. No response as of yet. Jay
