Warning! Accepting Cookies Without Checking This URL Detail Can Be Risky

It’s something we all do, often without thinking while surfing the web. A window pops up, we click “accept all” and move on. Though this quick validation has become a habit during web browsing, there are real stakes involved concerning the privacy of your data. Not all cookies are harmful, but not all websites are created equal either. Sometimes, a quick glance can prevent future problems.

Originally, cookies are small text files that help websites function properly and tailor to your profile. Without them, it’s impossible to stay logged into an account, maintain a shopping cart, or even have a site remember your preferences. This concept has been around since the 1990s, and today, it has become the norm, with no easy escape. As computer expert Cris Angulo mentioned to HuffPost, “cookies are neither good nor bad”, it mostly depends on the user’s choices and the website being visited.

The complication arises because there isn’t just one type of cookie. Some are relatively harmless, like those that disappear when you close your browser. Others linger longer to analyze you more effectively. Then there are third-party cookies, originating from external companies, often used to track your movements from one site to another. These are the ones that, for instance, enable targeted advertising based on your recent searches.

In this context, by clicking “accept all cookies,” you potentially open the door to all this tracking machinery. In some cases, this can go quite far. In practice, this means your searches, the pages you visit, or the time you spend on a site can be recorded, compiled, and used to create a very detailed profile of your habits. Computer researcher Roberto Yus puts it simply: “When you click ‘allow all cookies,’ you give the website carte blanche to install third-party trackers.” From there, companies can predict your future searches, influence what you see online, or even exploit some more sensitive information.

To avoid this, there’s a simple precaution: ensure the site you’re visiting is secure before accepting anything. This involves a detail in the URL: the little “s” behind “http.” This “s” means the connection is encrypted, which prevents third parties from easily intercepting the information you exchange with the site. Without this “s,” your data travels much more exposed, somewhat like being sent openly over the network. This doesn’t necessarily mean the site is malicious, but “your data is not protected”, laments cybersecurity expert Steve Weisman, thereby increasing the risks of banking and identity theft.

So no, this doesn’t mean you should reject everything outright. The idea is rather to sort through and favor sites you trust. For example, if you’re about to make a purchase on a site you’ve never visited before, taking a few seconds to check the address, the presence of a padlock, and the cookie settings can help avoid unpleasant surprises.
