Internet browsers can potentially put your privacy and sensitive information at risk as they often collect data about your online activities. This includes websites you visited, search queries, and location information. 

This data can be used by advertising companies, third-party trackers, or even malicious actors to build profiles about your interests, behaviour, and preferences.

Browsers also store small files called cookies on your device, which can contain information like login credentials, browsing history, or user preferences.

While cookies can enhance user experience, they can also be exploited by attackers if they gain access to your device.

Browsers are usually vulnerable to phishing attacks, where malicious actors try to trick you into revealing sensitive information such as usernames, passwords, or credit card details.

Phishing attacks often involve fake websites or deceptive emails that mimic legitimate sources to deceive users.

While Browser Extensions and add-ons can enhance browser functionality, they can also introduce security risks. 

Malicious or poorly designed extensions may access your browsing history, inject unwanted advertisements, or even steal your data. It’s important to be cautious and only install trusted extensions from reputable sources.

Browsers also transmit data between your device and websites through network connections. If you connect to insecure or unencrypted networks, such as public Wi-Fi hotspots, hackers can intercept and potentially access your private information, such as passwords or credit card details.

Browsers, like any software, can have vulnerabilities that hackers may exploit.

Exploits can allow attackers to gain unauthorized access to your device, install malware, or steal sensitive data. Keeping your browser and operating system up to date with security patches helps mitigate these risks.
