Modern browsers don't allow Javascript to be executed across multiple sites. If someone tried to code a bookmarklet like this to send the data anywhere else, it wouldn't work. The browser also operates in principle as a sandbox for Javascript. I can't write something in browser Javascript that will hack your PC.
