First-party cookies are created from a website you visit. In e-commerce websites, it’s used to help users add more than one item to their cart. If the first-party cookie is disabled, every order added to the cart is treated as a new order.

Flash Cookies

Flash Cookies are a bit difficult to get rid of. It remains on the device even if other cookies are deleted. It is known as super cookies, which are independent of the web browser.

Zombie Cookies

This type of cookie re-creates itself once deleted. Hence, it’s hard to detect and manage like flash cookies. Zombie cookies are used on online gaming sites to prevent users from cheating. However, it can be used to install malicious software onto a user’s computer.

What Information Does A Cookie Store?

Cookies contain a string of text with information from the browser. The information it contains can only remember your browsing activities. However, there are some websites that store personal data. You can encounter such cookies on websites where you have provided your personal information. However, legitimate websites like banks and e-commerce often encrypt personal data to prevent usage by other parties who have access to your cookies.

These are some of the information cookies can store in their server:

  • Name of the cookie
  • Value of the cookie

Most people don’t like cookies. They immediately assume that cookies are all bad, it tracks every activities and information. However, it is crucial to remember that not all cookies are harmful. There are cookies that determine their safety. In fact, most websites won’t work well without enabling cookies.

However, there are cookies that can track behavior or activities online. Third-party cookies often collect the activities of users to provide targeted marketing.

You can disable cookies when browsing online. But see to it first that the website would work. As mentioned earlier, some websites require cookies to work.

When are Cookies Dangerous?

Cookies turn dangerous when in the wrong hands. Usually, data in the cookies don’t change and aren’t harmful. They aren’t able to infect computers like viruses, but when fallen into the wrong hands, they can cause harm.

When hackers gain access to these cookies, they’ll have the ability to track browsing histories.

One example of a harmful cookie is third-party cookies. These cookies came from another web page but can track other website activities. Often the cookies are generated from the ads on the particular site. Even though the user never clicked on the ad, it still gives advertisers and analytic companies the data they needed.
