Cross Site Tracking

How to Turn off Cross Site Tracking

Cross site tracking refers to the method through which websites and third-party entities gather information about your online activities across different sites. This is often done using technologies like cookies to track your browsing habits, preferences, and interactions. The information collected can be used for targeted advertising, personalized content delivery, or even sold to other companies without your consent. 

Protecting privacy online is crucial because it helps safeguard your personal information from being exploited or misused. By limiting cross-site tracking, you maintain greater control over your digital footprint, reducing the chances of invasive ads, data breaches, and potential identity theft. It’s about ensuring that your online activities remain private and secure, allowing you to browse the web with confidence and peace of mind.

How Cross Site Tracking Works

Cross-site tracking operates by employing various techniques to monitor and record your online behavior as you navigate through different websites.

  1. Cookies: Websites often place small text files called cookies on your browser when you visit them. These cookies contain unique identifiers that allow sites to recognize you when you revisit them or move to other sites within their network.
  2. Tracking Pixels: These are tiny, invisible images embedded in web pages or emails. When your browser loads a page containing a tracking pixel, it sends a request to the server hosting the pixel, which can then track your activity, such as whether you opened an email or visited a specific webpage.
  3. Device Fingerprinting: This method involves collecting information about your device, such as its operating system, browser version, screen resolution, and installed plugins. By analyzing this data, trackers can create a unique fingerprint for your device, enabling them to identify you across different websites.
  4. Cross-site Scripting (XSS): Malicious actors can inject scripts into legitimate websites, which then execute in your browser when you visit those sites. These scripts can perform various actions, including tracking your activity and sending the data to remote servers.
  5. Browser Fingerprinting: Similar to device fingerprinting, browser fingerprinting collects information about your browser configuration and settings, such as installed fonts, timezone, and browser extensions. This information can be used to create a unique identifier for your browser, allowing trackers to recognize you across different websites.

Types of Cross Site Tracking Technologies

Cross-site tracking utilizes various technologies to monitor and record user activities across different websites.

Tracking Pixels

Tracking pixels, also called web beacons, are tiny, transparent images hidden within web pages or emails. When you open a webpage or an email containing a tracking pixel, it quietly sends a request to the server hosting the pixel. This action lets the server know that you’ve interacted with the content, allowing it to track your visit and gather information about your online activity.

These pixels are so small that they’re usually invisible to the naked eye, making them an effective tool for covert tracking. They’re commonly used by advertisers and marketers to monitor user engagement with online content and to gather data for targeted advertising campaigns.

Local Storage

Local storage is another method used by websites to store data in your web browser. Unlike cookies, which are sent to the server with every request, local storage data stays on your browser and isn’t automatically transmitted. This makes it useful for storing information that needs to persist across different sessions, such as user preferences or login credentials.

However, local storage can also be used for tracking purposes. Websites can store unique identifiers or other tracking data in your browser’s local storage, allowing them to recognize you when you revisit the site. While local storage offers some benefits for user experience, its potential for tracking raises privacy concerns.

Device Fingerprinting

Device fingerprinting is a method used to gather information about your device, such as its operating system, browser version, screen resolution, and installed plugins. This information is then used to create a unique fingerprint for your device, allowing trackers to identify and track you across different websites.

Unlike cookies or tracking pixels, device fingerprinting doesn’t rely on storing data in your browser. Instead, it gathers information about your device’s characteristics, which can be used to distinguish it from other devices. While individual data points collected through device fingerprinting might seem innocuous, when combined, they can create a highly accurate and persistent identifier for your device.

Browser Fingerprinting

Browser fingerprinting is a technique used to collect information about your browser configuration and settings. This includes details such as installed fonts, timezone, browser extensions, and more. By analyzing this data, trackers can create a unique fingerprint for your browser, allowing them to recognize and track you across different websites.

Unlike device fingerprinting, which focuses on gathering information about your device, browser fingerprinting specifically targets the characteristics of your browser. This makes it possible to track users even if they switch devices or use different browsers on the same device.

Cross-Site Scripting

Cross-Site Scripting (XSS) is a security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. These scripts can then execute in the browsers of unsuspecting visitors, enabling the attacker to steal sensitive information, manipulate the appearance of the page, or perform other malicious actions.

There are two main types of XSS attacks: persistent (or stored) XSS and non-persistent (or reflected) XSS. In a persistent XSS attack, the malicious script is permanently stored on the web server, affecting all users who visit the compromised page. In a non-persistent XSS attack, the script is temporarily injected into a URL or form input and is only executed when a specific user interacts with the manipulated page.

XSS attacks can have serious consequences, including the theft of login credentials, session hijacking, and the spread of malware. To mitigate the risk of XSS attacks, web developers should implement proper input validation and output encoding techniques, while users should be cautious when clicking on links or entering sensitive information on websites.

Risks Associated with Cross Site Tracking

Cross-site tracking poses various risks to users’ privacy and security.

  • Cross-site tracking allows companies to build detailed profiles of users’ browsing habits, interests, and preferences. This extensive tracking infringes on users’ privacy by enabling advertisers and data brokers to collect vast amounts of personal information without their explicit consent.
  • One of the primary purposes of cross-site tracking is to deliver targeted advertisements based on users’ online behavior. While some users may find personalized ads useful, others may feel uncomfortable with the level of surveillance involved in tracking their every move online.
  • Storing large quantities of personal data collected through cross-site tracking increases the risk of data breaches. If this data falls into the wrong hands, it can be exploited for identity theft, fraud, or other malicious purposes, posing a significant threat to users’ financial and personal security.
  • By aggregating data collected from multiple websites, trackers can create detailed profiles of individual users. These profiles may contain sensitive information about users’ interests, political views, health conditions, and more, which could be used for discriminatory purposes or to manipulate users’ behavior.
  • Cross-device tracking extends the reach of cross-site tracking by linking users’ activities across multiple devices, such as smartphones, tablets, and computers. This seamless tracking across devices further erodes users’ privacy and makes it challenging to escape from persistent surveillance.
