Well if the attackers in cybercrime hack those cookies they can have access to your browsing sessions. And nowadays cybercrimes are spreading like forest fire. Here, the intensity of the dangers of cookies depends on where do they come.

  • Third-party cookies: The intensity of trouble is higher in this one. These cookies are generated by websites you are not browsing but are linked to the ads of that page. If you visit a page with 5 ads it will generate 5 cookies even if you didn’t click on the ads.

  • Zombie cookies: Even if the user has not opted to install the cookies, zombie cookies are permanently installed on user’s computer and generated from a third-party. You may delete them but they will still reappear. This type of cookie is really difficult to remove. They were first created from the data stored in the storage bin of “Adobe Flash” and that’s why they are sometimes called the “flash cookies”.
