From the explanation above, you'll observe that the data is still there. All that was tempered with are the links to the data they contain.

Today, web browsers aren’t used just for browsing the web pages; they’ve transformed into web applications—better known as Web apps. People use web services to upload videos, share photos, do online shopping, chatting and what not.

The web browser and the websites you visit always track and record these several types of online activities that you perform while browsing a web page or accessing a web app. We browsers store this activity data in the form of web history and cache files, and websites use cookies.

However, modern-day browsers can keep much more information than just browser history and cookies. Besides storing web history, a web browser can also store other sensitive data such as autofill form data, social media login credentials, online banking passwords, transaction details, saved credit/debit card details, and much more.

While the stored data such as browsing history makes it easy to quickly access the last visited site or a particular URL that you visited last week or last month, at the same time it makes you more vulnerable to hackers and also poses a threat to your privacy.

Here’s How!

You must have noticed sites saying they use cookies to improve the browsing experience. Basically, a cookie is a thin piece of information (.txt file) stored by websites in your computer/device to improve load time and overall user experience (by means of personalization). However, the same cookie is also used to track your online activities.

In fact, websites can track your online activity even if you log out of the site and never access it again; all because of the cookies stored on your PC.

While social media giants like Facebook claim to use cookies only to improve your ad experience based on your online activities, malicious sites can use the same to cause severe harm.

Besides, your system also stores the activity data in your local hard drive storage. If your laptop or storage media gets stolen or lost—which is entirely possible given the stats—the person who finds your device can quickly gain access to your sensitive data and information about your activities.
