How Hackers Hijack Your Browser
Hackers can take control of your browser through a method known as browser hijacking. By exploiting vulnerabilities, malicious software can manipulate your browsing experience, often without you realizing it. Here's how it works and what you can do to stay safe.
What is Browser Hijacking?
Browser hijacking occurs when malware or unwanted programs alter your browser settings. Common signs include:
- Unexpected homepage changes.
- Pop-ups or ads appearing frequently.
- Redirects to unfamiliar websites.
- New toolbars or extensions you didn’t install.
How Hackers Hijack Your Browser
- Malicious Extensions:
- Hackers create extensions that appear useful but include hidden malware.
- Once installed, these can monitor your activity or redirect you to phishing sites.
- Drive-by Downloads:
- Visiting a compromised website can trigger a download of malware without your consent.
- This malware may modify your browser’s settings.
- Phishing Links: Clicking on links in fraudulent emails or ads can install hijacking software.

- DNS Hijacking: Attackers manipulate your device’s DNS settings, redirecting you to malicious sites even if you type in legitimate URLs.
What Hackers Gain from Hijacking
