13:47 Erasing the information about the pages visited | |
| Security experts draw attention to one of the most familiar and natural functions of your browser: information on the visited link in your browser. As you know, after visiting the link, and reload the page link to change color. So, this information can be easily removed using a special script. The danger of such an attack is often underestimated. The site owner can easily see which links you have visited before. To this end, he may even specifically to introduce an invisible link on the page, removing information script. For example, it can check whether you went to the competitor's site, note this fact in cookies and even a change to your site content accordingly. Of course, this is a clear violation of privacy. And the more uncomfortable to know that private information about you is so easy anyone can learn. Mozilla developers have paid attention to this danger in 2002, but not figured out what you can do. Of course, there is no disputing the convenience functions for the user. In fact, we are all accustomed to it. In addition, site owners can apply imagination and to use a remote data acquisition from another browser for a better filter their content. For example, you can not put a button on some social networking sites, if the user has already moved on these links. But even in this case, the legality of such actions is questionable. In order to reliably defend against this attack, you can install a special plug-in for Firefox. | |
