A third-party cookie is an HTTP cookie configured by a domain other than the one the user is currently visiting. These cookies allow third parties to monitor and collect data about users’ behavior across multiple websites to deliver targeted advertisements, analyze browsing patterns, and enhance user experiences.
However, third-party cookies are more dangerous than first-party cookies because they share data with third-party websites, increasing the risks of hacker attacks.
Malicious actors can use third-party cookies to discreetly monitor and steal users’ data, like passwords, usernames, and credit card details. Additionally, cybercriminals can inject malware into websites and access users’ devices.
How to Prevent Third-party Cookies
- Disable third-party cookies: Open your browser settings and deactivate third-party cookies to prevent them from accessing and tracking your online activity.
- Install anti-malware software: An anti-malware software will protect your device from harmful third-party cookies.
- Clear your cookies and browsing history: Deleting any data that third-party cookies store will make it difficult for hackers to access and benefit from your browsing behavior.
- Avoid clicking on suspicious links: Don’t click on links from unauthorized sources, as they might contain third-party malware cookies.
- Use ad blockers: This will significantly reduce the risk of malicious third-party cookies.
