Cookies and Your Browser History: Beware of Tracking and Hacking

As an internet user you probably find it convenient when a website loads quickly or auto-fill’s your credentials. It cuts waiting time in half and you don’t have to rack your brain for the variation of your usual password that you used for whatever account you’re on this time. Although you must appreciate the speediness, you probably won’t appreciate the fact that this compromises your privacy. Along with that, without a clear cache, you’re not viewing the most up-to-date version of the webpage, which can cause errors. Ultimately, tracking puts you at risk for hacking so clearing your cache and browser history regularly is an important way to increase your own internet safety.

Third Party Cookies

We’ve all seen them. Those pesky ads on the side of the website you’re browsing that show you all the things you would love to buy. How did they get there? You most likely clicked on a tracking link that uses cookies. Cookies are text files stored on a user’s computer which are acquired when browsing a webpage. These files hold very specific data that allows a website to identify and remember who you are. This data is sometimes sent to remote databases to be analyzed which allows sites to cater your browsing experience to you.

At the end of the day, you’re being tracked, and all this stored data is eating up your disk space. There are very easy ways to avoid being tracked by cookies in your browser settings. You can either edit their level of access or block them entirely. The more privacy the better.

History Sniffing

Another form of tracking related to your browser is, history sniffing. “History Sniffers” are not only the previously mentioned tracking companies looking at your online activity to target you, but they’re also cybercriminals customizing their online attacks to make you more likely to fall for them. They have a very simple system to follow. After you visit a website the color of the link changes. History sniffers look at these differences in color in order to compile a list of sites that you’ve visited. Then they time how long each visited site takes to load. The quicker the loading times the higher the likelihood that they’ve visited the site multiple times.

This information is useful to them for one very threatening reason. They then have the ability to send you malicious replicas of sensitive sites, like those that involve bank information. Before you know it, a cybercriminal will have access to all your bank records. Clear your cookies, cache and web history as much as you can. Try to do it once a week to get into the habit. Browser hygiene can dictate the safety of your cyber environment sometimes.


Another misleading benefit of cache is logging into websites. Most find it convenient that they don’t have to remember their Ticketmaster password the two times a year they want to buy tickets. Although seemingly easy, also very risky. There is a very simple way for cybercriminals to turn those dots that appear on your login page as your password, into the actual characters that are your password. You can do it to. Now right-click on the password box and select “Inspect”. This shows you the developer section with a bunch of code, and a highlighted sentence that starts with “input type=password”. Now delete the word “password” and hit the ‘enter’ key.

Now, when you’re already logged in you rarely see the login page but ultimately, you’re going to log out at some point. This is where the
cybercriminal comes in. Once the login page is available again your password will auto cash and with a few clicks the hacker has your credentials. A helpful tip is to deny browsers the right to remember your passwords.
