How your browser is spying on you: Hidden dangers lurking behind every click

A browser is one of the most popular apps we use. It’s the gateway between the internet and its users, translating raw code into something we perceive as a web page and allowing us to interact with the web. It’s safe to say that anyone who uses the internet uses a web browser. 

But while this tool is extremely useful, it can also be equally dangerous. For example, clicking malicious links can redirect you to harmful websites that either steal personal information or infect your device with malware.

If you use a search engine like Google through Chrome, it can collect data on your searches, browsing history and even your location (if location services are enabled). Most browsers also use cookies, small files that store information about your online behavior. Let’s discuss the risks associated with web browsers and how to stay safe.

How a browser doubles as spyware

Browsers are much more than simple tools to navigate the web. They are, in many ways, tools for surveillance. While they help you access websites and services, they also track your every move online to feed the ever-hungry advertising industry.

First off, most browsers collect data about your searches, browsing habits and even your location. This data isn’t just stored to “improve your experience,” it’s used to create a detailed profile of you, which is then shared with advertisers who target you with personalized ads. 

Google Chrome, for example, is notorious for tracking your activity. As you browse, it feeds data to Google’s advertising engine, allowing it to serve highly targeted ads based on your behavior. This includes everything from your search history to the websites you visit, even down to the smallest detail, like how long you stay on a page​.

“Google may share information about you with advertisers, business partners, sponsors, and other third parties,” Google boldly mentions on its privacy policy page.

Browsers also use cookies to keep tabs on you. These cookies track your activity across different sites, even after you’ve left a site. This means that ads you saw on one website might follow you across others, creating a persistent digital footprint. And while cookies can be blocked or deleted, many websites rely on them to function, making it hard to escape this kind of tracking.

Even Incognito mode isn’t safe

Even if you’re using privacy-focused browsers or tools like Incognito mode, they don’t really guarantee privacy. A 2020 class-action lawsuit revealed that Google kept scraping searches by gathering data from users browsing in Incognito through ad tools used by websites, picking up “potentially embarrassing” searches from millions of people. Google then used that data to track web traffic and sell ads.

It’s not just Google. Your internet service provider, the websites you visit and even governments can monitor your browsing activity, even in Incognito mode. All it does is hide your activity from your local browser history.

How to protect your privacy 

As you all know, web browsers are essential tools for accessing the internet, but many popular options compromise your privacy by collecting extensive data. While Google Chrome is widely used, it tracks significant amounts of user information to power targeted advertising. However, there are several privacy-focused browser alternatives that prioritize user data protection. Also, to enhance your online security and protect your personal information, consider implementing these essential cybersecurity practices.

Keep software updated: Regularly update your operating system, browsers and other software to patch security vulnerabilities. Enable automatic updates whenever possible to ensure you’re always protected against the latest threats.

Use strong, unique passwords: Create complex passwords for each of your accounts and avoid reusing them. Consider using a password manager to generate and securely store strong passwords.

Enable two-factor authentication (2FA): Activate 2FA on all accounts that offer it. This adds an extra layer of security by requiring a second form of verification beyond your password.

Be cautious with emails and links: Avoid opening suspicious emails or clicking on unknown links. These could be phishing attempts designed to steal your information or infect your device with malware. The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.

Use secure networks: When using public Wi-Fi, connect through a VPN to encrypt your internet traffic. For sensitive transactions, stick to secure, private networks.

Be mindful of social media sharing: Limit the personal information you share on social media platforms and adjust your privacy settings to control who can view your posts.

VPN: Your first line of defense against browser spying: A VPN (virtual private network) encrypts your internet connection, making it difficult for anyone, including your browser, to track your online activities. By masking your IP address and routing your traffic through secure servers, a VPN not only protects your personal data from prying eyes but also helps you avoid targeted advertising and potential data breaches.

Regardless of whether you are new to VPNs or not, you’ll want to choose trusted VPN providers known for robust encryption and no-log policies to ensure your privacy. Whether for sensitive tasks or everyday use, reputable VPN services will boost both your security and speed. For the best VPN software, see my expert review of the best VPNs for browsing the web privately on your Windows, Mac, Android and iOS devices.

By implementing these security practices and using privacy-focused browsers, you can significantly enhance your online safety and protect your personal data while browsing the web. Remember, cybersecurity is an ongoing process that requires vigilance and regular updates to your practices.

WHY YOU SHOULD BE USING A VPN TO SAFEGUARD YOUR STOCK TRADING ACTIVITIES

Kurt’s key takeaway

The web browser is an essential tool for accessing the internet, but it also opens the door to a host of privacy and security risks. Whether it’s being tracked for ads, snooped on by your ISP or accidentally stumbling onto a malware-filled site, the risks are everywhere. Tools like Incognito mode or cookie-blocking can help a bit, but they’re not enough to truly protect you. If you’re serious about staying private and secure, you need to up your game. Use a VPN, be cautious about what you click on and stay informed about the ways your browser might be working against you.
